Subject: [PATCH RFC 0/4] irqchip: qcom: add support for PDC interrupt controller

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.

Lina Iyer (4):
  drivers: irqchip: pdc: add support for PDC interrupt controller
  dt-bindings/interrupt-controller: pdc: descibe PDC device binding
  drivers: irqchip: pdc: log PDC info in FTRACE
  drivers: irqchip: qcom: add pin information for SDM845
