When enabling a fixed regulator, it may take some time to rise to the
correct voltage. If we do not delay here then subsequent operations
will fail.

In Tegra186, SoC power domains are manipulated using IPC requests to
the BPMP (Boot and Power Management Processor). This change implements a
driver that does that.

Many SoCs allow power to be applied to or removed from portions of the SoC
(power domains). This may be used to save power. This API provides the
means to control such power management hardware.

Quite a few places have a bind() method which just calls dm_scan_fdt_dev().
We may as well call dm_scan_fdt_dev() directly. Update the code to do this.

When booting from USB, the bootrom sets the VUSB_IN_PMID bit of the MISC2
register of the TWL6030. However, U-Boot sets the VUSB_IN_VSYS bit to enable
VBUS input. As both bits are contradictory, enabling both disables the input,
according to the TWL6030 TRM.
Thus, we need to clear the VUSB_IN_PMID bit in case of an USB boot (which could
just as well be a memory boot after USB timed out).

This enables the VAUX1 supply, used for eMMC power in standard configurations.
Its voltage is determined by the value of the BOOT2 pin of the TWL6030.
Note that the TWL6030 might already have enabled this regulator at startup
(depending on the value of the BOOT3 pin of the TWL6030), according to the
TWL6030 datasheet.

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.

never enabled in the board file, nor properly set or configured in
Kconfig. The boards continue to work because the AXP818 is designed
