Subject: [PATCH 0/9] qcom: ssbi-gpio: add support for hierarchical IRQ chip
Date: Fri, 25 Jan 2019 11:22:53 -0500 [thread overview]
Message-ID: <20190125162302.14036-1-masneyb@onstation.org> (raw)
This patch series adds hierarchical IRQ chip support to ssbi-gpio so
that device tree consumers can request an IRQ directly from the GPIO
block rather than having to request an IRQ from the underlying PMIC.
For more background information, see the email thread with Linus
Walleij's excellent description of the problem at
https://www.spinics.net/lists/linux-gpio/msg34655.html.
This change was not tested on any actual hardware, however the same
change was made to spmi-gpio and tested on a LG Nexus 5 (hammerhead)
phone. That patch series is available at
https://lore.kernel.org/lkml/20190119204252.18370-1-masneyb@onstation.org/
and is queued for the next merge window.
