Make it usable for KSZ9477 and KSZ8830 variants. - use ksz_rmw8() in ksz9477_drive_strength_write() changes v2: - make it work on all know KSZ* variants except of undocumented LAN* switches - add io-drive-strength compatible for ksz88xx chips - test exact drive strength instead of nearest closest. - add comment and refactor the code Oleksij Rempel (2): dt-bindings: net: dsa: microchip: Update ksz device tree bindings for drive strength net: dsa: microchip: Add drive strength configuration .../bindings/net/dsa/microchip,ksz.yaml | 20 ++ drivers/net/dsa/microchip/ksz8795_reg.h | 14 - drivers/net/dsa/microchip/ksz9477_reg.h | 13 - drivers/net/dsa/microchip/ksz_common.c | 309 ++++++++++++++++++ drivers/net/dsa/microchip/ksz_common.h | 20 ++ 5 files changed, 349 insertions(+), 27 deletions(-)
