Subject: [PATCH v2 3/4] of: base: don't try to read cells_name property if no cells_name set
Date: Fri,  7 Jun 2019 09:32:09 +0200	[thread overview]
Message-ID: <20190607073210.13915-3-linux@rempel-privat.de> (raw)
In-Reply-To: <20190607073210.13915-1-linux@rempel-privat.de>

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.
