Subject: ARM: tegra: apalis-tk1: Activate PWM pin muxing for pwm3
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=e18dc296205fca37dfdc28f10adff93c016d0410;p=openwrt%2Fstaging%2Fblogic.git

ARM: tegra: apalis-tk1: Activate PWM pin muxing for pwm3

Activate PWM pin muxing for Apalis PWM3. Note that the same PWM3 is
already active on pu6 being Apalis BKL1_PWM as well. Therefore exporting
that one for raw sysfs access will fail and one has to revert to using
the PWM backlight.
