serial: mvebu-uart: initial support for Armada-3700 serial port
Armada-3700's uart is a simple serial port, which doesn't support. Configuring the modem control lines. The uart port has a 32 bytes Tx FIFO and a 64 bytes Rx FIFO The uart driver implements the uart core operations. It also support the system (early) console based on Armada-3700's serial port. Known Issue: The uart driver currently doesn't support clock programming, which means the baud-rate stays with the default value configured by the bootloader at boot time [gregory.clement@free-electrons.com: Rewrite many part which are too long to enumerate] Signed-off-by: Wilson Ding <dingwei@marvell.com> Signed-off-by: Nadav Haklai <nadavh@marvell.com> Signed-off-by: Gregory CLEMENT <gregory.clement@free-electrons.com> Acked-by: Rob Herring <robh@kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
