The series is mainly about the support of 8250 UART without TEMT interrupt. I saw that there was some development in the past but it was never merged. Since the last discussion were quite some time ago, I was not sure if I should post a v4 over the last v3 or start from scratch so I decided to post a new patch. Please advice if I should have done the reverse. The approach is a little different from the last proposed patch which was doing using a polling at 100us. I tought that it could be really long on some fast baudrate and really not that long on slow baudrate. The current approach is to calculate the time of a bytes when the settings are changed. When we get the interrupt for the empty FIFO, it's the longer it can take to empty the shift register. The other two patches are to use that features with the PORT_16550A_FSL64 found on some chip like the LS1043A.
