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> |
