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 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) Previous versions: v1 - https://patchwork.kernel.org/project/netdevbpf/cover/20230426063541.15378-1-samin.guo@starfivetech.com Samin Guo (2): dt-bindings: net: motorcomm: Add pad driver strength cfg net: phy: motorcomm: Add pad drive strength cfg support .../bindings/net/motorcomm,yt8xxx.yaml | 12 +++++ drivers/net/phy/motorcomm.c | 46 +++++++++++++++++++ 2 files changed, 58 insertions(+) base-commit: d3e1ee0e67e7603d36f4fa2fec6b881c01aabe89 -- 2.17.1
