2020-03-04drm/v3d: Replace wait_for macros to remove use of msleepJames Hughes
The wait_for macro's for Broadcom V3D driver used msleep, which is inappropriate due to its inaccuracy at low values (minimum wait time is about 30ms on the Raspberry Pi). This sleep was triggering in v3d_clean_caches(), causing us to only be able to dispatch ~33 compute jobs per second. This patch replaces the macro with the one from the Intel i915 version which uses usleep_range to provide more accurate waits. v2: Split from the vc4 patch so that we can confidently apply to stable (by anholt) Signed-off-by: James Hughes <james.hughes@raspberrypi.com> Signed-off-by: Eric Anholt <eric@anholt.net> Link: https://patchwork.freedesktop.org/patch/msgid/20200217153145.13780-1-james.hughes@raspberrypi.com Link: https://github.com/raspberrypi/linux/issues/3460 Fixes: 57692c94dcbe ("drm/v3d: Introduce a new DRM driver for Broadcom V3D V3.x+")

2020-03-02video: Replace zero-length array with flexible-array memberGustavo A. R. Silva
The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] This issue was found with the help of Coccinelle.

2020-02-29drm/panel: simple: add panel-dpi supportSam Ravnborg
The panel-dpi compatible is a fallback that allows the DT to specify the timing. When matching panel-dpi expect the device tree to include the timing information for the display-panel. Background for this change: There are a lot of panels and new models hits the market very often. It is a lost cause trying to chase them all and users of new panels will often find them in situations that the panel they ues are not supported by the kernel. On top of this a lot of panels are customized based on customer specifications. Including the panel timing in the device tree allows for a simple way to describe the actual HW and use this description in a generic way in the kernel. This allows uses of proprietary panels, or panels which are not included in the kernel, to specify the timing in the device tree together with all the other HW descriptions. And thus, using the device tree it is then easy to add support for an otherwise unknown panel. The current support expect panels that do not require any delays for prepare/enable/disable/unprepare. Oleksandr Suvorov replied: I've just tested this patch on Apalis iMX6Q and Colibri iMX7D using panel settings from the following patch: https://lore.kernel.org/linux-arm-kernel/20200115123401.2264293-4-oleksandr.suvorov@toradex.com/ It works for me, thanks!

2020-02-28drm/tidss: dispc: Fix broken plane positioning codeJyri Sarha
The old implementation of placing planes on the CRTC while configuring the planes was naive and relied on the order in which the planes were configured, enabled, and disabled. The situation where a plane's zpos was changed on the fly was completely broken. The usual symptoms of this problem was scrambled display and a flood of sync lost errors, when a plane was active in two layers at the same time, or a missing plane, in case when a layer was accidentally disabled. The rewrite takes a more straight forward approach when HW is concerned. The plane positioning registers are in the CRTC (or actually OVR) register space and it is more natural to configure them in a one go when configuring the CRTC. To do this we need make sure we have all the planes on the updated CRTCs in the new atomic state. The untouched planes on CRTCs that need plane position update are added to the atomic state in tidss_atomic_check().
