2023-10-11gpu: host1x: Syncpoint interrupt shardingMikko Perttunen
Support sharded syncpoint interrupts on Tegra234+. This feature allows specifying one of eight interrupt lines for each syncpoint to lower processing latency of syncpoint threshold interrupts.

2023-10-11gpu: host1x: Enable system suspend callbacksMikko Perttunen
With the previous CDMA stop fix, executing runtime PM ops around system suspend now makes channel submissions work after system suspend, so do that.

2023-10-11gpu: host1x: Stop CDMA before suspendingMikko Perttunen
Before going into suspend, wait all CDMA to go idle and stop it. This will ensure no channel is still active while we enter suspend, and ensures the driver doesn't think that CDMA is still active when coming back from suspend (as HW state has been reset).

2023-10-11drm/i915: enable W=1 warnings by defaultJani Nikula
We enable a bunch more compiler warnings than the kernel defaults. However, they've drifted to become a unique set of warnings, and have increasingly fallen behind from the W=1 set. Align with the W=1 warnings from scripts/Makefile.extrawarn for clarity, by copy-pasting them with s/KBUILD_CFLAGS/subdir-ccflags-y/ to make it easier to compare in the future. Some of the -Wextra warnings do need to be disabled, just like in Makefile.extrawarn, but take care to not disable them for W=2 or W=3 builds, depending on the warning. v2: Add back some -Wextra warning disables (Nathan) Cc: Arnd Bergmann <arnd@arndb.de> Cc: Nick Desaulniers <ndesaulniers@google.com> Cc: Nathan Chancellor <nathan@kernel.org> Cc: Masahiro Yamada <masahiroy@kernel.org> Reviewed-by: Nathan Chancellor <nathan@kernel.org> Reviewed-by: Masahiro Yamada <masahiroy@kernel.org> [Final s/KBUILD_CFLAGS/subdir-ccflags-y/ fix while applying] Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/69a812273091b6535ddc7f9346289d71bb30f43d.1697009258.git.jani.nikula@intel.com

2023-10-10drm/panel: boe-tv101wum-nl6: Completely pull GPW to VGL before TP termRuihai Zhou
The sta_himax83102 panel sometimes shows abnormally flickering horizontal lines. The front gate output will precharge the X point of the next pole circuit before TP(TouchPanel Enable) term starts, and wait until the end of the TP term to resume the CLK. For this reason, the X point must be maintained during the TP term. In abnormal case, we measured a slight leakage at point X. This because during the TP term, the GPW does not fully pull the VGL low, causing the TFT to not be closed tightly. To fix this, we completely pull GPW to VGL before entering the TP term. This will ensure that the TFT is closed tightly and prevent the abnormal display.

2023-10-10drm/i915: Fix VLV color state readoutVille Syrjälä
VLV was missed when the color.get_config() hook was added. Remedy that. Not really sure what the final plan here was since a bunch of color related readout was left in intel_display.c anyway, but that's for anothr day to figure out...

2023-10-09drm/amdgpu: fix SI failure due to doorbells allocationIcenowy Zheng
SI hardware does not have doorbells at all, however currently the code will try to do the allocation and thus fail, makes SI AMDGPU not usable.
