Hello,

this is v4 of my "Input: goodix - add axis swapping and axis inversion
support" patchset.

The goodix touchscreen driver has gained device-tree support in kernel
4.1, but doesn't currently support the touchscreen-swapped-x-y,
touchscreen-inverted-x and touchscreen-inverted-y properties.
On systems which combine a portrait-mode display with a landscape-mode
touchscreen, such as e.g. the MSI Primo 81 tablet, support for these
features is necessary to have the touchscreen and the display use the
same coordinate system.

With support for axis inversion, the "rotated_screen" flag in the
driver can also be removed, as "rotated_screen" is just a special case
of x/y axis inversion.

This patchset sits on top of the "[PATCH v11 0/8] Goodix touchscreen
enhancements" series by Irina Tirdea:
https://www.spinics.net/lists/linux-input/msg42146.html

The axis swapping has successfully been tested on an MSI Primo 81
tablet and on a Wexler TAB7200 tablet; the x/y inversion resp. 
the rotated_screen functionality has successfully been tested on
a WinBook TW100.

Folded 3 into 1 and applied everything, see my goodix branch.

Thanks.
