From 4db3926874a6a17cca1f97a4fd92e58e9182a272 Mon Sep 17 00:00:00 2001 From: "Arnaud Patard (Rtp)" <arnaud.patard@rtp-net.org> Date: Fri, 5 Mar 2021 11:27:51 +0100 Subject: [PATCH] rockchip: pwm: Fix default polarity In the code, the default polarity is set to positive/positive, which is neither normal polarity or inverted polarity. It's only the hardware default. This leads to booting linux with wrong polarity setting. Update the code to use PWM_DUTY_POSTIVE | PWM_INACTIVE_NEGATIVE by default instead.
