2018-07-02platform/x86: Rename silead_dmi to touchscreen_dmiHans de Goede
Not only silead touchscreens need some extra info not available in the ACPI tables to work properly. X86 devices with a Chipone ICN8505 chip also need some DMI based extra configuration. There is no reason to have separate dmi config code per touchscreen controller vendor. This commit renames silead_dmi to a more generic touchscreen_dmi name (and Kconfig option) in preparation of adding info for tablets with an ICN8505 based touchscreen. Note there are no functional changes all code changes are limited to removing references to silead where these are no longer applicable.

2018-07-02platform/x86: silead_dmi: Sort entries alphabeticallyHans de Goede
We have so much entries now that it is good to bring some form of order to them. This should also reduce conflicts when multiple patches make changes at the same time (compared to tagging all new entries at the end). Note this commit purely moves stuff around and adds 2 comments about keeping the data and table alphabetically sorted. There are no functional changes.

Note that we already have an entry for the Point of View mobii TAB-P800W (v2.1), that version uses a different digitizer and different firmware, so the v2.0 version needs its own entry.

Add an entry with touchscreen info for the Yours Y8W81 8" tablet. This tablet has the same case and mostly the same internals as the Chuwi Vi8. Both seem to be from an ODM called inet-tek. Both are labelled: "INET-I86M-REVxx" on the PCB, with the Chuwi Vi8 being REV03 (and having an ALC5640 audio codec) and the Yours Y8W81 being REV21 (and having an ALC5651 audio codec). The wifi, accelerometer and touchscreen are identical on both. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com>

2017-11-03platform/x86: silead_dmi: Fix GP-electronic T701 entryHans de Goede
The GP-electronic T701 has its LCD panel mounted upside-down, initially my plan was to fix this by transparently rotating the image in the i915 driver (my "drm/i915: Deal with upside-down mounted LCD" patch), but that approach has been rejected instead the kernel will now export a "panel orientation" property on the drm-connector for the panel and let userspace deal with it. But userspace expects the touchscreen coordinates to match the panel coordinates *before* applying any rotation, so now that we no longer hide the upside-down-ness of the LCD panel from userspace the coordinates being generated are wrong and we need to apply a rotation of 180 degrees to the coordinates to fix this.
