From 57dfd17edaf353d0880bea494be05e8cda82ebc0 Mon Sep 17 00:00:00 2001 From: Laxman Dewangan Date: Wed, 22 Jun 2016 17:17:22 +0530 Subject: [PATCH] dt-bindings: pwm: tegra: Add compatible string for Tegra186 Tegra186 has 8 different PWM controllers and each controller has only one output. Earlier SoC generations have 4 PWM outputs per controller. Add a device tree compatible string for Tegra186 to be able to differentiate between the two.
