Subject: [PATCH v2 2/5] dt-bindings: pinctrl: add wakeup capable GPIOs for SDM845
Date:   Fri, 24 Aug 2018 14:01:54 -0600
Message-Id: <20180824200157.9993-3-ilina@codeaurora.org>
In-Reply-To: <20180824200157.9993-1-ilina@codeaurora.org>
References: <20180824200157.9993-1-ilina@codeaurora.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Update the documentation to use interrupts-extended format for
specifying the TLMM summary IRQ line that is requested from GIC and the
PDC interrupts corresponding to the wakeup capable GPIOs.

Update the example to show PDC interrupts for the wakeup capable GPIOs
for SDM845.
