Subject: [PATCH v2 6/7] ARM: dts: imx6dl-prtvt7: fix PWM cell count for the backlight node.
Date: Thu, 21 Jan 2021 07:11:40 +0100
Message-ID: <20210121061141.23062-7-o.rempel@pengutronix.de> (raw)
In-Reply-To: <20210121061141.23062-1-o.rempel@pengutronix.de>

At some point PWM cell count was changed, but it didn't triggered any
error, since this DT was overwriting "#pwm-cells".
To make sure, we are in sync with the kernel driver, remove this
property and fix the pwm consumer.
