[PATCH v2 0/5] DRV260x: Support ACPI-enumerated devices

[Yauhen Kharuzhy]

Lenovo Yoga Book YB1-X90 and YB1-X91 tablets use haptics controllers
DRV2604L. The X91 (Windows tablet) uses ACPI to define its configuration,
such as I2C address and GPIO connections. The X90 (Android tablet)
doesn't have it in the ACPI, but the device may be defined as an
i2c_board in the x86-android-tablets driver.

To support these variants, add an ACPI matching table and add additional
I2C IDs to the I2C matching table (the driver supports DRV2604(L),
DRV2605(L) devices).

Also, implement a timeout for waiting for calibration,
and fix the non-working suspend due to unbalanced regulator_disable() call.

Changes in v2:
- Header includes have been sorted alphabetically;
- ACPI GPIO mapping has been removed (supposed to be in the
  device-specific driver like x86-android-tablets);
- Old debug session artifacts removed;
- Checking of device ID has been removed; the driver uses the same logic
  for all drv260x(L) variants;
- Timeout during calibration reports an error; we don't expect that
  the chip will work properly in such a case;
- Patch regarding the regulator has been reworked; now it just adds
  regulator_enable()/regulator_disable() during device probing and removal.

Discussion of v1 is here:
