This patch divides them in the pins into there respective pin controller nodes. Without this patch serial on StiH416-B2000 Board will not work as it fails with: "st-pinctrl pin-controller-rear.3: failed to get pin(99) name st-pinctrl pin-controller-rear.3: maps: function serial2 group serial2-0 num 4 pinconfig core: failed to register map default (3): no group/pin given" Signed-off-by: Srinivas Kandagatla --- arch/arm/boot/dts/stih416-pinctrl.dtsi | 10 +++++++++- arch/arm/boot/dts/stih416.dtsi | 2 +- 2 files changed, 10 insertions(+), 2 deletions(-) diff --git a/arch/arm/boot/dts/stih416-pinctrl.dtsi b/arch/arm/boot/dts/stih416-pinctrl.dtsi index 957b21a..0f246c9 100644 --- a/arch/arm/boot/dts/stih416-pinctrl.dtsi +++ b/arch/arm/boot/dts/stih416-pinctrl.dtsi @@ -166,6 +166,15 @@ reg = <0x9000 0x100>; st,bank-name = "PIO31"; }; + + serial2-oe { + pinctrl_serial2_oe: serial2-1 { + st,pins { + output-enable = <&PIO11 3 ALT2 OUT>; + }; + }; + }; + }; pin-controller-rear { @@ -218,7 +227,6 @@ st,pins { tx = <&PIO17 4 ALT2 OUT>; rx = <&PIO17 5 ALT2 IN>; - output-enable = <&PIO11 3 ALT2 OUT>; }; }; }; diff --git a/arch/arm/boot/dts/stih416.dtsi b/arch/arm/boot/dts/stih416.dtsi index 3cecd96..1a0326e 100644 --- a/arch/arm/boot/dts/stih416.dtsi +++ b/arch/arm/boot/dts/stih416.dtsi @@ -79,7 +79,7 @@ interrupts = <0 197 0>; clocks = <&CLK_S_ICN_REG_0>; pinctrl-names = "default"; - pinctrl-0 = <&pinctrl_serial2>; + pinctrl-0 = <&pinctrl_serial2 &pinctrl_serial2_oe>; }; /* SBC_UART1 */ -- 1.7.6.5 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
