[PATCH v2 10/20] clk: sunxi: Add support for table-based divider clocks

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



A few of the clock modules have odd dividers, such as
the 2 lowest dividers being the same (2), or have the
same divider when the highest bit is set.

This patch adds support for optional divider tables,
so the clock framework will know about the odd values.
