From c5a28380257327bb7b89974919a3695047277ba5 Mon Sep 17 00:00:00 2001 From: Codrin Ciubotariu Date: Fri, 15 May 2020 17:00:01 +0300 Subject: [PATCH] ARM: dts: at91: Configure I2C SCL gpio as open drain The SCL gpio pin used by I2C bus for recovery needs to be configured as open drain. Fixes: 455fec938bbb ("ARM: dts: at91: sama5d2: add i2c gpio pinctrl") Fixes: a4bd8da893a3 ("ARM: dts: at91: sama5d3: add i2c gpio pinctrl") Fixes: 8fb82f050cf6 ("ARM: dts: at91: sama5d4: add i2c gpio pinctrl") Signed-off-by: Codrin Ciubotariu Link: https://lore.kernel.org/r/20200515140001.287932-1-codrin.ciubotariu@microchip.com Signed-off-by: Alexandre Belloni --- arch/arm/boot/dts/at91-sama5d2_ptc_ek.dts | 6 +++--- arch/arm/boot/dts/at91-sama5d2_xplained.dts | 8 ++++---- arch/arm/boot/dts/sama5d3.dtsi | 6 +++--- arch/arm/boot/dts/sama5d4.dtsi | 6 +++--- 4 files changed, 13 insertions(+), 13 deletions(-) diff --git a/arch/arm/boot/dts/at91-sama5d2_ptc_ek.dts b/arch/arm/boot/dts/at91-sama5d2_ptc_ek.dts index 45c671a2bcf2..c894c7c788a9 100644 --- a/arch/arm/boot/dts/at91-sama5d2_ptc_ek.dts +++ b/arch/arm/boot/dts/at91-sama5d2_ptc_ek.dts @@ -182,7 +182,7 @@ pinctrl-0 = <&pinctrl_i2c0_default>;
