Subject: [PATCH v4 1/4] dt-bindings: soc: imx8m: add DT Binding doc for soc unique ID
Date: Fri, 20 Nov 2020 18:11:09 +0800 [thread overview]
Message-ID: <20201120101112.31819-1-alice.guo@nxp.com> (raw)
Add DT Binding doc for the Unique ID of i.MX 8M series.
v2: remove the subject prefix "LF-2571-1"
v3: put it into Documentation/devicetree/bindings/arm/fsl.yaml
modify the description of nvmem-cells
use "make ARCH=arm64 dtbs_check" to test it and fix errors
v4: use allOf to limit new version DTS files for i.MX8M to include
"fsl,imx8mm/n/p/q-soc", nvmem-cells and nvmem-cells-names
Signed-off-by: Alice Guo <alice.guo@nxp.com>
