2020-03-18drm: convert .debugfs_init() hook to return void.Wambui Karuga5-16/+8
As a result of commit 987d65d01356 (drm: debugfs: make drm_debugfs_create_files() never fail) and changes to various debugfs functions in drm/core and across various drivers, there is no need for the drm_driver.debugfs_init() hook to have a return value. Therefore, declare it as void. This also includes refactoring all users of the .debugfs_init() hook to return void across the subsystem. v2: include changes to the hook and drivers that use it in one patch to prevent driver breakage and enable individual successful compilation of this change.

2020-03-18drm/msm: remove checks for return value of drm_debugfs_create_files()Wambui Karuga3-29/+10
Since commit 987d65d01356 (drm: debugfs: make drm_debugfs_create_files() never fail), drm_debugfs_create_files never fails and only returns 0. Therefore, the unnecessary checks for its return value and error handling in various debugfs_init() functions in drm/msm and have the functions return 0 directly. v2: have debug functions return 0 instead of void to avoid build breakage and ensure standalone compilation.

2020-02-26drm/bridge: Extend bridge API to disable connector creationLaurent Pinchart5-6/+6
Most bridge drivers create a DRM connector to model the connector at the output of the bridge. This model is historical and has worked pretty well so far, but causes several issues: - It prevents supporting more complex display pipelines where DRM connector operations are split over multiple components. For instance a pipeline with a bridge connected to the DDC signals to read EDID data, and another one connected to the HPD signal to detect connection and disconnection, will not be possible to support through this model. - It requires every bridge driver to implement similar connector handling code, resulting in code duplication. - It assumes that a bridge will either be wired to a connector or to another bridge, but doesn't support bridges that can be used in both positions very well (although there is some ad-hoc support for this in the analogix_dp bridge driver). In order to solve these issues, ownership of the connector should be moved to the display controller driver (where it can be implemented using helpers provided by the core). Extend the bridge API to allow disabling connector creation in bridge drivers as a first step towards the new model. The new flags argument to the bridge .attach() operation allows instructing the bridge driver to skip creating a connector. Unconditionally set the new flags argument to 0 for now to keep the existing behaviour, and modify all existing bridge drivers to return an error when connector creation is not requested as they don't support this feature yet. The change is based on the following semantic patch, with manual review and edits. @ rule1 @ identifier funcs; identifier fn; @@ struct drm_bridge_funcs funcs = { ..., .attach = fn }; @ depends on rule1 @ identifier rule1.fn; identifier bridge; statement S, S1; @@ int fn( struct drm_bridge *bridge + , enum drm_bridge_attach_flags flags ) { ... when != S + if (flags & DRM_BRIDGE_ATTACH_NO_CONNECTOR) { + DRM_ERROR("Fix bridge driver to make connector optional!"); + return -EINVAL; + } + S1 ... } @ depends on rule1 @ identifier rule1.fn; identifier bridge, flags; expression E1, E2, E3; @@ int fn( struct drm_bridge *bridge, enum drm_bridge_attach_flags flags ) { <... drm_bridge_attach(E1, E2, E3 + , flags ) ...> } @@ expression E1, E2, E3; @@ drm_bridge_attach(E1, E2, E3 + , 0 ) Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Boris Brezillon <boris.brezillon@collabora.com> Acked-by: Sam Ravnborg <sam@ravnborg.org> Reviewed-by: Tomi Valkeinen <tomi.valkeinen@ti.com> Tested-by: Sebastian Reichel <sebastian.reichel@collabora.com> Reviewed-by: Sebastian Reichel <sebastian.reichel@collabora.com> Acked-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com> Link: https://patchwork.freedesktop.org/patch/msgid/20200226112514.12455-10-laurent.pinchart@ideasonboard.com

Commit e812744c5f95 ("drm: msm: a6xx: Add support for A618") added a universal GBIF un-halt into a6xx_start(). This can cause problems for a630 targets which do not use GBIF and might have access protection enabled on the region now occupied by the GBIF registers. But it turns out that we didn't need to unhalt the GBIF in this path since the stop function already takes care of that after executing a flush but before turning off the headswitch. We should be confident that the GBIF is open for business when we restart the hardware.

I was hitting kCFI crashes when building with clang, and after some digging finally narrowed it down to the dsi_mgr_connector_mode_valid() function being implemented as returning an int, instead of an enum drm_mode_status. This patch fixes it, and appeases the opaque word of the kCFI gods (seriously, clang inlining everything makes the kCFI backtraces only really rough estimates of where things went wrong).

git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux Pull clk updates from Stephen Boyd: "There are a few changes to the core framework this time around, in addition to the normal collection of driver updates to support new SoCs, fix incorrect data, and convert various drivers to clk_hw based APIs. In the core, we allow clk_ops::init() to return an error code now so that we can fail clk registration if the callback does something like fail to allocate memory. We also add a new "terminate" clk_op so that things done in clk_ops::init() can be undone, e.g. free memory. We also spit out a warning now when critical clks fail to enable and we support changing clk rates and enable/disable state through debugfs when developers compile the kernel themselves. On the driver front, we get support for what seems like a lot of Qualcomm and NXP SoCs given that those vendors dominate the diffstat. There are a couple new drivers for Xilinx and Amlogic SoCs too. The updates are all small things like fixing the way glitch free muxes switch parents, avoiding div-by-zero problems, or fixing data like parent names. See the updates section below for more details. Finally, the "basic" clk types have been converted to support specifying parents with clk_hw pointers. This work includes an overhaul of the fixed-rate clk type to be more modern by using clk_hw APIs.

git://git.kernel.org:/pub/scm/linux/kernel/git/arnd/playground Pull y2038 updates from Arnd Bergmann: "Core, driver and file system changes These are updates to device drivers and file systems that for some reason or another were not included in the kernel in the previous y2038 series. I've gone through all users of time_t again to make sure the kernel is in a long-term maintainable state, replacing all remaining references to time_t with safe alternatives. Some related parts of the series were picked up into the nfsd, xfs, alsa and v4l2 trees. A final set of patches in linux-mm removes the now unused time_t/timeval/timespec types and helper functions after all five branches are merged for linux-5.6, ensuring that no new users get merged. As a result, linux-5.6, or my backport of the patches to 5.4 [1], should be the first release that can serve as a base for a 32-bit system designed to run beyond year 2038, with a few remaining caveats: - All user space must be compiled with a 64-bit time_t, which will be supported in the coming musl-1.2 and glibc-2.32 releases, along with installed kernel headers from linux-5.6 or higher. - Applications that use the system call interfaces directly need to be ported to use the time64 syscalls added in linux-5.1 in place of the existing system calls. This impacts most users of futex() and seccomp() as well as programming languages that have their own runtime environment not based on libc. - Applications that use a private copy of kernel uapi header files or their contents may need to update to the linux-5.6 version, in particular for sound/asound.h, xfs/xfs_fs.h, linux/input.h, linux/elfcore.h, linux/sockios.h, linux/timex.h and linux/can/bcm.h. - A few remaining interfaces cannot be changed to pass a 64-bit time_t in a compatible way, so they must be configured to use CLOCK_MONOTONIC times or (with a y2106 problem) unsigned 32-bit timestamps. Most importantly this impacts all users of 'struct input_event'. - All y2038 problems that are present on 64-bit machines also apply to 32-bit machines. In particular this affects file systems with on-disk timestamps using signed 32-bit seconds: ext4 with ext3-style small inodes, ext2, xfs (to be fixed soon) and ufs" [1] https://git.kernel.org/pub/scm/linux/kernel/git/arnd/playground.git/log/?h=y2038-endgame * tag 'y2038-drivers-for-v5.6-signed' of git://git.kernel.org:/pub/scm/linux/kernel/git/arnd/playground: (21 commits) Revert "drm/etnaviv: reject timeouts with tv_nsec >= NSEC_PER_SEC" y2038: sh: remove timeval/timespec usage from headers y2038: sparc: remove use of struct timex y2038: rename itimerval to __kernel_old_itimerval y2038: remove obsolete jiffies conversion functions nfs: fscache: use timespec64 in inode auxdata nfs: fix timstamp debug prints nfs: use time64_t internally sunrpc: convert to time64_t for expiry drm/etnaviv: avoid deprecated timespec drm/etnaviv: reject timeouts with tv_nsec >= NSEC_PER_SEC drm/msm: avoid using 'timespec' hfs/hfsplus: use 64-bit inode timestamps hostfs: pass 64-bit timestamps to/from user space packet: clarify timestamp overflow tsacct: add 64-bit btime field acct: stop using get_seconds() um: ubd: use 64-bit time_t where possible xtensa: ISS: avoid struct timeval dlm: use SO_SNDTIMEO_NEW instead of SO_SNDTIMEO_OLD ...

As such, if you compare the 2, you would deduce that the sg segment will overflow the device's capacity. In reality, the hardware can accommodate the larger sg segments, it's just not initializing its max segment properly. This patch initializes the max segment size for the mdss device, which gets rid of that pesky warning.

2020-01-07clk: mux: Add support for specifying parents via DT/pointersStephen Boyd2-4/+4
After commit fc0c209c147f ("clk: Allow parents to be specified without string names") we can use DT or direct clk_hw pointers to specify parents. Create a generic function that shouldn't be used very often to encode the multitude of ways of registering a mux clk with different parent information. Then add a bunch of wrapper macros that only pass down what needs to be passed down to the generic function to support this with less arguments. Note: the msm drm driver passes an anonymous array through the macro which seems to confuse my compiler. Adding a parenthesis around the whole thing at the call site seems to fix it but it must be wrong. Maybe it's better to split this patch and pick out the array bits there?
