[PATCH net-next v3 0/3] Add support for VSC8531_02 PHY and DT RGMII tuning

[Harini Katakam]

Add support for VSC8531_02 PHY ID.
Also provide an option to change RGMII delay value via devicetree.

v3 changes:
- Remove patch 2/3 from v2 as custom mscc properties dont need to be
defined. rx-internal-delay-ps and tx-internal-delay-ps can be used.
- Change RGMII delay precedence as advised by Vladimir:
 phy-mode                       rgmii                          rgmii-rxid/rgmii-id
 --------------------------------------------------------------------------------------------
 rx-internal-delay-ps absent    0.2 ns                         2 ns
 rx-internal-delay-ps present   follow rx-internal-delay-ps    follow rx-internal-delay-ps
- Split VSC8531-02 and RGMII delay config into separate patches.
- Correct vendor ID
- Update commit description and subject everywhere to say RGMII delays
instead of RGMII tuning.

v2 changes:
- Added patch to use a common vendor phy id match
- Removed dt include header patch because delays should be specied in
ps, not register values
- Updated DT binding description and commit for optional delay tuning to
be clearer on the precedence
- Updated dt property name to include vendor instead of phy device name
- Switch both VSC8531 and VSC8531-02 to use exact phy id match as they
share the same model number
- Ensure RCT
- Improve optional property read
