From 7264354c0cb8c04bd4a85d24e5d57a0e2417c2fb Mon Sep 17 00:00:00 2001 From: Doug Anderson Date: Mon, 25 Aug 2014 15:59:25 -0700 Subject: pwm: rockchip: Allow polarity invert on rk3288 The rk3288 has the ability to invert the polarity of the PWM. Let's enable that ability. Note that this increases pwm_cells to 3 for rk3288.
