Subject: [PATCH v4 0/2] irqchip: qcom: add support for PDC interrupt controller
Date: Wed, 7 Feb 2018 08:49:56 -0700 [thread overview]
Message-ID: <20180207154958.13421-1-ilina@codeaurora.org> (raw)
Changes since v3:
- Code clean up as suggested by Marc
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.
