The EthernetAVB should not depend on the bootloader to setup correct drive-strength values. Values for drive-strength where found by examining the registers after the bootloader has configured the registers and successfully used the EthernetAVB.
Signed-off-by: Niklas Söderlund <[email protected]> --- Changes since v1: - Only set drive-strength for output pins, thanks Geert. - Add all used pin groups to the mux section. arch/arm64/boot/dts/renesas/r8a7795-salvator-x.dts | 18 ++++++++++++++++-- 1 file changed, 16 insertions(+), 2 deletions(-) diff --git a/arch/arm64/boot/dts/renesas/r8a7795-salvator-x.dts b/arch/arm64/boot/dts/renesas/r8a7795-salvator-x.dts index b1eab68..784ced9 100644 --- a/arch/arm64/boot/dts/renesas/r8a7795-salvator-x.dts +++ b/arch/arm64/boot/dts/renesas/r8a7795-salvator-x.dts @@ -225,8 +225,22 @@ }; avb_pins: avb { - groups = "avb_mdc"; - function = "avb"; + mux { + groups = "avb_link", "avb_phy_int", "avb_mdc", + "avb_mii"; + function = "avb"; + }; + + pins_mdc { + groups = "avb_mdc"; + drive-strength = <24>; + }; + + pins_mii_tx { + pins = "PIN_AVB_TX_CTL", "PIN_AVB_TXC", "PIN_AVB_TD0", + "PIN_AVB_TD1", "PIN_AVB_TD2", "PIN_AVB_TD3"; + drive-strength = <12>; + }; }; du_pins: du { -- 2.10.2
