Subject: [PATCH v2 2/9] arm64: dts: imx8ulp: Add I3C2 controller node
Date: Mon, 20 Jul 2026 22:12:10 +0800	[thread overview]
Message-ID: <20260720-imx8ulp-dts-v2-2-d05c67676f53@nxp.com> (raw)
In-Reply-To: <20260720-imx8ulp-dts-v2-0-d05c67676f53@nxp.com>

From: Peng Fan <peng.fan@nxp.com>

Add the I3C2 (i3c-master@29360000) node to the imx8ulp device tree using
the Silvaco I3C master IP. Configure PCC3-gated clock with SOSC DIV2 as
parent at 24 MHz for pclk and fast_clk. slow_clk uses a dummy clock.
