* sunxi: axp221: Add ELDO[1-3] supportSiarhei Siamashka2015-01-22-0/+43
| | | | | | | | | | | | | | | | | | 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: axp209: Disable interrupts when intializing the axp209Hans de Goede2015-01-22-1/+13
| | | | | | | | | | We do not use the axp209 interrupt, and at least in my mini-x (which does not have a power button) the pwr-button pin and the irq pin are soldered together, so if the axp209 keeps it irq asserted too long it will see a 10s pwr-button press and hard power off the board, disabling the irqs fixes this.

* | sunxi: axp221: Protect axp221_init against multiple callsHans de Goede2015-01-14-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The voltage setting code knows it needs to call axp221_init before calling the various voltage setting functions. But users of axp utility functions like axp221_get_sid() do not know this, so the utility functions always call axp221_init() to ensure that the p2wi / rsb setup magic has been done. Since doing this repeatedly is quite expensive, add a check to axp221_init so that it only does the initialization once.

* | sunxi: gpio: Add support for gpio pins on the AXP209 pmicHans de Goede2015-01-14-0/+72
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some boards use GPIO-s on the pmic, one example of this is the A13-OLinuXino board, which uses gpio0 of the axp209 for the lcd-power signal. This commit adds support for gpio pins on the AXP209 pmic, the sunxi_gpio.c changes are universal, adding gpio support for the other AXP pmics (when necessary) should be a matter of adding the necessary axp_gpio_foo functions to their resp. drivers, and add "#define AXP_GPIO" to their header file. Note this commit only adds support for the non device-model version of the gpio code, patches for adding support to the device-model version are very welcome. The string representation for these gpio-s is AXP0-#, the 0 in the AXP0 prefix is there in case we need to support gpio-s on more then 1 pmic in the future. At least A80 boards have 2 pmics, and we may end up needing to support gpio-s on both. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Ian Campbell <ijc@hellion.org.uk>

* | sunxi: axp221: Make dcdc1 voltage configurableHans de Goede2015-01-14-0/+10
| | | | | | | | | | | | | | | | | | | | The dcdc1 voltage is typically used as generic 3.3V IO voltage for things like GPIO-s, sdcard interfaces, etc. On most boards this is undervolted to 3.0V to safe battery, but not on all, make it configurable so that we can use the same settings as the original firmware on all boards.
