91/**
92 * struct mtk_mmsys_driver_data - Settings of the mmsys
93 * @clk_driver: Clock driver name that the mmsys is using
94 *              (defined in drivers/clk/mediatek/clk-*.c).
95 * @routes: Routing table of the mmsys.
96 *          It provides mux settings from one module to another.
97 * @num_routes: Array size of the routes.
98 * @sw0_rst_offset: Register offset for the reset control.
99 * @num_resets: Number of reset bits that are defined
100 * @is_vppsys: Whether the mmsys is VPPSYS (Video Processing Pipe)
101 *             or VDOSYS (Video). Only VDOSYS needs to be added to drm driver.
102 * @vsync_len: VSYNC length of the MIXER.
103 *             VSYNC is usually triggered by the connector, so its length is a
104 *             fixed value when the frame rate is decided, but ETHDR and
105 *             MIXER generate their own VSYNC due to hardware design, therefore
106 *             MIXER has to sync with ETHDR by adjusting VSYNC length.
107 *             On MT8195, there is no such setting so we use the gap between
108 *             falling edge and rising edge of SOF (Start of Frame) signal to
109 *             do the job, but since MT8188, VSYNC_LEN setting is introduced to
110 *             solve the problem and is given 0x40 (ticks) as the default value.
111 *             Please notice that this value has to be set to 1 (minimum) if
112 *             ETHDR is bypassed, otherwise MIXER could wait too long and causing
113 *             underflow.
114 *
115 * Each MMSYS (multi-media system) may have different settings, they may use
116 * different clock sources, mux settings, reset control ...etc., and these
117 * differences are all stored here.
