Subject: [PATCH v2 0/2] phy: mtk-mipi-csi: add driver for CSI phy

Adding a new driver for the MIPI CSI CD-PHY module v 0.5 embedded in
some Mediatek soc, such as the MT8365

This driver was adapted from https://patchwork.kernel.org/project/linux-mediatek/cover/20200708104023.3225-1-louis.kuo@mediatek.com/

v1 can be found here: https://lore.kernel.org/all/20230403071929.360911-1-jstephan@baylibre.com/

Changelog
Changes in v2:
	- fix all comments on bindings
	- move the binding chunk from driver to binding commit
	- fix dt_binding_check error (reported by DT_CHECKER_FLAGS)
	- use a more generic compatible string
	- add a new dt properties to simplify the driver
	  "mediatek,is_cdphy"
	- rename the driver and the corresponding file to include
	  version
	- drop of_match_ptr()
	- use devm_platform_ioremap_resource
	- use phy-mtk-io.h api instead of regmap
	- rework the driver to use dt nodes to declare PHY instead of an
	  array in the driver
	- remove useless define for unused registers
	- remove support for CSI0A/B because it cannot be tested, and it
	  simplifies the driver for a first review
	- edit commit message and bindings to be more descriptive about the
	  hardware
