[PATCH v4 0/4] Add support for vibrator motor for TBS A711 Tablet

[Ondrej Jirman]

The tablet has a vibrator motor. This patch series exposes it via
input subsystem (EV_FF).

I'd like to ask input maintainers to take the patches 1 and 2.
Patches 3 and 4 should go via the sunxi tree.

The change to the vibrator driver is meant to enable toggling the
vibrator motor just via a power supply itself. There's not additional
gpio driven switch on this tablet between the power supply for the
motor and the motor.

Please take a look.

Changes in v4:
- Added DT reviewed-by tag
- Fixed motor typo

Changes in v3:
- Changed dt-binding to require at least one of enable/supply, dropped ack
- Changed driver to bail out if neither supply nor gpio is given

Changes in v2:
- Added DT ack tag
- Add more information to the commit log (re use of LDO for the power)


thank you and regards,
  Ondrej Jirman
