[Masahiro Yamada]

Simon,


Any comment on this patch?

> These two properties are necessary for SPL to get clocks from DT.

> Note:
> For now, only clock look-up by index is supported (clk_get_by_index()
> function), so "clock-names" is never parsed in U-Boot.  However, we
> may want to support something like clk_get_by_name() in the future,
> so let's keep "clock-names" as well as "clocks".
