Subject: [PATCH v3 4/5] arm64: dts: exynosautov9: prepare usi0 changes
Date: Fri, 1 Jul 2022 10:52:25 +0900 [thread overview]
Message-ID: <20220701015226.32781-5-chanho61.park@samsung.com> (raw)
In-Reply-To: <20220701015226.32781-1-chanho61.park@samsung.com>
Before adding whole USI nodes, this applies the changes of usi0 in
advance. To be the usi0 and serian_0 nodes as SoC default, some
properties should be moved to exynosautov9-sadk.dts.
