Subject: [PATCH] pwm: atmel: Remove platform_device_id and use only dt bindings
Date:   Wed, 18 Sep 2019 16:05:34 +0200
Message-Id: <20190918140534.23365-1-kamel.bouhara@bootlin.com>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Since commit 26202873bb51 ("avr32: remove support for AVR32
architecture") there is no more user of platform_device_id and we
should only use dt bindings
