[PATCH net-next v2 0/6] net: stmmac: add renesas,rzn1-gmac support

From: Clément Léger
Date: Wed Feb 08 2023 - 11:40:36 EST


The rzn1-gmac instance is connected to a PCS (MIIC). In order to use
this pcs, add support in the sttmac driver to set a generic phylink pcs
device instead of the xpcs only. Moreover, it adds support to provide
a phylink pcs device from the stmmac platform data and use it with the
driver. It also adds the bindings and the new rzn1-gmac driver that
retrieve this pcs from the device-tree.

V2:
- Remove patch that moves phylink_start() earlier in init
- Add miic_early_qsetup() which allows initializing some miic port
earlier to provide a RX clock to stmmac IP
- Call miic_early_setup() in rzn1 stmmac driver
- Fix bindings
