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.
changes since v5:
- Rebased on tag v6.4.
- Dropped patch 3. Because it depends on the submission of others, it will be
upstream separately later.
patch 1:
- Changed "pwrc_dphy" to "aon_syscon".
- Updated title and description.
patch 2:
- Dropped unnecessary register operations.
- Replaced "pm_runtime_get_sync" with "pm_runtime_resume_and_get".
- Dropped the pm reference on "regulator_enable" error handle.
v5: https://lore.kernel.org/all/[email protected]/
changes since v4:
- Rebased on tag v6.4-rc2.
patch 1:
- Dropped "lane_maps" property.
patch 2:
- Added lane maps in compatible.

- Changed "pwrc_dphy" to "aon_syscon".
v4: https://lore.kernel.org/all/[email protected]/
changes since v3:
- Rebased on tag v6.3-rc4.
patch 1 & patch 3:
- Changed "starfive,aon-syscon" to "power-domains".
- Added "lane_maps" property.
patch 2:
- Changed "STF_DPHY_APBCFGSAIF__SYSCFG(x)" to "STF_DPHY_APBCFGSAIF_SYSCFG(x)".
- 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/[email protected]/
changes since v2:
- Rebased on tag v6.3-rc1.
patch 1:

- Update clocks&resets macros follow patchset [1].
v2: https://lore.kernel.org/all/[email protected]/
changes since v1:
- Rebased on tag v6.2.
- Dropped patch 1, it will be added by the patch [2].
patch 1:
- Changed the node name 'dphy' to 'phy'.
- Changed the "starfive,aon-syscon" description.
- Changed the MIPI DPHY RX IP description.
- Add description to resets.
- Update devicetree binding examples.

StarFive SoCs like the jh7110 use a MIPI D-PHY RX controller based on
a M31 IP. Add a binding for it.
