From 30530791a7a032dc27dbbab56b8afabd5138074c Mon Sep 17 00:00:00 2001 From: Wilson Ding Date: Tue, 16 Feb 2016 19:14:53 +0100 Subject: 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 Signed-off-by: Nadav Haklai Signed-off-by: Gregory CLEMENT Acked-by: Rob Herring Signed-off-by: Greg Kroah-Hartman --- include/uapi/linux/serial_core.h | 3 +++ 1 file changed, 3 insertions(+) (limited to 'include/uapi/linux/serial_core.h') diff --git a/include/uapi/linux/serial_core.h b/include/uapi/linux/serial_core.h index 3e5d757407fb..e513a4ee369b 100644 --- a/include/uapi/linux/serial_core.h +++ b/include/uapi/linux/serial_core.h @@ -261,4 +261,7 @@ /* STM32 USART */ #define PORT_STM32 113 +/* MVEBU UART */ +#define PORT_MVEBU 114 + #endif /* _UAPILINUX_SERIAL_CORE_H */ -- cgit v1.2.3-59-g8ed1b
