[PATCH v2 0/2] ARM: berlin: add GPIO support for the BG2Q

[Antoine Ténart]

This series add the support for the GPIOs of the Berlin BG2Q. We use the
newly integrated dwapb GPIO driver here.

This applies on top of Alexandre's BG2Q symbol introduction[1] and the dwapb
gpio patch fixing IRQ initialization[2].

[1] https://patchwork.kernel.org/patch/3876141/
[2] https://lkml.org/lkml/2014/4/7/96

Changes since v1:
	- s/gpio-controller@/gpio-port@/ in device tree
	- moved ARCH_REQUIRE_GPIOLIB to ARCH_BERLIN in Kconfig

[PATCH v2 1/2] ARM: berlin: add the LIBGPIO as a dependency for the BG2Q

[Antoine Ténart]

The BG2Q has GPIOs driven by the dwapb GPIO driver. Add the LIBGPIO as a
dependency to be able to support them.

[PATCH v2 2/2] ARM: dts: berlin: add GPIO nodes for the BG2Q

[Antoine Ténart]

The Marvell Berlin BG2Q has 6 GPIO ports compatible with the snps,dw-apb-gpio
driver. This patch add the corresponding device tree nodes.

Patch 1 applied to berlin/soc,
Patch 2 applied to berlin/dt,

both with Jisheng's Reviewed-by.

Thanks!
