drm/mediatek: dpi: Use mt8183 output formats for mt8192

2022-06-09T08:30:00+00:00

[ Upstream commit 7112e0b0a58be8575547eba6596c42710922674f ] The configuration for mt8192 was incorrectly using the output formats from mt8173. Since the output formats for mt8192 are instead the same ones as for mt8183, which require two bus samples per pixel, the pixelclock and DDR edge setting were misconfigured. This made external displays unable to show the image. Fix the issue by correcting the output format for mt8192 to be the same as for mt8183, fixing the usage of external displays for mt8192.

drm/mediatek: Fix mtk_cec_mask()

2022-06-09T08:29:56+00:00

[ Upstream commit 2c5d69b0a141e1e98febe3111e6f4fd8420493a5 ] In current implementation, mtk_cec_mask() writes val into target register and ignores the mask. After talking to our hdmi experts, mtk_cec_mask() should read a register, clean only mask bits, and update (val | mask) bits to the register.

drm/mediatek: Fix DPI component detection for MT8192

2022-06-09T08:29:56+00:00

[ Upstream commit cfab37ff31afcd0f99f3cccbff1f8ffa11e44c00 ] When support for MT8192 was added, the DPI device was not added to the list of components to look for. This causes the secondary display pipeline to not be able to fully bind, and the DRM driver subsequently defers probing. Add the DPI device compatible to list of DPI components to fix this.

drm/mediatek: Add vblank register/unregister callback functions

2022-06-09T08:29:56+00:00

[ Upstream commit b74d921b900b6ce38c6247c0a1c86be9f3746493 ] We encountered a kernel panic issue that callback data will be NULL when it's using in ovl irq handler. There is a timing issue between mtk_disp_ovl_irq_handler() and mtk_ovl_disable_vblank(). To resolve this issue, we use the flow to register/unregister vblank cb: - Register callback function and callback data when crtc creates. - Unregister callback function and callback data when crtc destroies. With this solution, we can assure callback data will not be NULL when vblank is disable.
