From 9be48d2d98810ae723c229c05b078ca5a07e9561 Mon Sep 17 00:00:00 2001 From: Stefan Agner Date: Tue, 16 May 2017 00:40:13 -0700 Subject: [PATCH] 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.
