/**
 * 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 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.
