dm: core: Replace of_offset with accessor

2017-02-08T13:12:14+00:00

At present devices use a simple integer offset to record the device tree
node associated with the device. In preparation for supporting a live
device tree, which uses a node pointer instead, refactor existing code to
access this field through an inline function.

serial, ns16550: bugfix: ns16550 fifo not enabled

2017-01-20T14:15:19+00:00

commit: 65f83802b7a5b "serial: 16550: Add getfcr accessor"
breaks u-boot commandline working with long commands
sending to the board.

Since the above patch, you have to setup the fcr register.

For board/archs which enable OF_PLATDATA, the new field
fcr in struct ns16550_platdata is not filled with a
default value ...

This leads in not setting up the uarts fifo, which ends
in problems, when you send long commands to u-boots
commandline.

Detected this issue with automated tbot tests on am335x
based shc board.

The error does not popup, if you type commands. You need
to copy&paste a long command to u-boots commandshell
(or send a long command with tbot)

Possible boards/plattforms with problems:
./arch/arm/cpu/arm926ejs/lpc32xx/devices.c
./arch/arm/mach-tegra/board.c
./board/overo/overo.c
./board/quipos/cairo/cairo.c

Kconfig: CONFIG_OF_PLATDATA doesn't really exist

2017-01-14T17:20:23+00:00

There is no CONFIG_OF_PLATDATA, only CONFIG_SPL_OF_PLATDATA, so rename
the two references to CONFIG_OF_PLATDATA to CONFIG_SPL_OF_PLATDATA.

serial: 16550: Add Ingenic JZ4780 support

2016-12-19T17:26:37+00:00

Add compatibility string for the Ingenic JZ4780 SoC, the necessary
UART enable bit into FCR and register shift. Neither are encoded
in the DTS coming from Linux, so we need to support it this way.

serial: 16550: Add port type as driver data

2016-12-19T17:26:37+00:00

Add driver data to each compatible string to identify the type of
the port. Since all the ports in the driver are entirely compatible
with 16550 for now, all are marked with PORT_NS16550. But, there
are ports which have specific quirks, like the JZ4780 UART, which
do not have any DT property to denote the quirks. Instead, Linux
uses the compatible string to discern such ports and enable the
necessary quirks.

serial: 16550: Add getfcr accessor

2016-12-19T17:26:36+00:00

Add function which allows fetching the default FCR register setting
from platform data for DM , while retaining old behavior for non-DM
by returning UART_FCRVAL.

arm: imx: add i.MX53 Beckhoff CX9020 Embedded PC

2016-12-16T11:57:12+00:00

Add CX9020 board based on mx53loco.
Add simplified imx53 base device tree from kernel v4.8-rc8, to reuse
serial_mxc with DTE and prepare for device tree migration of other
functions and imx53 devices.

The CX9020 differs from i.MX53 Quick Start Board by:
- use uart2 instead of uart1
- DVI-D connector instead of VGA
- no audio
- CCAT FPGA connected to emi
- enable rtc

serial: bcm283x_mu: support disabling after initialization

2016-11-29T01:09:50+00:00

For the Raspberry Pi 3 it needs to be possible to disable the serial
device after initialization happens, as only after the GPIO device is available
it is known whether the mini uart is usable.

2016-11-29T01:09:47+00:00

To be able to represent the skip-init platdata element with OF_CONTROL,
it needs to be read from the device tree as well and put into the platform data.
