The Amlogic G12A/G12B/SM1 SoCs embeds a Synopsys DW-MIPI-DSI transceiver (ver 1.21a), with a custom glue managing the IP resets, clock and data inputs similar to the DW-HDMI Glue on other Amlogic SoCs. This adds support for the Glue managing the transceiver, mimicing the init flow provided by Amlogic to setup the ENCL encoder, the glue, the transceiver, the digital D-PHY and the Analog PHY in the proper way. An optional "MEAS" clock can be enabled to measure the delay between each vsync feeding the DW-MIPI-DSI transceiver.
