I'm guessing the following were copied from clk-sunxi.c.

clk_register_clkdev() is not used in this file, so not needed.

A remnant of the USB clocks, which has been moved to clk-usb.c. Not needed here nor in clk-sunxi.c.

+#include <linux/spinlock.h> +#include <linux/log2.h>Is this used?
This is only used for clock factor calculation. Not applicable in clk-simple-gates.c, so no.

Not sure why our critical clocks lists are __initdata...
