[PATCH v2] ARM: dts: artpec: update clock bindings in artpec6.dtsi

[PATCH v2] ARM: dts: artpec: update clock bindings in artpec6.dtsi

[Lars Persson]

The clock binding for the main clock controller was changed to an
indexed controller style binding on request of the clk
maintainers. This updates the dtsi to use the new bindings.

v2: Use numerical clock indexes to enable merge before the clock driver bindings
are in the tree.

I found this patch while going through stuff that had not been applied yet.
Is this still the latest version that we should apply for v4.7?

Yes it the latest. The clock driver will hit the tree in 4.7-rc1, not until then can we use the binding header file.

Thanks.

Applied to next/dt for v4.7, thanks!
