pmic: tps65218: add useful functions and defines

2016-02-24T23:44:07+00:00

Add the following functions:
tps65218_reg_read() for accessing redisters
tps65218_toggle_fseal() for toggling the fseal bit
tps65218_lock_fsea() for locking the fseal bit to 1

Add the following defines:
All status register bits

sunxi: power: add support for sy8106a driver

2016-02-23T19:50:07+00:00

SY8106A is a PMIC which is used on the Allwinner
H3 Orange Pi Pc and Plus board. The VOUT1_SEL register is
implemented to set the default V-CPU voltage to 1200 mV.

This driver is required to ensure the SY8106A V-CPU
voltage is set to 1200 mV after a software reset. On cold
boot the default SY8106A output voltage is selected to be
1200 mV by a pair of resistors on the Orange Pi PC and Plus.

sunxi: power: axp818: Enable support for ALDOs

2016-01-26T15:20:05+00:00

Previously, AXP818 ALDO support was partially added to Kconfig, but
never enabled in the board file, nor properly set or configured in
Kconfig. The boards continue to work because the AXP818 is designed
to pair with the A83T/H8, and the default voltages match the reference
design's requirements.

power: axp818: Add support for DLDO and ELDO regulators

2016-01-26T15:20:05+00:00

AXP818 provides an array of LDOs to provide power to various peripherals.
None of these regulators are critical.

power: axp: merge separate DLDO functions into 1

2016-01-26T15:20:05+00:00

Instead of one function for each DLDO regulator, make 1 function that
takes an extra "index". Since the control bits for the DLDO regulators
are contiguous, this makes the function very simple. This removes a lot
of duplicate code.

dm: power: Allow regulators to not implement all operations

2016-01-22T03:42:35+00:00

Some regulators will not implement any operations (e.g. fixed regulators).
This is not an error, so allow the autoset process to continue when one
of these regulators is found.

dm: power: Tidy up debugging output and return values

2016-01-22T03:42:35+00:00

The currect PMIC debugging is a little confusing. Adjust it so that it is
clear whether the operation succeeded or failed. Also, avoid creating a new
error return value when a perfectly good one is already available.
