micrel: add support for KSZ8041RNLI (4bd7b512) · Commits · 戴 / test

Renesas R-Car development boards use KSZ8041RNLI PHY which for some reason has ID of 0x00221537 that is not documented for KSZ8041-family PHYs and does not match the documented ID of 0x0022151x (where 'x' is the revision). We have to add the new #define PHY_ID_* and new ksphy_driver[] entry, almost the same as KSZ8041 one, differing only in the 'phy_id' and 'name' fields. Signed-off-by:
