drm/mediatek: dsi: Move mtk_dsi_stop() call back to mtk_dsi_poweroff()

2022-09-21T23:31:43Z

As the comment right before the mtk_dsi_stop() call advises, mtk_dsi_stop() should only be called after mtk_drm_crtc_atomic_disable(). That's because that function calls drm_crtc_wait_one_vblank(), which requires the vblank irq to be enabled. Previously mtk_dsi_stop(), being in mtk_dsi_poweroff() and guarded by a refcount, would only be called at the end of mtk_drm_crtc_atomic_disable(), through the call to mtk_crtc_ddp_hw_fini(). Commit cde7e2e35c28 ("drm/mediatek: Separate poweron/poweroff from enable/disable and define new funcs") moved the mtk_dsi_stop() call to mtk_output_dsi_disable(), causing it to be called before mtk_drm_crtc_atomic_disable(), and consequently generating vblank timeout warnings during suspend. Move the mtk_dsi_stop() call back to mtk_dsi_poweroff() so that we have a working vblank irq during mtk_drm_crtc_atomic_disable() and stop getting vblank timeout warnings.

drm/mediatek: dsi: Add atomic {destroy,duplicate}_state, reset callbacks

2022-08-25T14:54:05Z

Add callbacks for atomic_destroy_state, atomic_duplicate_state and atomic_reset to restore functionality of the DSI driver: this solves vblank timeouts when another bridge is present in the chain.

drm/mediatek: dpi: Add dp_intf support

2022-07-06T14:51:44Z

Dpintf is the displayport interface hardware unit. This unit is similar to dpi and can reuse most of the code. This patch adds support for mt8195-dpintf to this dpi driver. Main differences are: - 4 pixels for one iteration for dp_intf while dpi is 1 pixel for one iteration. - Input of dp_intf is two pixels per iteration. - Some register contents differ slightly between the two components.

drm/mediatek: dpi: Add pixels_per_iter config support

2022-07-06T14:32:07Z

The quantity of output for one iteration could be different for dpi and dp_intf. For dp_intf, it's 4 pixels for one iteration it's 1 pixel for one iteration for dpi. Therefore, we add a new config "pixels_per_iter" to control quantity of transferred pixels per iteration.

drm/mediatek: dpi: Add YUV422 output support

2022-07-06T14:22:10Z

Dp_intf supports YUV422 as output format. In MT8195 Chrome project, YUV422 output format is used for 4K resolution. To support this, it is also needed to support color format transfer. Color format transfer is a new feature for both dpi and dpintf of MT8195. The input format could be RGB888 and output format for dp_intf should be YUV422. Therefore, we add a mtk_dpi_matrix_sel() helper to update the DPI_MATRIX_SET register depending on the color format.

drm: Remove linux/media-bus-format.h from drm_crtc.h

drm_crtc.h has no need for linux/media-bus-format.h, so don't include it. Avoids useless rebuilds of the entire universe when touching linux/media-bus-format.h. Quite a few placs do currently depend on linux/media-bus-format.h without actually including it directly.
