2016-02-23sunxi: power: add support for sy8106a driverJelle van der Waa
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.

2016-01-26sunxi: power: axp818: Enable support for ALDOsChen-Yu Tsai
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.

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.

2016-01-21dm: power: Allow regulators to not implement all operationsSimon Glass
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. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-01-21dm: power: Tidy up debugging output and return valuesSimon Glass
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. Signed-off-by: Simon Glass <sjg@chromium.org>

We have flipped CONFIG_SPL_DISABLE_OF_CONTROL.

It refers to CONFIG_OF_CONTROL for U-boot proper and CONFIG_SPL_OF_CONTROL for SPL. Also, we no longer have to cancel CONFIG_OF_CONTROL in include/config_uncmd_spl.h and scripts/Makefile.spl.
