Subject: [PATCH v2 2/4] pwm: Drop of_pwm_simple_xlate() in favour of of_pwm_xlate_with_flags()
Date: Mon, 10 May 2021 16:06:38 +0200	[thread overview]
Message-ID: <20210510140640.980100-3-u.kleine-koenig@pengutronix.de> (raw)
In-Reply-To: <20210510140640.980100-1-u.kleine-koenig@pengutronix.de>

Since the previous commit the latter function can do everything that the
former does. So simplify accordingly.
