From cbb73c1d32e78f942d5d20e4094f8a6413c40772 Mon Sep 17 00:00:00 2001 From: Nick Hainke Date: Thu, 30 Jun 2022 13:16:57 +0200 Subject: [PATCH] arm64: dts: mt7622: fix BPI-R64 WPS button [ Upstream commit c98e6e683632386a3bd284acda4342e68aec4c41 ] The bananapi R64 (BPI-R64) experiences wrong WPS button signals. In OpenWrt pushing the WPS button while powering on the device will set it to recovery mode. Currently, this also happens without any user interaction. In particular, the wrong signals appear while booting the device or restarting it, e.g. after doing a system upgrade. If the device is in recovery mode the user needs to manually power cycle or restart it. The official BPI-R64 sources set the WPS button to GPIO_ACTIVE_LOW in the device tree. This setting seems to suppress the unwanted WPS button press signals. So this commit changes the button from GPIO_ACTIVE_HIGH to GPIO_ACTIVE_LOW. The official BPI-R64 sources can be found on https://github.com/BPI-SINOVOIP/BPI-R64-openwrt Fixes: 0b6286dd96c0 ("arm64: dts: mt7622: add bananapi BPI-R64 board") Suggested-by: INAGAKI Hiroshi Signed-off-by: Nick Hainke Link: https://lore.kernel.org/r/20220630111746.4098-1-vincent@systemli.org Signed-off-by: Matthias Brugger Signed-off-by: Sasha Levin --- arch/arm64/boot/dts/mediatek/mt7622-bananapi-bpi-r64.dts | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/arch/arm64/boot/dts/mediatek/mt7622-bananapi-bpi-r64.dts b/arch/arm64/boot/dts/mediatek/mt7622-bananapi-bpi-r64.dts index 2b9bf8dd14ec..7538918c7a82 100644 --- a/arch/arm64/boot/dts/mediatek/mt7622-bananapi-bpi-r64.dts +++ b/arch/arm64/boot/dts/mediatek/mt7622-bananapi-bpi-r64.dts @@ -49,7 +49,7 @@ wps { label = "wps"; linux,code = ; - gpios = <&pio 102 GPIO_ACTIVE_HIGH>; + gpios = <&pio 102 GPIO_ACTIVE_LOW>; }; };
