[PATCH 1/2] clk: sunxi: Add support for the usb-clk on sun8i a23 and a33 SoCs

[Hans de Goede]

The usb-clk on sun8i a23 and a33 SoCs is similar to the ones found
on sun6i-a31 SoCs but instead of a 3th phy the a23 / a33 have a hsic
interface which gets enabled by almost the same bits as used on
the a31 for the 3th phy, but not exactly the same bits so we need
a new compatible for this.

Minor spelling note: it's "3rd" not "3th".

I have almost the exact same patches in my old sun8i-otg branch.
I was planning to rebase them onto the new musb patches today,
but since you beat me to them,

Reviewed-by: Chen-Yu Tsai <wens-jdAy2FN1RRM@public.gmane.org>

My old patches are in https://github.com/wens/linux/tree/sun8i-usb
I planned on testing EHCI/OHCI first before posting anything.

Minor nitpicks:

"hsic_12m" should be "hsic_12M". And maybe add the "usb_" prefix
to the hsic clocks as well?

Otherwise,
