2024-04-29mcb: lpc: Convert to platform remove callback returning voidUwe Kleine-König1-4/+2
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new(), which already returns void. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

https://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into char-misc-next Jonathan writes: IIO: 1st set of new device support, features and cleanup for 6.10 The Analog Device team (Paul Cercueil and Nuno Sa) have been working on improving high speed device handling. They have had some support in their own tree for many years, so it is great to see them bring it to upstream. Some of that is seen here, with the first output device using the IIO dmaengine infrastructure and a new DAC backend FPGA IP driver. This makes use of a new set of interfaces to allow backend and front end driver communication in a fashion that in theory at least allows for a single driver for a given ADC / DAC independent of the IP to which is being used to deal with the data bus and DMA aspects of working with these devices. It is early days for this new generic way of handling split devices, but as it's kernel internals only we can merrily change anything about it as a wider diversity of devices show up and we get a better feel for what works. Alongside the usual set of new drivers and features we have the automatic cleanup of fwnode_handle_put() which didn't quite make it in last cycle. The equivalent DT version was merged by Rob Herring via the DT binding tree and one patch using that in IIO can also be found in this pull request. Rob has been making extensive use of that infrastructure in the DT core which is good to see and provides more evidence this basic approach is useful. In some cases, the IIO driver was converted over from DT only to using the generic firmware description handling of property.h including using the new macros. The general preference for IIO is to use this more generic handling where possible - a bunch of other drivers have been converted this cycle as well. New device support ================== adi,ad7173 - New driver supporting AD7172-2, AD7172-4 AD7173-9, AD7175-2, AD7175-8, AD7176-2 and AD7177-2 ADCs. - Follow up fix for an accidental use of logic not instead of bitwise. adi,ad7944 - New driver supporting AD7944, AD7985 and AD7986 pin compatible ADCs. - Later patch added use of new spi_optimize_message() to reduce overheads of setting up a reused message. - Additional changes later in series reduced code duplication. adi,ad9739a RF DAC - New driver for this 14-bit 2.5 GSPS DAC via an LVDS interface. adi,axi-dac - Support for this FPGA IP used to send data to high performance DACs over an interface such as JESD204B/C or parallel interfaces. Used in conjunction with a DAC driver. The initial user is the ad9739a. The dmaengine-buffer needed various changes to make it bidirectional. avago,apds9306 - New driver for this ambient light sensor. - Fix much later in this pull for an off by 1 error. New device IDs ============== For these at most an ID and a instance of chip specific data was needed. Always nice to see manufacturers sticking to an existing software interface for new parts. allwinner,sun20i - Add support for h616. invensense,mpu6050 - Add support for ICM42688 maxim,max30102 - Add compatible for MAX30101 ti,dac5571 - Add compatible for DAC081C081 General ======= fwnode_handle - Support for cleanup.h based __free(fwnode_handle) - Loop macro using this for looping over child nodes without needing to call fwnode_handle_put() in ever early exit from the loop. - Used in: * adi,ad3552r * adi,ad4130 * adi,ad5770r * adi,ad74413r * adi,ad7173 * adi,adfm2000 * linear,ltc2688 * linear,ltc2983 * maxim,max11410 * microchip,pac1934 * qcom,spmi-adc * renesas,rz2gl * st,ab8500 * st,stm32 (Fix for failure to set return value precedes this patch, providing an example of why enabling direct returns makes bugs less likely) - Conversions to fwnode also using the cleanup logic * adi,ad7124 * adi,ad7292 * freescale,fsl-imx25-gcq - Other conversions to fwnode where the new cleanup handling isn't useful * adi,ad7192 * avia,hx711 * freescale,mma8452 * nxp,fxls8962af * st,spear * ti,twl4030 Features ======== adi,adxl345 - Support SPI_3WIRE mode. adi,ad9944 - Support 3-wire mode, note this isn't normal 3-wire SPI (unlike the adxl345 change above), but rather a wiring scheme where the SPI chip select is used to trigger conversions rather than using a separate pin. - Add some device specific documentation, mostly around the various wiring schemes. invensense,mpu6050 - Add Wake on Motion support as an IIO event and as a wake-up source. linear,ltc2983 - Add vdd-supply. ti,hdc3020 - Add power management using trigger on demand mode and adding suspend and resume handling. - Use reset GPIO if available. Cleanup and fixes ================ iio core - Use the various autocleanup and lock guards from cleanup.h to simplify the IIO core. - Don't set the pointer used for iio_priv() if it is zero sized as that points beyond the end of the allocation. No driver actually uses it in that case but good to clean this up. various drivers - Drop unnecessary casts of other pointer types to void * docs - Add missing ABI entry for in_temp_input. adi,adx345 - General cleanup prior to adding spi-3wire mode. adi,axi-adc - Be more flexible and allow minor version changes as these are expected to be backwards compatible. avago,apds9300/9600 - Merge near identical bindings. The drivers are quite different, but the bindings can be shared. The apds9306 binding introduced in this series uses this shared binding doc as well. - Add missing vdd-supply - Update binding to use IRQ_TYPE_LEVEL_LOW instead of 8. bosch,bmp280 - Organize headers freescale,fxl-imx25-gcq - Use devm_ for remaining probe() time setup allowing dropping of specific error handling and remove() functions. infineon,dps310 - Fix handling of negative temperatures - Bring style of other similar calls inline with the form needed for temperatures - Ensure error handling of regmap calls is consistent within the driver. - Simplify scale reading logic. invensense,mpu6050 - Flip logic in binding to exclude devices without i2c-gate instead of opting in. The list is expected to be much shorter as all recent devices support this feature. honeywell,hsc030pa - Use spi_read() instead of opening coding. renesas,rcar - Use device_for_each_child_of_node_scoped() to remove need to manually release. Left over from series the rest of which went in during 6.9. st,ab8500 - Fix naming of function parameters in kernel-doc * tag 'iio-for-6.10a' of https://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio: (108 commits) iio: adc: ti-ads131e08: Use device_for_each_child_node_scoped() to simplify error paths. iio: adc: adi-axi-adc: only error out in major version mismatch iio: dac: support the ad9739a RF DAC iio: dac: add support for AXI DAC IP core iio: backend: add new functionality dt-bindings: iio: dac: add docs for AD9739A dt-bindings: iio: dac: add docs for AXI DAC IP iio: buffer-dmaengine: Enable write support iio: buffer-dmaengine: Support specifying buffer direction iio: buffer-dma: Enable buffer write support iio: buffer-dma: Rename iio_dma_buffer_data_available() iio: buffer-dma: add iio_dmaengine_buffer_setup() iio: pressure: dps310: simplify scale factor reading iio: pressure: dps310: consistently check return value of `regmap_read` iio: pressure: dps310: introduce consistent error handling iio: pressure: dps310: support negative temperature values dt-bindings: iio: adc: Add GPADC for Allwinner H616 iio: dac: ad5755: make use of of_device_id table iio: imu: inv_icm42600: add support of ICM-42688-P dt-bindings: iio: imu: add icm42688 inside inv_icm42600 ...

Pull kvm fixes from Paolo Bonzini: "This is a bit on the large side, mostly due to two changes: - Changes to disable some broken PMU virtualization (see below for details under "x86 PMU") - Clean up SVM's enter/exit assembly code so that it can be compiled without OBJECT_FILES_NON_STANDARD. This fixes a warning "Unpatched return thunk in use. This should not happen!" when running KVM selftests. Everything else is small bugfixes and selftest changes: - Fix a mostly benign bug in the gfn_to_pfn_cache infrastructure where KVM would allow userspace to refresh the cache with a bogus GPA. The bug has existed for quite some time, but was exposed by a new sanity check added in 6.9 (to ensure a cache is either GPA-based or HVA-based). - Drop an unused param from gfn_to_pfn_cache_invalidate_start() that got left behind during a 6.9 cleanup. - Fix a math goof in x86's hugepage logic for KVM_SET_MEMORY_ATTRIBUTES that results in an array overflow (detected by KASAN). - Fix a bug where KVM incorrectly clears root_role.direct when userspace sets guest CPUID. - Fix a dirty logging bug in the where KVM fails to write-protect SPTEs used by a nested guest, if KVM is using Page-Modification Logging and the nested hypervisor is NOT using EPT. x86 PMU: - Drop support for virtualizing adaptive PEBS, as KVM's implementation is architecturally broken without an obvious/easy path forward, and because exposing adaptive PEBS can leak host LBRs to the guest, i.e. can leak host kernel addresses to the guest. - Set the enable bits for general purpose counters in PERF_GLOBAL_CTRL at RESET time, as done by both Intel and AMD processors. - Disable LBR virtualization on CPUs that don't support LBR callstacks, as KVM unconditionally uses PERF_SAMPLE_BRANCH_CALL_STACK when creating the perf event, and would fail on such CPUs. Tests: - Fix a flaw in the max_guest_memory selftest that results in it exhausting the supply of ucall structures when run with more than 256 vCPUs. - Mark KVM_MEM_READONLY as supported for RISC-V in set_memory_region_test" * tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm: (30 commits) KVM: Drop unused @may_block param from gfn_to_pfn_cache_invalidate_start() KVM: selftests: Add coverage of EPT-disabled to vmx_dirty_log_test KVM: x86/mmu: Fix and clarify comments about clearing D-bit vs. write-protecting KVM: x86/mmu: Remove function comments above clear_dirty_{gfn_range,pt_masked}() KVM: x86/mmu: Write-protect L2 SPTEs in TDP MMU when clearing dirty status KVM: x86/mmu: Precisely invalidate MMU root_role during CPUID update KVM: VMX: Disable LBR virtualization if the CPU doesn't support LBR callstacks perf/x86/intel: Expose existence of callback support to KVM KVM: VMX: Snapshot LBR capabilities during module initialization KVM: x86/pmu: Do not mask LVTPC when handling a PMI on AMD platforms KVM: x86: Snapshot if a vCPU's vendor model is AMD vs. Intel compatible KVM: x86: Stop compiling vmenter.S with OBJECT_FILES_NON_STANDARD KVM: SVM: Create a stack frame in __svm_sev_es_vcpu_run() KVM: SVM: Save/restore args across SEV-ES VMRUN via host save area KVM: SVM: Save/restore non-volatile GPRs in SEV-ES VMRUN via host save area KVM: SVM: Clobber RAX instead of RBX when discarding spec_ctrl_intercepted KVM: SVM: Drop 32-bit "support" from __svm_sev_es_vcpu_run() KVM: SVM: Wrap __svm_sev_es_vcpu_run() with #ifdef CONFIG_KVM_AMD_SEV KVM: SVM: Create a stack frame in __svm_vcpu_run() for unwinding KVM: SVM: Remove a useless zeroing of allocated memory ...

The fix is to keep the device runtime resumed while registering clks. - Another runtime PM related deadlock, this time with disabling unused clks during late init. We get an ABBA deadlock where a device is runtime PM resuming (or suspending) while the disabling of unused clks is happening in parallel. That runtime PM action calls into the clk framework and tries to grab the clk prepare_lock while the disabling of unused clks holds the prepare_lock and is waiting for that runtime PM action to complete. The fix is to runtime resume all the clk provider devices before grabbing the clk prepare_lock during disable unused. - A build fix to provide an empty devm_clk_rate_exclusive_get() function when CONFIG_COMMON_CLK=n" * tag 'clk-fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: clk: mediatek: mt7988-infracfg: fix clocks for 2nd PCIe port clk: mediatek: Do a runtime PM get on controllers during probe clk: Get runtime PM before walking tree for clk_summary clk: Get runtime PM before walking tree during disable_unused clk: Initialize struct clk_core kref earlier clk: Don't hold prepare_lock when calling kref_put() clk: Remove prepare_lock hold assertion in __clk_release() clk: Provide !COMMON_CLK dummy for devm_clk_rate_exclusive_get()
2024-04-20iio: adc: adi-axi-adc: only error out in major version mismatchNuno Sa1-2/+2
The IP core only has breaking changes when there major version changes. Hence, only match the major number. This is also in line with the other core ADI has upstream. The current check for erroring out 'expected_version > current_version"' is then wrong as we could just increase the core major with breaking changes and that would go unnoticed.

The AD9739A is a 14-bit, 2.5 GSPS high performance RF DACs that are capable of synthesizing wideband signals from DC up to 3 GHz. A dual-port, source synchronous, LVDS interface simplifies the digital interface with existing FGPA/ASIC technology. On-chip controllers are used to manage external and internal clock domain variations over temperature to ensure reliable data transfer from the host to the DAC core.

2024-04-20iio: dac: add support for AXI DAC IP coreNuno Sa4-0/+658
Support the Analog Devices Generic AXI DAC IP core. The IP core is used for interfacing with digital-to-analog (DAC) converters that require either a high-speed serial interface (JESD204B/C) or a source synchronous parallel interface (LVDS/CMOS). Typically (for such devices) SPI will be used for configuration only, while this IP core handles the streaming of data into memory via DMA.

2024-04-20iio: buffer-dma: Enable buffer write supportPaul Cercueil2-16/+75
Adding write support to the buffer-dma code is easy - the write() function basically needs to do the exact same thing as the read() function: dequeue a block, read or write the data, enqueue the block when entirely processed. Therefore, the iio_buffer_dma_read() and the new iio_buffer_dma_write() now both call a function iio_buffer_dma_io(), which will perform this task. Note that we preemptively reset block->bytes_used to the buffer's size in iio_dma_buffer_request_update(), as in the future the iio_dma_buffer_enqueue() function won't reset it.

2024-04-20iio: buffer-dma: add iio_dmaengine_buffer_setup()Nuno Sa3-45/+24
This brings the DMA buffer API more in line with what we have in the triggered buffer. There's no need of having both devm_iio_dmaengine_buffer_setup() and devm_iio_dmaengine_buffer_alloc(). Hence we introduce the new iio_dmaengine_buffer_setup() that together with devm_iio_dmaengine_buffer_setup() should be all we need. Note that as part of this change iio_dmaengine_buffer_alloc() is again static and the axi-adc was updated accordingly.

2024-04-20iio: pressure: dps310: simplify scale factor readingThomas Haemmerle1-6/+6
Both functions `dps310_get_pres_precision` and `dps310_get_temp_precision` provide the oversampling rate by calling the `BIT()` macro. However, to look up the corresponding scale factor, we need the register value itself. Currently, this is achieved by undoing the calculation of the oversampling rate with `ilog2()`. Simplify the two functions for getting the scale factor and directly use the register content for the lookup.

The current implementation interprets negative values returned from `dps310_calculate_temp` as error codes. This has a side effect that when negative temperature values are calculated, they are interpreted as error. Fix this by using the return value only for error handling and passing a pointer for the value.
