While the former uses the same MIPI D-PHY that is already supported for DSI, the latter embeds its own D-PHY. In order to distinguish the use of the D-PHY between Rx mode (for MIPI CSI-2) and Tx mode (for MIPI DSI), a submode is introduced for D-PHY in the PHY API. This allows adding Rx support in the A31 D-PHY driver. A few changes and fixes are applied to the A31 CSI controller driver, in order to support the MIPI CSI-2 use-case. Changes since v1: - reworked fwnode and media graph on the CSI controller end to have one port per interface, which solves the bus type representation issue; - removed unused IRQ handlers in the MIPI CSI-2 bridges; - avoided the use of devm_regmap_init_mmio_clk; - deasserted reset before enabling clocks; - fixed reported return code issues (ret |=, missing checks); - applied requested cosmetic changes (backward goto, etc); - switched over to runtime PM for the mipi csi-2 bridge drivers; - selected PHY_SUN6I_MIPI_DPHY in Kconfig for sun6i-mipi-csi2; - registered nodes with mipi csi-2 bridge subdevs; - used V4L2 format info instead of switch/case for sun6i-csi bpp; - fixed device-tree bindings as requested (useless properties, license); - fixed mipi bridge dt instances names; - added PHY API documentation about mode/power on order requirement; - fixed clock error return code in d-phy code; - fixed D-PHY mode check in d-phy code; - added MAINTAINERS entries for the new drivers; - added V4L2 compliance results; - added various comments and rework commit mesages as requested.
