ad827a500b i2c: xiic: Add Xilinx AXI I2C driver
Add Xilinx AXI I2C controller driver based on the Linux i2c-xiic driver.
This driver is stripped of all the IRQ handling and uses pure polling,
yet tries to retain most of the structure of the Linux driver to make
backporting of fixes easy.

Note that the IP has a known limitation on 255 bytes read and write,
according to xilinx this is still being worked on [1].

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

This arch does not seem to be supported / used at all in the current

Please note that this patch also removes these config options:

- CONFIG_PL011_SERIAL_RLCR
- CONFIG_PL011_SERIAL_FLUSH_ON_INIT

As they only seem to be referenced by u8500 based boards. Without any
such board in the current code, these config option don't make sense
any more. Lets remove them as well.

If someone still wants to use this platform, then please send patches
to re-enable support by adding at least one board that references this
code.

f48eaf01b2 cros_ec: Support the LDO access method used by spring
Add a driver to support the special LDO access used by spring. This is a
custom method in the cros_ec protocol - it does not use an I2C
pass-through.

There are two implementation choices:

1. Write a special LDO driver which can talk across the EC. Duplicate all
the logic from TPS65090 for retrying when the LDO fails to come up.

2. Write a special I2C bus driver which pretends to be a TPS65090 and
transfers reads and writes using the LDO message.

Either is distasteful. The latter method is chosen since it results in less
code duplication and a fairly simple (30-line) implementation of the core
logic.

The crosec 'ldo' subcommand could be removed (since i2c md/mw will work
instead) but is retained as a convenience.

cc456bd7df dm: cros_ec: Convert the I2C tunnel code to use driver model
The Chrome OS EC supports tunnelling through to an I2C bus on the EC. This
currently uses a copy of the I2C command code and a special 'crosec'
sub-command.

With driver model we can define an I2C bus which tunnels through to the EC,
and use the normal 'i2c' command to access it. This simplifies the code and
removes some duplication.

Add an I2C driver which tunnels through to the EC. Adjust the EC code to
support binding child devices so that it can be set up. Adjust the existing
I2C xfer function to fit driver model better.

For now the old code remains to allow things to still work. It will be
removed in a later patch once the new flow is fully enabled.

3d1957f0ea dm: i2c: Add support for multiplexed I2C buses
Add a new I2C_MUX uclass. Devices in this class can multiplex between
several I2C buses, selecting them one at a time for use by the system.
The multiplexing mechanism is left to the driver to decide - it may be
controlled by GPIOs, for example.

The uclass supports only two methods: select() and deselect().

The current mux state is expected to be stored in the mux itself since
it is the only thing that knows how to make things work. The mux can
record the current state and then avoid switching unless it is necessary.
So select() can be skipped if the mux is already in the correct state.
Also deselect() can be made a nop if required.

This commit adds driver model support to software emulated i2c bus driver.
This driver supports kernel-style device tree bindings. Fdt properties in use:
- compatible - "i2c-gpio"
- gpios      - data and clock GPIO pin phandles
- delay-us   - micro seconds delay between GPIOs toggle operations,
               which is 1/4 of I2C speed clock period.

Added:
- Config: CONFIG_DM_I2C_GPIO
- File: drivers/i2c/i2c-gpio.c
- File: doc/device-tree-bindings/i2c/i2c-gpio.txt

Driver base code is taken from: drivers/i2c/soft-i2c.c, changes:
- use "i2c-gpio" naming
- update comments style
- move preprocesor macros into functions
- add device tree support
- add driver model i2c support

1fa96e80ec i2c: mxs: Add basic support for i2c framework
This patch just converts the function prototypes used throughout
this driver to match those of the i2c framework. There is so far
no functional change. This patch does not do the deeper integration
of the framework bits.

0db2bbdc04 mvtwsi: convert to CONFIG_SYS_I2C framework
Note this has only been tested on Allwinner sunxi devices (support for which
gets introduced by a later patch).

The kirkwood changes have been compile tested using the wireless_space board
config, the orion5x changes have been compile tested using the edminiv2 board
config.

b46226bdb5 i2c: IHS I2C master driver
IHS I2C master support was merely a hack in the osd driver.
Now it is a proper u-boot I2C framework driver, supporting the
v2.00 master features.
