Subject: [PATCH] clk: sunxi: add clock-output-names dt property support
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
sunxi clock drivers use dt node name as clock name, but clock
nodes should be named clk@X, so the names would be the same.
Let the drivers read clock names from dt clock-output-names
property.
