[ Upstream commit ed84ef1cd7 ]
Two fixes in one:
- In the "impose hardware constraints" block, the "logical" divider
value (aka. not translated to the hardware) was clamped to fit in the
register area, but this totally ignored the fact that the divider
value can itself have a fixed divider.
- The code that made sure that the divider value returned by the
function was a multiple of its own fixed divider could result in a
wrong value being calculated, because it was rounded down instead of
rounded up.
Fixes: 4afe2d1a6e ("clk: ingenic: Allow divider value to be divided")
