Subject: [PATCH 3/4] soc: bcm: brcmstb: biuctrl: Update layout for A72 on 7211
Date: Tue, 10 Dec 2019 15:30:42 -0800	[thread overview]
Message-ID: <20191210233043.15193-4-f.fainelli@gmail.com> (raw)
In-Reply-To: <20191210233043.15193-1-f.fainelli@gmail.com>

The BIUCTRL layout is a little different on 7211 which is equipped with
a Cortex-A72, account for those register offset differences. We will
match 7211 specifically in a subsequent commit.
