[PATCH v3 2/3] of: base: don't try to read cells_name property if no cells_name set

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Oleksij Rempel <linux@xxxxxxxxxxxxxxxx>

Some device tree node parsed by of_count_phandle_with_args() have no #*-cells
parameter. To make linux device trees work with barebox, we should accept
cells_name set to NULL, so sync this behavior with linux.
