Describe the two Marvell 88Q2110/QFN40 PHYs available on the R-Car V4H White Hawk RAVB/Ethernet(1000Base-T1) sub-board. The two PHYs are wired up on the board by default, there is no need to move any resistors which are needed to access other PHYs available on this sub-board. Signed-off-by: Niklas Söderlund <niklas.soderlund+renesas@ragnatech.se> --- * Changes since v2 - Fix spelling in commit message. - Add pinconf for link pin for both AVBs. - Rename the phy node to make it clear which AVB it relates too. - Add aliases for ethernet1 and ethernet2 so U-Boot can set MAC addresses. - Rebase to reflect updated of filename for white-hawk-ethernet.dtsi. * Changes since v1 - Correct typo in commit s/adv1/avb1/. - Do not use underscores in node names. - Move the MDIO bus properties into a septate child mdio node. This change depends on updates to the driver and bindings posted separately. --- .../boot/dts/renesas/white-hawk-ethernet.dtsi | 103 ++++++++++++++++++ 1 file changed, 103 insertions(+)
