| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | netdev.h should not be included in driver-model enabled builds (doing so causes compiler warnings about struct eth_driver not being declared), but we do use sunxi_gmac_initialize in the driver-model case, so move it out of netdev.h .

| * | | sunxi: axp: Move axp gpio code to a separate axpi-gpio driverHans de Goede2015-05-04-0/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

Note that this commit changes the behavior of the gmac and hdmi code for sun8i and the upcoming sun9i devices. This does not matter as sun8i does not have gmac nor hdmi, and sun9i has new hardware-blocks for these so the old code will not work there. Also this is intentional as if a sun8i / sun9i variant which does use the old hwblocks shows up then the GEN_SUN6I code paths will be the right ones to use. For completeness this also adds a SUNXI_GEN_SUN4I bool for A10/A13/A20. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Ian Campbell <ijc@hellion.org.uk>
