Subject: arm64: dt: imx8mn: support pwm polarity inversion
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=6bc1e58055c1ea3ff31335637f62a1b77da5633d;p=linux.git

arm64: dt: imx8mn: support pwm polarity inversion

The i.MX8M Nano has the same PWM IP as i.MX6 / i.MX7. This IP
and the driver supporting pwm polarity inversion. Switch CPU
device tree fragment to use 3 pwm-cells.
