From 9b63ba37274317520bd8752607476dbcce0f8213 Mon Sep 17 00:00:00 2001 From: Hannes Petermaier Date: Thu, 11 Jun 2015 12:25:43 +0200 Subject: [PATCH] board/BuR/common: support timer5 for pwm-backlight in future we support yet another b&r am335x based board, where Timer 5 is wired to backlight-driver. So we introduce a new driver-type '2' to setup timer5 instead timer6.
