Subject: [PATCH v1 1/2] pinctrl: ocelot: add pwm output option for LAN966x
Date:   Sat, 26 Mar 2022 20:28:47 +0100
Message-Id: <20220326192848.2944519-1-michael@walle.cc>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

According to the reference manual, you can mux the PWM output on GPIO27
and GPIO51. This was missing in the pinmux table. Add it.

Tested on a LAN9668 on GPIO51.
