git://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux into arm/drivers Qualcomm driver updates for v5.20 This introduces a new driver that requests interconnect bandwidth based on throughput measurements of the bwmon hardware blocks found associated with, among other things, the CPU subsystem on many Qualcomm platforms. It introduces support for the SCM wrapper driver to vote for interconnect bandwidth for operations that needs bandwidth to the crypto engine. This ensures both performance and guards against issues caused by lacking votes for this path. The socinfo driver gains knowledge about the SC7180P SoC. It contains a range of fixes for spelling mistakes, refcount leaks in various drivers and removes some redundant code from the apr remove path. The SCM DT bindings are updated to declare support for QCS404, SM6125 and SDX65. The command db driver has a strncpy() converted to strscpy_pad() and then back again with proper documentation to why this was the right API. * tag 'qcom-drivers-for-5.20' of git://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux: soc: qcom: icc-bwmon: Add bandwidth monitoring driver dt-bindings: interconnect: qcom,msm8998-cpu-bwmon: add BWMON device soc/qcom: Make QCOM_RPMPD select PM_GENERIC_DOMAINS/_OF soc: qcom: aoss: Fix refcount leak in qmp_cooling_devices_register soc: qcom: llcc: Fix syntax errors in comments soc: qcom: ocmem: Fix refcount leak in of_get_ocmem dt-bindings: soc: qcom,wcnss: remove unneeded ref for names firmware: qcom_scm: Add bw voting support to the SCM interface dt-bindings: firmware: qcom-scm: Add interconnects property soc: qcom: cmd-db: replace strscpy_pad() with strncpy() dt-bindings: firmware: scm: Add compatible for SDX65 dt-bindings: arm: qcom: switch maintainer to Bjorn soc: qcom: rpmhpd: fix typos in comment soc: qcom: correct kerneldoc soc: qcom: cmd-db: replace strncpy() with strscpy_pad() firmware: qcom_scm-legacy: correct kerneldoc dt-bindings: firmware: document Qualcomm QCS404 and SM6125 SCM soc: qcom: apr: Drop redundant check in .remove() firmware: qcom_scm: drop unexpected word "the" soc: qcom: socinfo: Add an ID for sc7180P Link: https://lore.kernel.org/r/20220712021830.1271398-1-bjorn.andersson@linaro.org Signed-off-by: Arnd Bergmann <arnd@arndb.de>

2022-07-07soc: mediatek: SVS: Use DEFINE_SIMPLE_DEV_PM_OPS for svs_pm_opsNathan Chancellor1-1/+1
When building this driver for an architecture that does not support CONFIG_PM_SLEEP, such as hexagon, the following warnings occur: drivers/soc/mediatek/mtk-svs.c:1481:12: error: unused function 'svs_suspend' [-Werror,-Wunused-function] static int svs_suspend(struct device *dev) ^ drivers/soc/mediatek/mtk-svs.c:1515:12: error: unused function 'svs_resume' [-Werror,-Wunused-function] static int svs_resume(struct device *dev) ^ 2 errors generated. This happens because SIMPLE_DEV_PM_OPS uses SET_SYSTEM_SLEEP_PM_OPS, which evaluates to nothing when CONFIG_PM_SLEEP is not set, leaving the functions unused in the eyes of the compiler. This problem was rectified in commit 1a3c7bb08826 ("PM: core: Add new *_PM_OPS macros, deprecate old ones") with new macros. Use DEFINE_SIMPLE_DEV_PM_OPS to fix the warning while not changing svs_pm_ops when CONFIG_PM_SLEEP is set.

MediaTek SoCs have multiple MFG power-domains, exclusively used for the GPU which, in turn, requires external power supplies: make sure to have the MTK_SCPD_DOMAIN_SUPPLY cap on the two topmost MFGs to allow voting for regulators on/off upon usage of these power domains. This also ensures that the SRAM is actually powered and that we're not relying on the bootloader leaving this supply on when performing the first (and latter) poweron sequence for these domains' sram.

2022-07-06soc: qcom: icc-bwmon: Add bandwidth monitoring driverKrzysztof Kozlowski3-0/+437
Bandwidth monitoring (BWMON) sits between various subsytems like CPU, GPU, Last Level caches and memory subsystem. The BWMON can be configured to monitor the data throuhput between memory and other subsytems. The throughput is measured within specified sampling window and is used to vote for corresponding interconnect bandwidth. Current implementation brings support for BWMON v4, used for example on SDM845 to measure bandwidth between CPU (gladiator_noc) and Last Level Cache (memnoc). Usage of this BWMON allows to remove fixed bandwidth votes from cpufreq (CPU nodes) thus achieve high memory throughput even with lower CPU frequencies. The driver was tested on SDM845.

This driver exists as a workaround for old devicetrees which are missing interconnects properties, so it is only useful for those specific platforms, which all happen to be ARM or ARM64.

2022-06-29firmware: xilinx: Add TF_A_PM_REGISTER_SGI SMC callTanmay Shah1-3/+2
SGI interrupt register and reset is performed by EEMI ioctl IOCTL_REGISTER_SGI. However, this is not correct use of EEMI call. SGI registration functionality does not qualify as energy management activity and so shouldn't be mapped to EEMI call. This new call will replace IOCTL_REGISTER_SGI and will be handled by TF-A specific handler in TF-A. To maintain backward compatibility for a while firmware driver will still use IOCTL_REGISTER_SGI as fallback strategy if new call fails or is not supported by TF-A. This new design also helps to make TF-A as pass through layer for EEMI calls. So we don't have to maintain PM_IOCTL as EEMI API ID in TF-A.

Commit ac0126a01735 ("soc: qcom: cmd-db: replace strncpy() with strscpy_pad()") breaks booting on my sc7280-herobrine-herobrine device. From printouts I see that at bootup the function is called with an id of "lnbclka2" which is 8 bytes big. Previously all 8 bytes of this string were copied to the destination. Now only 7 bytes will be copied since strscpy_pad() saves a byte for '\0' termination. We don't need the '\0' termination in the destination. Let's go back to strncpy(). According to the warning: If a caller is using non-NUL-terminated strings, strncpy() can still be used, but destinations should be marked with the __nonstring attribute to avoid future compiler warnings. ...so we'll do that. While we're at it, let's change the query array to use "sizeof(ent->id)" so it can't possibly go out of sync with our later copy.

2022-06-27soc: fsl: guts: add serial_number supportMichael Walle1-2/+46
Most layerscapes provide a security fuse processor where the vendor will store a unique id per part. Unfortunately, we cannot use the corresponding efuse driver because this driver needs to be ready early during the boot phase. To get the unique identifier, we just need to access two registers. Thus we just search the device tree for the corresponding device, map its memory to read the id and then unmap it again. Because it is likely that the offset within the fuses is dependent on the SoC, we need a per SoC data. Also, the compatible string is different among the SoCs. For now, this add support for the LS1028A SoC. Signed-off-by: Michael Walle <michael@walle.cc> Acked-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Shawn Guo <shawnguo@kernel.org>
