From 4a0a1fc91c4f28e431fa52ba009f2852acbfe07d Mon Sep 17 00:00:00 2001 From: Michal Cieslakiewicz Date: Sun, 22 Dec 2019 21:51:48 +0100 Subject: [PATCH] mac80211: ath9k: add GPIO mask dts property This patch adds 'qca,gpio-mask=' device tree property to ath9k node. This optional setting is a hack and should only be used in very special (and rare) cases when a button or LED is wired to a GPIO pin normally masked out (due to being one-way etc). Netgear WNDR4300 v2 is one such example - it uses GPI9 for RFKILL. See ath9k/reg.h *_GPIO_MASK constants. Use with caution and expect to see stream of kernel warnings if wrong mask value is provided.
