Tony Lindgren 35c3c196d3 power: bq24190_charger: Check the interrupt status on resume
Some SoCs like omap3 can configure GPIO irqs to use Linux generic
dedicated wakeirq support. If the dedicated wakeirq is configured,
the SoC will use a always-on interrupt controller to produce wake-up
events.

If bq24190 is configured for dedicated wakeirq, we need to check the
interrupt status on PM runtime resume. This is because the Linux
generic wakeirq will call pm_runtime_resume() on the device on a
wakeirq. And as the bq24190 interrupt is falling edge sensitive
and only active for 250 us, there will be no device interrupt seen
by the runtime SoC IRQ controller.

Note that this can cause spurious interrupts on omap3 devices with
bq24190 connected to gpio banks 2 - 5 as there's a glitch on those
pins waking from off mode as listed in "Advisory 1.45". Devices
with this issue should not configure the optional wakeirq interrupt
in the dts file.

README

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
