2017-06-01dm: Rename dev_addr..() functionsSimon Glass
These support the flat device tree. We want to use the dev_read_..() prefix for functions that support both flat tree and live tree. So rename the existing functions to avoid confusion. In the end we will have: 1. dev_read_addr...() - works on devices, supports flat/live tree 2. devfdt_get_addr...() - current functions, flat tree only 3. of_get_address() etc. - new functions, live tree only All drivers will be written to use 1. That function will in turn call either 2 or 3 depending on whether the flat or live tree is in use. Note this involves changing some dead code - the imx_lpi2c.c file.

2015-08-05cros_ec: Support the LDO access method used by springSimon Glass
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>
2015-08-05dm: cros_ec: Convert the I2C tunnel code to use driver modelSimon Glass
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>
2015-08-05dm: i2c: Add support for multiplexed I2C busesSimon Glass
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. Signed-off-by: Simon Glass <sjg@chromium.org>
