Hi, This series add support for (async) FIFO on the transmit path of the PL011 UART.
Last patch still broken (chars are emitted async), still patches 1-11 could be merged for this release... Since v4: - Rebased (loopback) - Addressed Richard & Juan migration comments - Split in smaller patches Since v3: - Document migration bits (Alex, Richard) - Just check FIFO is not empty in pl011_xmit_fifo_state_needed (rth) - In pl011_xmit check TX enabled first, and ignore < 8-bit TX (rth) Since v2: - Added R-b tags - Addressed Richard comments on migration Since v1: - Restrict pl011_ops[] impl access_size, - Do not check transmitter is enabled (Peter), - Addressed Alex's review comments, - Simplified migration trying to care about backward compat, but still unsure...
