Andreas Kemnade 20bb907f7d mfd: twl-core: Disable IRQ while suspended
Since commit 6e2bd956936 ("i2c: omap: Use noirq system sleep pm ops to idle device for suspend")
on gta04 we have handle_twl4030_pih() called in situations where pm_runtime_get()
in i2c-omap.c returns -EACCES.

[   86.474365] Freezing remaining freezable tasks ... (elapsed 0.002 seconds) done.
[   86.485473] printk: Suspending console(s) (use no_console_suspend to debug)

[   86.555664] Successfully put all powerdomains to target state
[   86.563720] twl: Read failed (mod 1, reg 0x01 count 1)
[   86.563751] twl4030: I2C error -13 reading PIH ISR
[   86.563812] twl: Read failed (mod 1, reg 0x01 count 1)
[   86.563812] twl4030: I2C error -13 reading PIH ISR
[   86.563873] twl: Read failed (mod 1, reg 0x01 count 1)
[   86.563903] twl4030: I2C error -13 reading PIH ISR

This happens when we wakeup via something behing twl4030 (powerbutton or rtc
alarm). This goes on for minutes until the system is finally resumed.
Disable the irq on suspend and enable it on resume to avoid
having i2c access problems when the irq registers are checked.

README

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.

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.
