Subject: [PATCH v2 4/8] dt-bindings: sdm845-pinctrl: add wakeup interrupt parent for GPIO
Date: Thu, 24 Jan 2019 13:22:01 -0700	[thread overview]
Message-ID: <20190124202205.7940-5-ilina@codeaurora.org> (raw)
In-Reply-To: <20190124202205.7940-1-ilina@codeaurora.org>

SDM845 SoC has an always-on interrupt controller (PDC) with select GPIO
routed to the PDC as interrupts that can be used to wake the system up
from deep low power modes and suspend.
