Subject: [PATCH 10/15] clocksource: bcm2835: bump below architeced timer for AArch64
Date: Thu,  5 May 2022 10:01:47 +0200	[thread overview]
Message-ID: <20220505080152.1068424-11-a.fatoum@pengutronix.de> (raw)
In-Reply-To: <20220505080152.1068424-1-a.fatoum@pengutronix.de>

We use the ARM architected timer on other ARMv8 platforms as well, so
let's do the same for the 64-bit Raspberry Pi configuration.
