Subject: [PATCH v3 0/2] iio: vncl4000: Enable runtime pm for vcnl4200/4040

This is modelled after the vcnl4035 driver. For the vcnl40{0,1,2}0
we don't do anything since they use on demand measurement.

Changes from v2
---------------
- Based on review feedback from Jonathan Cameron

  - Fix missing return statement
  - Only update timestamp on power on
  - simplify returns from vcnl4200_runtime_suspend
- simplify return from vcnl4000_init

Changes from v1

- Based on review feedback from Tomas Novotny
  https://lore.kernel.org/linux-iio/20200120182853.37a724fa@tomas.local.tbs-biometrics.cz/
  Drop long wait in vcnl4000_runtime_resume but rather
  use vcnl4200_{al,ps}.last_measurement to make sure
  we wait long enough.

Guido Günther (2):
  iio: vcnl4000: Use a single return when getting IIO_CHAN_INFO_RAW
  iio: vncl4000: Enable runtime pm for vcnl4200/4040
