Detailed Description

struct msm_serial_hs_platform_data : Rx activity irq : extra character to be inserted to Rx tty on wakeup : 1 = insert rx_to_inject. 0 = do not insert extra character : function called before every Tx transaction

This is an optional structure required for UART Rx GPIO IRQ based wakeup from low power state. UART wakeup can be triggered by RX activity (using a wakeup GPIO on the UART RX pin). This should only be used if there is not a wakeup GPIO on the UART CTS, and the first RX byte is known (eg., with the Bluetooth Texas Instruments HCILL protocol), since the first RX byte will always be lost. RTS will be asserted even while the UART is clocked off in this mode of operation.
