These drivers don't use the driver_data member of struct i2c_device_id, so don't explicitly initialize this member. This prepares putting driver_data in an anonymous union which requires either no initialization or named designators. But it's also a nice cleanup on its own. While add it, also remove commas after the sentinel entries.

Remove color_mgmt_changed check from vop2_crtc_atomic_try_set_gamma to allow gamma LUT rewrite during modeset when coming out of suspend. Add a check for color_mgmt_changed directly in vop2_crtc_atomic_flush. This patch fixes the patch adding gamma LUT support for vop2 [1].

2024-12-11drm/panthor: Fix the fast-reset logicBoris Brezillon
If we do a GPU soft-reset, that's no longer fast reset. This also means the slow reset fallback doesn't work because the MCU state is only reset after a GPU soft-reset. Let's move the retry logic to panthor_device_resume() to issue a soft-reset between the fast and slow attempts, and patch panthor_gpu_suspend() to only power-off the L2 when a fast reset is requested. v3: - No changes v2: - Add R-b Signed-off-by: Boris Brezillon <boris.brezillon@collabora.com> Reviewed-by: Steven Price <steven.price@arm.com> Link: https://patchwork.freedesktop.org/patch/msgid/20241211075419.2333731-6-boris.brezillon@collabora.com
2024-12-11drm/panthor: Be robust against resume failuresBoris Brezillon
When the runtime PM resume callback returns an error, it puts the device in a state where it can't be resumed anymore. Make sure we can recover from such transient failures by calling pm_runtime_set_suspended() explicitly after a pm_runtime_resume_and_get() failure. v3: - Add R-b/A-b v2: - Add a comment explaining potential races in panthor_device_resume_and_get() Signed-off-by: Boris Brezillon <boris.brezillon@collabora.com> Reviewed-by: Adrian Larumbe <adrian.larumbe@collabora.com> Acked-by: Steven Price <steven.price@arm.com> Link: https://patchwork.freedesktop.org/patch/msgid/20241211075419.2333731-5-boris.brezillon@collabora.com

devfreq_{resume,suspend}_device() don't bother undoing the suspend_count modifications if something fails, so either it assumes failures are harmless, or it's super fragile/buggy.

This adds the glue code for the MIPI DSI2 bridge on Rockchip SoCs and enables its use on the RK3588. Right now the DSI2 controller is always paired with a DC-phy based on a Samsung IP, so the interface values are set statically for now. This stays true for the upcoming RK3576 as well.
