Subject: [PATCH 1/2] ARM: mxs: Add serial: Search for specific ocotp nodes
Date: Mon, 9 Oct 2023 14:37:39 -0300 [thread overview]
Message-ID: <20231009173740.3535167-1-festevam@gmail.com> (raw)
From: Fabio Estevam <festevam@denx.de>
Per mxs-ocotp.yaml, "fsl,ocotp" is not a valid entry.
"fsl,ocotp" is only used to indicate the location of the
struct device_node that points to the ocotp node.
Search for the specific "fsl,imx28-ocotp" and "fsl,imx23-ocotp"
instead and remove the undocumented "fsl,ocotp" fallback.
