Subject: ARM: dts: imx6q-bx50v3: user-space watchdog GPIO configuration
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=7dd9c42f2668821141690346ca58ecffdaa281f0;p=linux.git

ARM: dts: imx6q-bx50v3: user-space watchdog GPIO configuration

Leave b{4,6}50v3 GPIO expander pca953x pins P05,P10,P11 unconfigured as
they are now used to implement an additional watchdog mechanism in user
space.  P10,P11 pins remain unused (and therefore hogged) on b850v3.
