Some Broadcom PHYs are capable to operate in simplified MII mode, without TXER, RXER, CRS and COL signals as defined for the MII. The MII-Lite mode can be used on most Ethernet controllers with full MII interface by just leaving the input signals (RXER, CRS, COL) inactive. The absence of COL signal makes half-duplex link modes impossible but does not interfere with BroadR-Reach link modes on Broadcom PHYs, because they are all full-duplex only. Add MII-Lite interface mode, especially for Broadcom two-wire PHYs. Signed-off-by: Kamil Horák - 2N <redacted> Reviewed-by: Maxime Chevallier <maxime.chevallier@bootlin.com>
