The board embeds an audio codec IC, Cirrus CS42L73. While there is no in-tree driver for it, we need a binding to describe how it is wired in the board, e.g. for IRQ/RESET lines. Following Linux binding for the same IC, create one in dts/bindings/sound. Note that Linux binding is less complete/outdated.
