Subject: [PATCH 0/2] Add support for programming gs101 EINT_WAKEUP_MASK
 registers

Hi folks,

The following series adds support for programming the gs101
EINT_WAKEUP_MASK registers for the 67 external wakeup interrupts on gpa0 to
gpa11 (alive and far_alive). gs101 differs to previous SoCs in that it has
3 EINT_WAKEUP_MASK registers

EINT_WAKEUP_MASK  0x3A80 EINT[31:0]
EINT_WAKEUP_MASK2 0x3A84 EINT[63:32]
EINT_WAKEUP_MASK3 0x3A88 EINT[66:64]

This is achieved by adding gs101 specific callbacks and a dedicated
gs101_wkup_irq_chip struct which is triggered from the existing
google,gs101-wakeup-eint compatible.

This code path can be tested  using:
echo mem > /sys/power/state

With the functional CPU hotplug, this brings us another step closer to
having functional suspend to RAM upstream.

kind regards,

Peter
