- Add register definitions for MT8188
- Add VDOSYS1 routing table
- Update MUTEX definitions accordingly
- Set VSYNC length from 0x40 (default) to 1 since ETHDR is bypassed

+ * struct mtk_mmsys_driver_data - settings for 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.
