[PATCH 3/8] mailbox: Add transmit done by blocking option

2018-05-08 Thread Mikko Perttunen
Add a new TXDONE option, TXDONE_BY_BLOCK. With this option, the send_data function of the mailbox driver is expected to block until the message has been sent. The new option is used with the Tegra Combined UART driver to minimize unnecessary overhead when transmitting data. Signed-off-by: Mikko
