Subject: [PATCH] clk: sunxi: declare OF clock provider
|
|
|
|
Common clock framework allows to register clock providers to get called
|
|
on of_clk_init() by using CLK_OF_DECLARE. This converts sunxi clock
|
|
providers to make use of it and get rid of the mach specific clk init
|
|
call. As sunxi has a bunch of independent clk provider nodes, we hook
|
|
current clock init to board compatible to make it called once.
