Subject: [PATCH 2/4] arm64: dts: apple: Add ADMAC resets on t8103/t600x
Date: Sun, 18 Sep 2022 11:58:43 +0200	[thread overview]
Message-ID: <20220918095845.68860-3-povik+lin@cutebit.org> (raw)
In-Reply-To: <20220918095845.68860-1-povik+lin@cutebit.org>

There's a shared reset for the ADMAC and MCA peripherals. The MCA node
already describes it, and being a shared reset it is important we
describe it on the ADMAC node too.
