From ff993defdbf31404cf08089c27023f26ed767e61 Mon Sep 17 00:00:00 2001 From: blogic Date: Fri, 26 Feb 2016 08:35:35 +0000 Subject: [PATCH 1/1] 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 git-svn-id: svn://svn.openwrt.org/openwrt/trunk@48796 3c298f89-4303-0410-b956-a3cf2f4a3e73 --- 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 8c15a7836b..8d32230533 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 { -- 2.11.0
