serial: bcm283x_mu: Detect disabled serial device

2016-09-06T17:18:19+00:00

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.

net/ethoc: support private memory configurations

2016-08-15T18:34:48+00:00

The ethoc device can be configured to have a private memory region
instead of having access to the main memory. In that case egress packets
must be copied into that memory for transmission and pointers to that
memory need to be passed to net_process_received_packet or returned from
the recv callback.

net/ethoc: add CONFIG_DM_ETH support

2016-08-15T18:34:47+00:00

Extract reusable parts from ethoc_init, ethoc_set_mac_address,
ethoc_send and ethoc_receive, move the rest under #ifdef CONFIG_DM_ETH.
Add U_BOOT_DRIVER, eth_ops structure and implement required methods.

dm: imx: serial: Support DTE mode when using driver model

2016-07-19T17:52:13+00:00

The MXC UART IP can be run in DTE or DCE mode. This depends on the
board wiring and the pinmux used and hence is board specific. This
extends platform data with a new field to choose wheather DTE
mode shall be used.

serial: add BCM283x mini UART driver

2016-03-27T13:12:52+00:00

The RPi3 typically uses the regular UART for high-speed communication with
the Bluetooth device, leaving us the mini UART to use for the serial
console. Add support for this UART so we can use it.

serial: pl01x: Add support for devices with the rate pre-configured.

2016-03-22T16:16:12+00:00

For Raspberry Pi, we had the input clock rate to the pl011 fixed in
the rpi.c file, but it may be changed by firmware due to user changes
to config.txt.  Since the firmware always sets up the uart (default
115200 output unless the user changes it), we can just skip our own
uart init to simplify the boot process and more reliably get serial
output.
