patches.renesas/0375-ARM-shmobile-kota2-Use-leds-pwm-pwm-rmob.patch

From 8fa9b9d29518469fd9d401be2888339b04259f77 Mon Sep 17 00:00:00 2001
From: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>
Date: Tue, 16 Jul 2013 12:32:06 +0200
Subject: ARM: shmobile: kota2: Use leds-pwm + pwm-rmob

Instead of using the LED-specific TPU PWM driver, switch to the generic
TPU PWM driver with leds-pwm.
