ARM: sunxi: Add pinctrl driver for Allwinner SoCs The Allwinner SoCs have an IP module that handle both the muxing and the GPIOs. This IP has 8 banks of 32 bits, with a number of pins actually useful for each of these banks varying from one to another, and depending on the SoC used on the board. This driver only implements the pinctrl part, the gpio part will come eventually.

ARM: sunxi: gpio: Add Allwinner SoCs GPIO drivers The IP responsible for the muxing on the Allwinner SoCs are also handling the GPIOs on the system. This patch adds the needed driver that relies on the pinctrl driver for most of its operations. The number of pins available for GPIOs operations are already declared in the pinctrl driver, we only need to probe a generic driver to handle the banks available for each SoC. This driver has been tested on a A13-Olinuxino. Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

This patch adds the needed driver that relies on the pinctrl driver for most of its operations. The number of pins available for GPIOs operations are already declared in the pinctrl driver, we only need to probe a generic driver to handle the banks available for each SoC. This driver has been tested on a A13-Olinuxino. Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

ARM: sunxi: Add pinctrl driver for Allwinner SoCs The Allwinner SoCs have an IP module that handle both the muxing and the GPIOs. This IP has 8 banks of 32 bits, with a number of pins actually useful for each of these banks varying from one to another, and depending on the SoC used on the board. This driver only implements the pinctrl part, the gpio part will come eventually.
