Subject: [PATCH v3 0/3] sun8i-a83t: Add touchscreen support on TBS A711

Hello everyone,

This is a V3 of the patch series that adds touchscreen support
(FocalTech EDT-FT5x06 Polytouch) for TBS A711 (Allwinner sun8i-a83t SoC).
Based on last master of linux-input tree.

Since I can't test the suspend/resume functions there is no updates in
this series about factory/normal mode.

Changes since v2:
   - Remove the check if regulator is NULL (Dmitry Torokhov's review)
   - Add EPROBE_DEFER error not to print a error message (Lothar Waßmann's review)
   - Add set wake/reset on suspend/resume.
Changes since v1:
   - Remove patches 01 and 02 as Chen-Yu Tsai sent a similar patch:
   https://patchwork.kernel.org/patch/10111431/
   and it is merged on last next-20171222.
   (See commit f066f46ce5a5 "ARM: dts: sun8i: a83t: Add I2C device nodes and pinmux settings")
   - Update regulator according to Dmitry Torokhov's review: remove "optional"
   suffix while retrieving the regulator, rename it into "vcc" instead of
   "power" and add bindings documentation.
   - Update device tree according to Maxime Ripard's review: remove the
   label and rename the node.
   - Squash patch 03 with patch 05 to add I2C0 and touchscreen's node
   in one patch (see patch 02).

Patch 01: Add support for regulator in the FocalTech touchscreen driver
because A711 tablet is using a regulator to power-up the touchscreen.
Patch 02: Add a set wake/reset values on resume and suspend.
Patch 03: Add i2c0 and touchscreen's node for A711 TBS tablet.

Thank you in advance for any review.
Best regards,
Mylène
