Subject: [PATCH 03/15] serial: ns16550: rpi: remove ungating now done by proper clk driver
Date: Thu,  5 May 2022 10:01:40 +0200	[thread overview]
Message-ID: <20220505080152.1068424-4-a.fatoum@pengutronix.de> (raw)
In-Reply-To: <20220505080152.1068424-1-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.
