Subject: [PATCH v5 0/2] Add motorcomm phy pad-driver-strength-cfg support
The motorcomm phy (YT8531) supports the ability to adjust the drive
strength of the rx_clk/rx_data, and the default strength may not be
suitable for all boards. So add configurable options to better match
the boards.(e.g. StarFive VisionFive 2)
The first patch adds a description of dt-bingding, and the second patch adds
YT8531's parsing and settings for pad-driver-strength-cfg.
Changes since v4:
Patch 1:
- Removed register-related DS(3b) values and added vol descriptions (by Andrew Lunn)
- Dropped the type and added '-microamp' suffix. (by Rob Herring)
Patch 2:
- Return -EINVAL if the value in DT but it is invalid (by Andrew Lunn)
Changes since v3:
Patch 1:
- Used current values instead of register values
- Added units and numerical descriptions of driver-strength
Patch 2:
- Added a lookup table to listing the valid values in the schema (by Andrew Lunn)
Changes since v2:
Patch 2:
- Readjusted the order of YT8531_RGMII_xxx to below YTPHY_PAD_DRIVE_STRENGTH_REG (by Frank Sae)
- Reversed Christmas tree, sort these longest first, shortest last (by Andrew Lunn)
- Rebased on tag v6.4
Changes since v1:
Patch 1:
- Renamed "rx-xxx-driver-strength" to "motorcomm,rx-xxx-driver-strength" (by Frank Sae)
Patch 2:
- Added default values for rxc/rxd driver strength (by Frank Sea/Andrew Lunn)
- Added range checking when val is in DT (by Frank Sea/Andrew Lunn)
