[PATCH v4] drm/mediatek: Fix mtk_cec_mask()
by Miles Chen 14 Jan '22

14 Jan '22

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.
