Enable driver model for I2C. The I2C uclass interface: probe, read,
write and speed, is implemented with the bus drivers operations,
which provide methods for bus setting and data transfer. Each chip
device (bus child) info is kept as parent platdata. The interface
is defined in include/i2c.h. When i2c bus driver supports the i2c
uclass, but the device drivers not, then DM_I2C_COMPAT config can
be used as compatibility layer.

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. Signed-off-by: Simon Glass <sjg@chromium.org>

config I2C_CROS_EC_TUNNEL
tristate "Chrome OS EC tunnel I2C bus"
depends on CROS_EC
help
This provides an I2C bus that will tunnel i2c commands through to
the other side of the Chrome OS EC to the I2C bus connected there.
This will work whatever the interface used to talk to the EC (SPI,
I2C or LPC). Some Chromebooks use this when the hardware design
does not allow direct access to the main PMIC from the AP.
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. Signed-off-by: Simon Glass <sjg@chromium.org>

config I2C_CROS_EC_LDO
bool "Provide access to LDOs on the Chrome OS EC"
depends on CROS_EC
---help---
On many Chromebooks the main PMIC is inaccessible to the AP. This is
often dealt with by using an I2C pass-through interface provided by
the EC. On some unfortunate models (e.g. Spring) the pass-through
is not available, and an LDO message is available instead. This
option enables a driver which provides very basic access to those
regulators, via the EC. We implement this as an I2C bus which
emulates just the TPS65090 messages we know about. This is done to
avoid duplicating the logic in the TPS65090 regulator driver for
enabling/disabling an LDO.

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.
