The first four patches of this series fixes a ressources sharing issue between the plgpio driver and the pinmux driver. Indeed, these two drivers can use the same IO address range on some SPEAr3xx SOCs. To solve the issue, a regmap (syscon managed) is used in both drivers and the plgpio driver can reference the pinmux regmap to use it. The second part of this series is related to IRQs. The plgpio on SPEAr320s SOC uses an IRQ line in the reserve range (from SPEAr320 point of view). This issue is fixed enabling all the 'reserved' IRQs and adding a dtsi file for the SPEAr320s with the correct interrupt for the plgpio node.
