Hi,
this MT8173 DRM update addresses some issues, mostly reported by Tomasz Figa, Daniel Kurtz, and YT Shen. It also adds is PRIME support and two new patches to export drm_atomic_helper's wait_for_fences and use it in mtk_atomic_complete.
Changes since v6: - Improved binding documentation - Split disp_ovl driver from mtk_drm_crtc code - Added crtc and plane state atomic reset functions - Toned down debug messages - Improved error handling for hardware initialization - Get/put smi_larb in crtc_enable/disable - Added memory barrier before marking crtc state as ready - Changed crtc_disable to wait for vblank - Renamed component power_on/off to start/stop - Made component ops optional - Moved crtc creation from disp_ovl driver bind callback into mtk_drm_kms_init - Added support for DRIVER_PRIME feature - Moved DISP_OVL, DSI, DPI and component initialization into the respective drivers - Added DPI/DSI poweron/off refcounting and mtk_ddp_component start/stop callbacks to keep pixel clock enabled until crtc_disable, as suggested by CK - Removed mtk_hdmi_audio_data / mtk-hdmi-codec platform device creation for now, hdmi audio will be reworked.
The following patches are still needed to apply this on top of v4.4-rc1:
https://patchwork.kernel.org/patch/6825601/ ("arm64: dts: mt8173: add MT8173 display PWM driver support node"), https://patchwork.kernel.org/patch/7138531/ ("arm64: dts: mediatek: add xHCI & usb phy for mt8173"), https://patchwork.kernel.org/patch/6928651/ ("dts: mt8173: Add iommu/smi nodes for mt8173"), and
And to build:
https://patchwork.kernel.org/patch/6928621/ ("memory: mediatek: Add SMI driver"),
