Subject: [PATCH v5 0/3] Add JH7110 MIPI DPHY RX support

This patchset adds mipi dphy rx driver for the StarFive JH7110 SoC.
It is used to transfer CSI camera data. The series has been tested on
the VisionFive 2 board.

This patchset should be applied after the patchset [1] [2]:

changes since v4:
- Rebased on tag v6.4-rc2.

patch 1:
- Dropped "lane_maps" property.

patch 2:
- Added lane maps in compatible.

patch 3:
- Dropped "lane_maps" property.
- Changed "pwrc_dphy" to "aon_syscon".

v4: https://lore.kernel.org/all/20230412084540.295411-1-changhuang.liang@starfivetech.com/

changes since v3:
- Rebased on tag v6.3-rc4.

patch 1 & patch 3:
- Changed "starfive,aon-syscon" to "power-domains".

- Merged phy_init into phy_power_on.
- Merged phy_exit into phy_power_off.
- Replaced syscon with power domain framework.
- Parsed "lane_maps" property form device tree.
- Dropped compatible private data.

v3: https://lore.kernel.org/all/20230315100421.133428-1-changhuang.liang@starfivetech.com/
