- Reset ID must starts from 0 and be consecutive, but the reset bits in our hardware design is not continuous, some bits are left unused, we need a map to solve the problem - Use old style 1-to-1 mapping if .rst_tb is not defined Reviewed-by: AngeloGioacchino Del Regno <angelogioacchino.delregno@collabora.com> Signed-off-by: Hsiao Chien Sung <shawn.sung@mediatek.com> Signed-off-by: AngeloGioacchino Del Regno <angelogioacchino.delregno@collabora.com>

* 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.
