ARM: mvebu: Add pinctrl support to Armada XP SoCs This commits adds the necessary device tree information to define the compatible property for the pinctrl driver instance of Armada XP SoCs. Until now, the device tree representation considered the Armada XP as a single SoC. But in fact, there are three different SoCs in the Armada XP families, with different number of CPU cores, different number of Ethernet interfaces... and different number of muxable pins or functions. We therefore introduce three armada-xp-mv78xx0.dtsi for the three SoCs of the Armada XP family. The current armada-xp-db.dts evaluation board uses the MV78460 variant of the SoC.

arm: mvebu: add DT information for GPIO banks on Armada 370 and XP The gpioX aliases are needed so that the driver can use of_alias_get_id() to get a 0-based number of the GPIO bank, which we then use to compute the base GPIO of the bank being probed. This is similar to what gpio-mxs.c is doing.
