I will do so in the device-tree series that I will post once the bindings and driver patches get merged. The v2 series for the bindings and driver patches that I am referring to is at: https://lore.kernel.org/r/20230116085534.440820-1-s-vadapalli@ti.com/ Regards, Siddharth. _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
