[ Upstream commitb03ffc76b8] For UART devices the M_GP_LENGTH is the TX word count. For other devices this is the transaction word count. For UART devices the S_GP_LENGTH is the RX word count. The IRQ_EN set/clear registers allow you to set or clear bits in the IRQ_EN register without needing a read-modify-write.
