Only VDOSYS needs to be added to drm driver. * @vsync_len: VSYNC length of the MIXER. * VSYNC is usually triggered by the connector, so its length is a * fixed value when the frame rate is decided, but ETHDR and * MIXER generate their own VSYNC due to hardware design, therefore * MIXER has to sync with ETHDR by adjusting VSYNC length. * On MT8195, there is no such setting so we use the gap between * falling edge and rising edge of SOF (Start of Frame) signal to * do the job, but since MT8188, VSYNC_LEN setting is introduced to * solve the problem and is given 0x40 (ticks) as the default value. * Please notice that this value has to be set to 1 (minimum) if * ETHDR is bypassed, otherwise MIXER could wait too long and causing * underflow. * * Each MMSYS (multi-media system) may have different settings, they may use * different clock sources, mux settings, reset control ...etc., and these * differences are all stored here.
