mfd: arizona: Add device tree binding to specify mono outputs (f199d393) · Commits · 戴 / test

Add device tree bindings to support specifying outputs from the chip as mono outputs. Whilst we are doing it change the out_mono pdata from a bool to an int, because Sparse gets upset about using ARRAY_SIZE on bools. Signed-off-by:
