Maulik Shah 657d3fdc70 ANDROID: GKI: genirq: Introduce irq_chip_get/set_parent_state calls
On certain QTI chipsets some GPIOs are direct-connect interrupts
to the GIC.

Even when GPIOs are not used for interrupt generation and interrupt
line is disabled, it does not prevent interrupt to get pending at
GIC_ISPEND. When drivers call enable_irq unwanted interrupt occures.

Introduce irq_chip_get/set_parent_state calls to clear pending irq
which can get called within irq_enable of child irq chip to clear
any pending irq before enabling.

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

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

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.
