[PATCH RFC v2 0/3] irqchip: qcom: add support for PDC interrupt controller

[Lina Iyer]

Changes in v2:
- Drviers will specify PDC pin as their interrupt and PDC as interrupt parent
- Updated driver to pick up PDC pin mappings from DT
- Cleanup driver per Marc's suggestions
- Addressed DT bindings comments from Rob H
- Addressed FTRACE comments from Steven R

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.
