From 133ace3f38045968b971b3ac62da495c54de49a6 Mon Sep 17 00:00:00 2001 From: Simon Horman Date: Tue, 2 May 2017 12:30:24 +0200 Subject: arm64: dts: ulcb: Set drive-strength for ravb pins MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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. Based on: * commit 7d73a4da2681 ("arm64: dts: r8a7795: salvator-x: Set drive-strength for ravb pins") * commit 4903987033be ("arm64: dts: r8a7796: salvator-x: Set drive-strength for ravb pins") Cc: Geert Uytterhoeven Cc: Niklas Söderlund Signed-off-by: Simon Horman Reviewed-by: Geert Uytterhoeven --- arch/arm64/boot/dts/renesas/ulcb.dtsi | 18 ++++++++++++++++-- 1 file changed, 16 insertions(+), 2 deletions(-) (limited to 'arch/arm64/boot/dts/renesas/ulcb.dtsi') diff --git a/arch/arm64/boot/dts/renesas/ulcb.dtsi b/arch/arm64/boot/dts/renesas/ulcb.dtsi index 2bc7ceb2efa4..41e83c8530f7 100644 --- a/arch/arm64/boot/dts/renesas/ulcb.dtsi +++ b/arch/arm64/boot/dts/renesas/ulcb.dtsi @@ -198,8 +198,22 @@ pinctrl-names = "default"; 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>; + }; }; i2c2_pins: i2c2 { -- cgit v1.2.3
