Subject: [PATCH 08/10] arm64: dts: freescale: s32n79: Add UFS host controller
Date: Wed, 26 Aug 2026 15:40:46 +0200	[thread overview]
Message-ID: <20260826134048.854748-9-larisa.grigore@oss.nxp.com> (raw)
In-Reply-To: <20260826134048.854748-1-larisa.grigore@oss.nxp.com>

Add the S32N79 UFS host controller node to the SoC dtsi, including the
UFSHC register region and the SCM region required for M-PHY
initialization.

The controller remains disabled by default and is enabled by board dts
files as needed.
