> Fix the issue of max_timeout being calculated larger than actual value.
> The calculation result of freq / (S3C2410_WTCON_PRESCALE_MAX + 1) /
> S3C2410_WTCON_MAXDIV is smaller than the actual value because the
> remainder is discarded during the calculation process. This leads to a larger

> To resolve this issue, the order of calculations in the computation process has
