Subject: [PATCH v7 5/6] mailbox: imx: populate sub-nodes
Date: Sun, 18 Feb 2024 14:56:17 +0800	[thread overview]
Message-ID: <20240218-imx-mailbox-v7-5-8fb665eeae40@nxp.com> (raw)
In-Reply-To: <20240218-imx-mailbox-v7-0-8fb665eeae40@nxp.com>

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

Some MUs such as i.MX95 MU, have internal SRAM which could be used
for SCMI shared memory, so populate the sub-nodes to use the SRAM.
