Subject: [PATCH v3 0/2] irqchip: qcom: add support for PDC interrupt controller

Changes since RFC v2:
- Fixed up DT probe based on suggestions from Thomas and Marc
- Code clean up as suggested by Thomas
- Switch to SPDX license marker
- Dropped the FTRACE patch for now, will need more thought and discussions

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.
