serial: sprd: Modify the baud rate calculation formula

2019-02-26T11:35:02+00:00

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.

tty: serial: Remove redundant license text

2017-11-08T12:08:12+00:00

Now that the SPDX tag is in all tty files, that identifies the license in a specific and legally-defined manner. So the extra GPL text wording can be removed as it is no longer needed at all. This is done on a quest to remove the 700+ different ways that files in the kernel describe the GPL license text. And there's unneeded stuff like the address (sometimes incorrect) for the FSF which is never needed. No copyright headers or other non-license-description text was removed.
