* cros_ec: Honor the google,remote-bus dt propertyMoritz Fischer2016-10-08-1/+23
| | | | | | | | | | | | Boards where ECs that use a I2C port != 0 specify this in the devicetree file via the google,remote-bus property. Previously this was ignored and hardcoded to port 0.

* i2c: Drop redundant platform data setting in driversSimon Glass2016-08-12-1/+0
| | | | | | | | | The i2c uclass has a default setting for per_child_platdata_auto_alloc_size so drivers do not need to set it. Remove this from drivers to avoid confusion. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
* dm: cros_ec: Convert the I2C tunnel code to use driver modelSimon Glass2015-08-05-0/+41
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>
