[PATCH v2 4/8] dt-bindings: sdm845-pinctrl: add wakeup interrupt parent for GPIO

From: Lina Iyer <hidden>
Date: 2019-01-24 20:22:28
Also in: linux-arm-msm, lkml
Subsystem: arm/qualcomm mailing list, open firmware and flattened device tree bindings, pin control subsystem, pin controller - qualcomm, the rest · Maintainers: Rob Herring, Krzysztof Kozlowski, Conor Dooley, Linus Walleij, Bjorn Andersson, Linus Torvalds

SDM845 SoC has an always-on interrupt controller (PDC) with select GPIO
routed to the PDC as interrupts that can be used to wake the system up
from deep low power modes and suspend.
