[PATCH v2 1/3] dt-bindings: arm: ti: Add bindings for Variscite VAR-SOM-AM62P

[Stefano Radaelli]

Hi Krzysztof,

Thank you for your suggestion. Actually, our compatible strings for
Variscite SOMs follow the format "som-factor"-"processor". Here are
some examples:

https://github.com/varigit/linux-imx/blob/lf-6.6.y_6.6.52-2.2.0_var01/arch/arm64/boot/dts/freescale/imx93-var-som.dtsi#L14
https://github.com/varigit/linux-imx/blob/lf-6.6.y_6.6.52-2.2.0_var01/arch/arm64/boot/dts/freescale/imx8mp-var-som.dtsi#L15
https://github.com/varigit/linux-imx/blob/lf-6.6.y_6.6.52-2.2.0_var01/arch/arm64/boot/dts/freescale/imx91-var-som.dtsi#L14

These strings are used in our Yocto filesystem for WiFi management and
other applications. Changing them would require updating the entire
Yocto configuration.

Best regards,
Stefano
