From 9d7e72858d9d84abbbb49e98e2dafeee2f7fd9b6 Mon Sep 17 00:00:00 2001 From: Fabrizio Castro Date: Wed, 20 Dec 2017 11:15:43 +0000 Subject: dt-bindings: pwm: rcar: Document r8a774[35] PWM bindings This patch adds compatible strings specific to r8a774[35], no driver change is needed as the fallback compatible string will activate the right code. Also, this patch replaces the example with a DT snippet used for adding PWM0 support to an r8a7743 based platform as the r8a7743 is now the first platform fully compatible with this driver and its PWM DT nodes refer to up-to-date code.
