From 65878b126c8f2d761273241cf778b1c6aa50c500 Mon Sep 17 00:00:00 2001 From: Kevin Hilman Date: Tue, 30 May 2017 18:21:25 -0700 Subject: ARM: dts: da850-evm: fix tca6416 for use with GPIO hogs In order GPIOS from this controller to be used with the "gpio-hogs" property, the tca6416 node has to properly labeled as a gpio-controller, and use #gpio-cells. With that, the SEL_A, SEL_B, SEL_C lines that are used to select VPIF input can be configured using GPIO hogs. As an example, example, the configuration below selects the analog video input on the da850-evm UI board: &tca6416 { status = "okay"; sel_a { gpio-hog; gpios = <7 GPIO_ACTIVE_HIGH>; output-high; line-name = "ADC_ENn"; }; sel_b { gpio-hog; gpios = <6 GPIO_ACTIVE_HIGH>; output-high; line-name = "CAMERA_ENn"; }; sel_c { gpio-hog; gpios = <5 GPIO_ACTIVE_HIGH>; output-low; line-name = "VIDEO_IN_ENn"; }; }; Signed-off-by: Kevin Hilman Signed-off-by: Sekhar Nori --- arch/arm/boot/dts/da850-evm.dts | 2 ++ 1 file changed, 2 insertions(+) (limited to 'arch/arm/boot/dts/da850-evm.dts') diff --git a/arch/arm/boot/dts/da850-evm.dts b/arch/arm/boot/dts/da850-evm.dts index 8d244cd76c36..a423e8ebfb37 100644 --- a/arch/arm/boot/dts/da850-evm.dts +++ b/arch/arm/boot/dts/da850-evm.dts @@ -82,6 +82,8 @@ tca6416: gpio@20 { compatible = "ti,tca6416"; reg = <0x20>; + gpio-controller; + #gpio-cells = <2>; }; }; wdt: wdt@21000 { -- cgit v1.2.3-59-g8ed1b
