* struct mtk_mmsys_driver_data - Settings of the mmsys
* @ clk_driver : Clock driver name that the mmsys is using
* ( defined in drivers / clk / mediatek / clk - * . c ) .
* @ routes : Routing table of the mmsys .
* It provides mux settings from one module to another .
* @ num_routes : Array size of the routes .
* @ sw0_rst_offset : Register offset for the reset control .
* @ num_resets : Number of reset bits that are defined
* @ is_vppsys : Whether the mmsys is VPPSYS ( Video Processing Pipe )
* or VDOSYS ( Video ) . 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 0 x40 ( 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 .
