From mboxrd@z Thu Jan 1 00:00:00 1970 From: arno@natisbad.org (Arnaud Ebalard) Date: Sun, 29 Sep 2013 20:36:41 +0200 Subject: [PATCH, FIX] ARM: mvebu: fix ReadyNAS 102 Power button GPIO to make it active high Message-ID: <87ob7bh3uu.fsf@natisbad.org> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org NETGEAR ReadyNAS 102 Power button definition in .dts file flags associated GPIO active low instead of active high. This results in reversed events reported by input subsystem (0 returned when the button is pressed, 1 when released). This patch makes associated GPIO active high to recover correct behaviour. Signed-off-by: Arnaud Ebalard --- RN102 .dts file sits in Linus tree only since 3.12-rc1 so I guess no one has currently relied on current reversed behaviour, i.e. this can be fixed w/o impact on any userspace program. As a side note, the initial error is mine. arch/arm/boot/dts/armada-370-netgear-rn102.dts | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/arch/arm/boot/dts/armada-370-netgear-rn102.dts b/arch/arm/boot/dts/armada-370-netgear-rn102.dts index 05e4485..396949d 100644 --- a/arch/arm/boot/dts/armada-370-netgear-rn102.dts +++ b/arch/arm/boot/dts/armada-370-netgear-rn102.dts @@ -160,7 +160,7 @@ button at 1 { label = "Power Button"; linux,code = <116>; /* KEY_POWER */ - gpios = <&gpio1 30 1>; + gpios = <&gpio1 30 0>; }; button at 2 { -- 1.8.4.rc3
