Subject: [PATCH] clk: sunxi: support better factor DT nodes
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The DT nodes should look like
abc_clk: clk@deadbeef {
...
clock-output-names = "abc";
}
But our old DT nodes look like
abc: abc@deadbeef {
...
}
So, let's support both formats, until we can transition everything
to the new, correct one.
