From 96d5a545374eac8fbd29b23bcd0d624c37e0ab9d Mon Sep 17 00:00:00 2001 From: Franklin S Cooper Jr Date: Tue, 3 May 2016 10:56:48 -0500 Subject: ARM: dts: am437x: Add missing compatibles to PWM binding documents There are several SOC specific compatibles for ECAP, EHRPWM and PWMMS that are in use but aren't properly documented. Therefore, fix this by adding the compatibles to the appropriate binding documents. While at it make minor corrections to the binding document.
