* sunxi: axp2xx: disable ldoio0/1 at bootHans de Goede2016-09-17-0/+28
| | | | | | | | | | When cold-booting the ldoio0/1 regulators are always off / the gpios are always at tristate. But when re-booting from android these are sometimes on. Disable them at axp_init time (iow as early as possible) to remove this difference between a cold boot and a reboot.

* power: twl6030: Clear VUSB_IN_PMID bit on USB device setupPaul Kocialkowski2016-03-15-0/+1
| | | | | | | | | | | | 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). Signed-off-by: Paul Kocialkowski <contact@paulk.fr>

| | | | | | | | | | | | | | | | 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.
