* sunxi: power: axp818: add support for axp818 drivervishnupatekar2015-12-103-11/+162
| | | | | | | | | | | | | | | AXP818 is rsb based PMIC and used on Allwinner A83T H8 Homlet dev board. It's registers are different and calculating reg config is different than that of earlier axp power ICs. DCDC1, DCDC2, DCDC3 and DCDC5 is implemented at the moment. all other voltages can be added subsequently. AXP datasheet is uploaded to wiki: http://linux-sunxi.org/File:AXP818_datasheet_Revision1.0.pdf Signed-off-by: Vishnu Patekar <vishnupatekar0510@gmail.com> Reviewed-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Hans de Goede <hdegoede@redhat.com>

* dm: regulator: add function device_get_supply_regulator()Przemyslaw Marczak2015-11-021-0/+7
| | | | | | | | | | | | Some devices are supplied by configurable regulator's output. But there was no function for getting it.

| | | | | | | | | | | | | | | | | | | 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>
