[PATCH v7 0/2] irqchip: qcom: add support for PDC interrupt controller

From: Lina Iyer
Date: Thu Feb 15 2018 - 16:27:52 EST


Changes since v6:
- Code clean up as suggested by Thomas
- Rebased on top of 4.16-rc1

On newer Qualcomm Techonologies Inc's SoCs like the SDM845, the GIC is in a
power domain that can be powered off when not needed. Interrupts that need to
be sensed even when the GIC is powered off, are routed through an interrupt
controller in an always-on domain called the Power Domain Controller a.k.a PDC.
This series adds support for the PDC's interrupt controller.

Please consider reviewing these patches.
