* sunxi: power: Add support for disabling axp209 regulatorsHans de Goede2015-10-201-4/+46
| | | | | | | Add support for disabling the regulators found on the axp209 pmic. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Ian Campbell <ijc@hellion.org.uk>
* sunxi: power: Use pmic_bus functions for axp152 / axp209 driverHans de Goede2015-10-201-21/+15
| | | | | | | | | Use the generic pmic_bus helpers for the axp152 / axp209 drivers, rather then having them define their own register read / write functions. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Ian Campbell <ijc@hellion.org.uk>
* sunxi: power: Unify axp pmic function namesHans de Goede2015-10-201-31/+8
| | | | | | | | | Stop prefixing the axp functions for setting voltages, etc. with the model number, there ever is only one pmic driver built into u-boot, this allows simplifying the callers. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Ian Campbell <ijc@hellion.org.uk>
* sunxi: axp: Move axp gpio code to a separate axpi-gpio driverHans de Goede2015-05-041-64/+0
| | | | | | | | | | | | | | | | | | | | Move the axp-gpio code out of the drivers/power/axp*.c code, and into a new separate axpi-gpio driver. This change drops supports for the gpio3 pin on the axp209, as that requires special handling, and no boards are using it. Besides cleaning things up by moving the code to a separate driver, as a bonus this change also adds support for the (non vusb) gpio pins on the axp221 and the gpio pins on the axp152. The new axp-gpio driver gets its own Kconfig option, and is only enabled on boards which need it. Besides that it only gets enabled in the regular u-boot build and not for the SPL as we never need it in the SPL.

* sunxi: axp: Change axp_gpio_foo prototypes to match gpio uclass opsHans de Goede2015-05-041-5/+5
| | | | | | | | | | | | | Change the axp_gpio_foo function prototypes to match the gpio uclass op prototypes, this is a preparation patch for moving the axp gpio code to a separate driver-model gpio driver. Note that the ugly calls with a NULL udev pointer in drivers/gpio/sunxi_gpio.c this adds are removed in a later patch.

* sunxi: axp209: fix incorrect limits on ldo3Iain Paton2015-03-261-1/+1
| | | | | | | | | | | | | | | | | | board/sunxi/board.c tries to set ldo3 to 2.8v however drivers/power/axp209.c contains an incorrect limit on ldo3 of 2.275v The origin of the incorrect limit seems likely due to some inconsistencies in the axp209 datasheet. ldo3 is described with different limits in different sections. register 0x29 uses 7 bits for voltage configuration while the 2.275v limit would apply if only 6 bits were used. Probably this is a cut&paste error from register 0x23 The linux kernel driver has the correct limit and operation up to the 2.8v required by my board has been physically verified with a multimeter.

* sunxi: axp209: Disable interrupts when intializing the axp209Hans de Goede2015-01-221-1/+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: gpio: Add support for gpio pins on the AXP209 pmicHans de Goede2015-01-141-0/+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>
