From dd1d420f40e75c3881a04001e6f2798492ee83c2 Mon Sep 17 00:00:00 2001 From: Nick Hainke Date: Thu, 30 Jun 2022 12:32:20 +0200 Subject: [PATCH] arm64: dts: mt7622: fix BPI-R64 WPS button 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 --- arch/arm64/boot/dts/mediatek/mt7622-bananapi-bpi-r64.dts | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) --- a/arch/arm64/boot/dts/mediatek/mt7622-bananapi-bpi-r64.dts +++ b/arch/arm64/boot/dts/mediatek/mt7622-bananapi-bpi-r64.dts @@ -54,7 +54,7 @@ wps { label = "wps"; linux,code = ; - gpios = <&pio 102 GPIO_ACTIVE_HIGH>; + gpios = <&pio 102 GPIO_ACTIVE_LOW>; }; };
