Subject: ARM: dts: imx7: use 3 PWM cells
X-Git-Tag: v4.13-rc1~168^2~5^2~29
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=9be48d2d98810ae723c229c05b078ca5a07e9561;p=uclinux-h8%2Flinux.git

ARM: dts: imx7: use 3 PWM cells

The PWM driver has now capability to specify the PWM polarity
which is e.g. for backlight control. Allow to make use of PWM
polarity by specifying pwm-cells to be 3 in the base dt.
