[PATCH 1/2] clk: divider: prepare for minimum divider
Afzal Mohammed
afzal at ti.com
Tue Jan 22 11:39:00 EST 2013
Some of clocks can have a limit on minimum divider value that can be
programmed, prepare for such a support.
Add a new field min_div for the basic divider clock. Enhance runtime
registration and static definition helper of basic clock divider so
that minimum divider value can be specified and modify all call sites.
