serial: sprd: correct the wrong sequence of arguments

2019-09-21T05:18:15Z

commit 9c801e313195addaf11c16e155f50789d6ebfd19 upstream. The sequence of arguments which was passed to handle_lsr_errors() didn't match the parameters defined in that function, &lsr was passed to flag and &flag was passed to lsr, this patch fixed that.

serial: sprd: Modify the baud rate calculation formula

2019-02-26T11:35:02Z

When the source clock is not divisible by the expected baud rate and the remainder is not less than half of the expected baud rate, the old formular will round up the frequency division coefficient. This will make the actual baud rate less than the expected value and can not meet the external transmission requirements. Thus this patch modifies the baud rate calculation formula to support the serial controller output the maximum baud rate.
