Subject: [PATCH] clk: sunxi: support better factor DT nodes
|

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.
