[PATCH v4 4/8] clk: loongson2: Allow zero divisors for dividers
Posted by Yao Zi 1 week, 5 days ago
LS2K0300 and LS2K0500 ship divider clocks which allows zero divisors,
in which case the divider acts the same as one is specified.

Let's pass CLK_DIVIDER_ALLOW_ZERO when registering divider clocks to
prepare for future introduction of these clocks.
