From 7eb3f6ffb5c3635e8cc5df7b19741b4bfc5894f5 Mon Sep 17 00:00:00 2001 From: Alexander Shiyan Date: Wed, 12 Mar 2014 19:53:05 +0400 Subject: pwm: Add CLPS711X PWM support Add a new driver for the ARM CLPS711X Pulse Width Modulator (PWM) interface. This CPU contain two 4-bit PWM outputs with constant period, based on CPU PLL frequency. PWM polarity is determined by hardware by power on reset.
