drm/mediatek: Fix mtk_cec_mask()

2022-04-06T14:34:28+00:00

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: Add HDMI support

2016-06-16T14:30:38+00:00

This patch adds drivers for the HDMI bridge connected to the DPI0 display subsystem function block, for the HDMI DDC block, and for the HDMI PHY to support HDMI output. This includes an interface to the generic hdmi-codec driver to start or stop audio playback and to retrieve ELD (EDID like data) to limit the supported audio formats to the HDMI sink capabilities.
