TDA4VEN-Q1: Device Tree TI language extension

Part Number: TDA4VEN-Q1

Tool/software:

Dear TI team, 

I am working on a device tree customization for J722S SoC.

I have found "bootph-*" overlay property in dtsi files and as far as I know it is related to Texas Instruments only device trees because it is not in Device Tree specification.

Thus it looks that TI uses the standard device tree syntax but with and extended set of attributes. I suspect I will find some other TI related attributes.

Could you let me know where to find documentation about this and other TI specific attributes?.

Many thanks in advanced.

Gilles.

    Gilles,

    All the device tree bindings are documented in the Linux kernel Documentation folder. 

    The bootph* is for U-Boot specifically. So it should be under U-Boot documentation. Also this is not specific to TI but more for U-Boot.

    Regards,
