The T820, G31 & G52 GPUs integrated by Amlogic in the respective GXM, G12A/SM1 & G12B SoCs needs a quirk in the PWR registers at the GPU reset time. This serie adds the necessary quirks for the Amlogic integrated GPUs only. Changes since v1 at [1]: - removed the BROKEN_SH quirk after [2] was sent by robin - rebased on top of [3] by steven and moved the vendor quirk in the proper quirk function - added PWR_KEY unlock definition, and cleaned definition [1] https://lkml.kernel.org/r/20200908151853.4837-1-narmstrong@xxxxxxxxxxxx [2] https://lkml.kernel.org/r/cover.1600213517.git.robin.murphy@xxxxxxx [3] https://lkml.kernel.org/r/20200909122957.51667-1-steven.price@xxxxxxx Neil Armstrong (3): drm/panfrost: add support for vendor quirk drm/panfrost: add amlogic reset quirk callback drm/panfrost: add Amlogic GPU integration quirks drivers/gpu/drm/panfrost/panfrost_device.h | 3 +++ drivers/gpu/drm/panfrost/panfrost_drv.c | 11 +++++++++++ drivers/gpu/drm/panfrost/panfrost_gpu.c | 15 +++++++++++++++ drivers/gpu/drm/panfrost/panfrost_gpu.h | 2 ++ drivers/gpu/drm/panfrost/panfrost_regs.h | 4 ++++ 5 files changed, 35 insertions(+) -- 2.22.0 _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
