Subject: [PATCH v2 09/21] serial: ns16550: rpi: remove ungating now done by proper clk driver
Date: Thu,  9 Jun 2022 07:59:10 +0200	[thread overview]
Message-ID: <20220609055922.667016-10-a.fatoum@pengutronix.de> (raw)
In-Reply-To: <20220609055922.667016-1-a.fatoum@pengutronix.de>

We have bcm2835-aux-clk driver that will take care to ungate the clock,
so we can remove this Raspberry Pi 3 specific detail from the driver.

Tested on Raspberry Pi 3b.
