Rajendra Nayak 2c043bcbf2 regulator: pass additional of_node to regulator_register()
With device tree support for regulators, its needed that the
regulator_dev->dev device has the right of_node attached.
To be able to do this add an additional parameter to the
regulator_register() api, wherein the dt-adapted driver can
then pass this additional info onto the regulator core.

Wolfram Sang 59bfee6e06 i2c: Remove obsolete cleanup for clientdata
A few new i2c-drivers came into the kernel which clear the clientdata-pointer
on exit. This is obsolete meanwhile, so fix it and hope the word will spread.

Axel Lin 58d463eec8 regulator: ad5398 - fix a memory leak
In current implementation, the address return from regulator_register()
is different from the address for regulator_unregister().

Sonic Zhang 839b8362a7 regulator: make sure the regulator is available prior to the consumers.
Some systems are likely to want this to be subsys_initcall() to
make sure the regulator is available prior to the consumers.

Sonic Zhang 8b385d9b97 regulator: new drivers for AD5398 and AD5821
The AD5398 and AD5821 are single 10-bit DAC with 120 mA output current
sink capability. They feature an internal reference and operates from
a single 2.7 V to 5.5 V supply.

This driver supports both the AD5398 and the AD5821.  It adapts into the
voltage and current framework.
