From: Tim Harvey Date: Fri, 8 Sep 2017 18:56:59 +0000 (-0700) Subject: cns3xxx: fix GPIO controller interrupt enable X-Git-Tag: v18.06.0-rc1~2274 X-Git-Url: http://git.openwrt.org/?p=openwrt%2Fopenwrt.git;a=commitdiff_plain;h=79366b81945d38ce1afd0bca867a0a457e0605f9 cns3xxx: fix GPIO controller interrupt enable The cns3xxx interrupt controller uses a single register and as such the 'mask' reg/functions must be used as opposed to the 'enable'/'disable' reg/functions. This fixes an issue that occurs if more than one GPIO on a specific controller (there is GPIOA and GPIOB each having 32 GPIO's) uses interrupts. When one would get enabled all others would be disabled prior to this patch.
