It is a cost-optimized variant of the FRDM-IMX91 board, with notable hardware differences requiring a separate DTS: - 512MB LPDDR4 (FRDM-IMX91 uses 1GB) - 256MB FlexSPI-NAND (FRDM-IMX91 uses 8GB eMMC) - Single GbE port (FRDM-IMX91 has dual GbE) - PMIC PF9453 (FRDM-IMX91 uses PCA9451A) Acked-by: Krzysztof Kozlowski Reviewed-by: Daniel Baluta Signed-off-by: Yanan Yang --- Changes in v3: - add code-review trailers Changes in v2: - Correct author name: removed extra period in "Yanan.Yang" - Refined commit message to clarify board differences --- Documentation/devicetree/bindings/arm/fsl.yaml | 1 + 1 file changed, 1 insertion(+) diff --git a/Documentation/devicetree/bindings/arm/fsl.yaml b/Documentation= /devicetree/bindings/arm/fsl.yaml index 68a2d5fecc43..82f28be401b8 100644 --- a/Documentation/devicetree/bindings/arm/fsl.yaml +++ b/Documentation/devicetree/bindings/arm/fsl.yaml @@ -1412,6 +1412,7 @@ properties: items: - enum: - fsl,imx91-11x11-evk # i.MX91 11x11 EVK Board + - fsl,imx91-11x11-frdm-s # FRDM-IMX91S Board - const: fsl,imx91 =20 - description: i.MX93 based Boards --=20 2.43.0
