Subject: [PATCH] ARM: dts: imx7: use 3 PWM cells
Date: Tue, 16 May 2017 00:40:13 -0700 [thread overview]
Message-ID: <20170516074013.3571-1-stefan@agner.ch> (raw)
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.
