Bartłomiej Maryńczak 293c485cba HID: i2c-hid: Delayed i2c resume wakeup for 0x0d42 Goodix touchpad
Patch for Goodix 27c6:0d42 touchpads found in Inspiron 5515 laptops.

After resume from suspend, one can communicate with this device just fine.
We can read data from it or request a reset,
but for some reason the interrupt line will not go up
when new events are available.
(it can correctly respond to a reset with an interrupt tho)

The only way I found to wake this device up
is to send anything to it after ~1.5s mark,
for example a simple read request, or power mode change.

In this patch, I simply delay the resume steps with msleep,
this will cause the set_power request to happen after
the ~1.5s barrier causing the device to resume its event interrupts.

Sleep was used rather than delayed_work
to make this workaround as non-invasive as possible.

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 reStructuredText 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.
