2016-03-31sunxi: axp: Generalize register macros for VBUS drive GPIOChen-Yu Tsai
VBUS drive is supported on AXP221 and later PMICs. Rework the macros so we can support this on later PMICs without too much work. Signed-off-by: Chen-Yu Tsai <wens@csie.org> Reviewed-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Hans de Goede <hdegoede@redhat.com>
2015-10-20sunxi: power: Unify axp pmic function namesHans de Goede
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>
2015-05-04sunxi: axp: Remove non driver-model support from the axp gpio codeHans de Goede
Now that all sunxi boards are using driver-model for gpio (*), we can remove the non driver-model support from the axp gpio code, and the glue to call into the axp gpio code from the sunxi_gpio non driver-model code. *) For the regular u-boot build, SPL still uses non driver-model gpio for now, but the SPL never uses axp gpios support and we were already not building axp-gpio support for the SPL.

2015-05-04sunxi: axp: Add driver-model support to the axp_gpio codeHans de Goede
Add driver-model support to the axp_gpio code, note that this needs a small tweak to the driver-model version of sunxi_name_to_gpio to deal with the vbus detect and enable pins which are not standard numbered gpios.

2015-05-04sunxi: axp: Move axp gpio code to a separate axpi-gpio driverHans de Goede
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.
