serial: Add serial_mvebu_a3700 for Armada 3700 SoC

2016-09-27T15:29:52Z

The Armada 3700's UART is a simple serial port. It has a 32 bytes Tx FIFO and a 64 bytes Rx FIFO integrated. This patch adds support for this UART including the DEBUG UART functions for very early debug output.

serial: ns16550: Support clocks via phandle

2016-09-21T13:04:32Z

Previously ns16550 compatible UARTs probed via device tree have needed their device tree nodes to contain a clock-frequency property. An alternative to this commonly used with Linux is to reference a clock via a phandle. This patch allows U-Boot to support that, retrieving the clock frequency by probing the appropriate clock device. For example, a system might choose to provide the UART base clock as a reference to a clock common to multiple devices: sys_clk: clock { compatible = "fixed-clock"; #clock-cells = <0>; clock-frequency = <10000000>; }; uart0: uart@10000000 { compatible = "ns16550a"; reg = <0x10000000 0x1000>; clocks = <&sys_clk>; }; uart1: uart@10000000 { compatible = "ns16550a"; reg = <0x10001000 0x1000>; clocks = <&sys_clk>; }; This removes the need for the frequency information to be duplicated in multiple nodes and allows the device tree to be more descriptive of the system.

serial: bcm283x_mu: Detect disabled serial device

2016-09-06T17:18:19Z

On the raspberry pi, you can disable the serial port to gain dynamic frequency scaling which can get handy at times. However, in such a configuration the serial controller gets its rx queue filled up with zero bytes which then happily get transmitted on to whoever calls getc() today. This patch adds detection logic for that case by checking whether the RX pin is mapped to GPIO15 and disables the mini uart if it is not mapped properly. That way we can leave the driver enabled in the tree and can determine during runtime whether serial is usable or not, having a single binary that allows for uart and non-uart operation.

ARM: uniphier: change UNIPHIER_SERIAL to default y option

This is very likely to be necessary for normal use cases. Set its default to 'y' for shorter defconfig files. Signed-off-by: Masahiro Yamada
