Lars-Peter Clausen 6731af573a tty: xuartps: Fix tx_emtpy() callback ... The tx_empty() callback currently checks the TXEMPTY bit in the interrupt status register to decided whether the FIFO should be reported as empty or not. The bit in this register gets set when the FIFO state transitions from non-empty to empty but is cleared again in the interrupt handler. This means it is not suitable to be used to decided whether the FIFO is currently empty or not. Instead use the TXEMPTY bit from the status register which will be set as long as the FIFO is empty.
