2016-04-01pmic: Add support for Qualcomm PM8916 PMICMateusz Kulikowski
This PMIC is connected on SPMI bus so needs SPMI support enabled. Signed-off-by: Mateusz Kulikowski <mateusz.kulikowski@gmail.com> Reviewed-by: Simon Glass <sjg@chromium.org> Tested-by: Simon Glass <sjg@chromium.org>
2016-04-01sunxi: Add support for Allwinner A64 SoCsSiarhei Siamashka
The Allwinner A64 SoC is used in the Pine64. This patch adds all bits necessary to compile U-Boot for it running in AArch64 mode. Unfortunately SPL is not ready yet due to legal problems, so we need to boot using the binary boot0 for now.

This adds support for powering off (the omap SoC) from the twl6030. Signed-off-by: Paul Kocialkowski <contact@paulk.fr>
2016-03-15power: twl6030: Remove ifdef around the codePaul Kocialkowski
The TWL6030 power driver is only built when CONFIG_TWL6030_POWER is selected, thus there is no reason to wrap the code with ifdef. Signed-off-by: Paul Kocialkowski <contact@paulk.fr>
2016-03-15power: twl6030: Clear VUSB_IN_PMID bit on USB device setupPaul Kocialkowski
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>
2016-03-15power: twl6030: Configure VUSB voltage on USB device setupPaul Kocialkowski
This explicitly sets VUSB voltage to 3.3V when enabling USB. Signed-off-by: Paul Kocialkowski <contact@paulk.fr>
2016-03-15power: twl6030: Device-index-specific MMC power initializationPaul Kocialkowski
Not every device has multiple MMC slots available, so it makes sense to enable only the required LDOs for the available slots. Generic code in omap_hsmmc will enable both VMMC and VAUX1, in doubt. Signed-off-by: Paul Kocialkowski <contact@paulk.fr>
2016-03-15power: twl6030: Enable VAUX1 for eMMC power, depending on BOOT2 valuePaul Kocialkowski
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.

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.

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.
