*	sunxi: axp221: Add ELDO[1-3] support	Siarhei Siamashka	2015-01-22	-0/+7
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	And also add Kconfig option for selecting ELDO3 voltage. The reason for having this option is that the Android kernel sets ELDO3 to 1.2V when powering up LCD in the case if 'lcd_if' configuration variable is set to 6 (LCD_IF_EXT_DSI) in the FEX file. Most likely to supply power for a SSD2828 chip. However on the MSI Primo81 tablet, which is using this particular 'lcd_if = 6' setup for LCD, setting the ELDO3 voltage appears to be unnecessary and it works regardless. Having no schematics of this tablet, I can only guess that 1.2V is supplied to SSD2828 in some other way.

*	sunxi: axp221: Add support for controlling the drivebus pin	Hans de Goede	2015-01-14	-0/+9
\| \| \| \| \| \| \| \| \|	The axp221 / axp223's N_VBUSEN pin can be configured as an output rather then an input, add axp_drivebus_enable() and _disable() functions to set the pin in output mode and control it.

*	sunxi: axp221: Explicitly turn off unused voltages	Hans de Goede	2015-01-14	-1/+7
\| \| \| \| \| \| \| \| \|	Explicitly turn off unused voltages, rather then leaving them as is. Likewise explictly enabled the dcdc convertors, rather then assuming they are already enabled at boot. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Ian Campbell <ijc@hellion.org.uk>
*	sunxi: axp221: Add axp223 support	Hans de Goede	2015-01-14	-0/+4
\| \| \| \| \| \| \| \| \|	The axp223 appears to be the same as the axp221, except that it uses the rsb to communicate rather then the p2wi. At least all the registers we use are 100% the same. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Ian Campbell <ijc@hellion.org.uk>
*	sun6i: axp221: Add axp221_get_sid function	Hans de Goede	2015-01-14	-0/+6
\| \| \| \| \| \| \| \|	For sun6i the SID is stored in the pmic, rather then in the SoC itself, add a function to retreive the sid. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Ian Campbell <ijc@hellion.org.uk>
*	sunxi: axp221: Fix using the wrong register address for ALDO2	Hans de Goede	2015-01-06	-1/+1
\| \| \| \| \| \| \| \|	This fixes us never programming ALDO2, and programming the ALDO2 voltage into ALDo1. Reported-by: Siarhei Siamashka <siarhei.siamashka@gmail.com> Signed-off-by: Hans de Goede <hdegoede@redhat.com>
