[PATCH 0/6] spear: Fix SPEAr3XX plgpio support

[Herve Codina <herve.codina@xxxxxxxxxxx>]

Hi,

This patch series fixes the plgpio support on SPEAr3xx SOCs.

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.

Best regards,
Herve
