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. --- V3: - Sort out the bindings compatible 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 Clément Léger (6): net: pcs: rzn1-miic: add pcs_early_setup() function net: stmmac: add support to use a generic phylink_pcs as PCS net: stmmac: add support to provide pcs from platform data dt-bindings: net: renesas,rzn1-gmac: Document RZ/N1 GMAC support net: stmmac: add support for RZ/N1 GMAC ARM: dts: r9a06g032: describe GMAC1 .../bindings/net/renesas,rzn1-gmac.yaml | 67 ++++++++++ arch/arm/boot/dts/r9a06g032.dtsi | 18 +++ drivers/net/ethernet/stmicro/stmmac/Kconfig | 11 ++ drivers/net/ethernet/stmicro/stmmac/Makefile | 1 + drivers/net/ethernet/stmicro/stmmac/common.h | 2 + .../net/ethernet/stmicro/stmmac/dwmac-rzn1.c | 120 ++++++++++++++++++ .../net/ethernet/stmicro/stmmac/stmmac_main.c | 8 +- .../net/ethernet/stmicro/stmmac/stmmac_mdio.c | 1 + drivers/net/pcs/pcs-rzn1-miic.c | 12 ++ include/linux/pcs-rzn1-miic.h | 3 + include/linux/stmmac.h | 1 + 11 files changed, 240 insertions(+), 4 deletions(-) create mode 100644 Documentation/devicetree/bindings/net/renesas,rzn1-gmac.yaml create mode 100644 drivers/net/ethernet/stmicro/stmmac/dwmac-rzn1.c
