From f998540e80baa20f5248f94bb78f414bd3eaedc1 Mon Sep 17 00:00:00 2001 From: John Crispin Date: Fri, 26 Feb 2016 08:35:35 +0000 Subject: [PATCH] ramips: fix GPIO names for RT5350F-OLinuXino-EVB Hi, the board in subject (RT5350F-OLinuXino-EVB) still ships from vendor with a RC3 image built upon a .dts file which declares GPIO12 and GPIO14 as relay2 and relay1 respectively, as you can see from their rt5350f branch on GitHub. For some reason in the official stable build both the GPIOs are swapped and the wrong names are declared in the gpio-export directive. I'm submitting this patch which should roll back the wrong changes, so that we get backward compatibility with any script developed on RC3 which controls the relays. After patching correct operation is restored: root@OpenWrt:/# cat /sys/kernel/debug/gpio GPIOs 0-21, platform/10000600.gpio, 10000600.gpio: gpio-0 (button ) in hi gpio-12 (relay2 ) out lo gpio-14 (relay1 ) out lo Thank you, Signed-off-by: Lorenzo Cafaro SVN-Revision: 48796 --- target/linux/ramips/dts/RT5350F-OLINUXINO-EVB.dts | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) diff --git a/target/linux/ramips/dts/RT5350F-OLINUXINO-EVB.dts b/target/linux/ramips/dts/RT5350F-OLINUXINO-EVB.dts index 8c15a7836b7..8d32230533d 100644 --- a/target/linux/ramips/dts/RT5350F-OLINUXINO-EVB.dts +++ b/target/linux/ramips/dts/RT5350F-OLINUXINO-EVB.dts @@ -83,15 +83,15 @@ #size-cells = <0>; relay1 { - gpio-export,name = "gpio12"; + gpio-export,name = "relay1"; gpio-export,output = <0>; - gpios = <&gpio0 12 0>; + gpios = <&gpio0 14 0>; }; relay2 { - gpio-export,name = "gpio14"; + gpio-export,name = "relay2"; gpio-export,output = <0>; - gpios = <&gpio0 14 0>; + gpios = <&gpio0 12 0>; }; button { -- 2.30.2
