The existing bootph binding is defined such that properties in a subnode are also implied in the supernode also, as in this example:
buttons { /* bootph,pre-ram is implied by btn1 */ compatible = "gpio-keys"; btn1 { bootph,pre-ram; gpios = <&gpio_a 3 0>; label = "button1"; linux,code = <BTN_1>; }; Provide an option to implement this in fdtgrep.
