ARM: PL011: Separate hardware FIFO size from TTY FIFO size
With DMA support, we need to tell the TTY subsystem that the DMA buffer
is the size of the FIFO, otherwise things like tty_wait_until_sent()
will time out too early. Keep (and use) the hardware value separately
from the port->fifosize.
This was part of a larger patch from Linus Walleij, with a little
modification.
