Subject: [PATCH v3 0/3] Add ST lsm6dso i3c support

This patch series add i3c support for STM LSM6DSO and LSM6DSR sensors.

It is also introduced i3c support on regmap api. Due the lack of
i3c devices HDR capables on the market the support for now is only for
i3c sdr mode by using i3c_device_do_priv_xfers() method.

The i3c regmap api is already available in the Git repository at:
  https://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap.git
  tags/regmap-i3c

Change in v3:
  Update st_lsm6dsx_probe() call
  Remove i3c_get_device_id() and use i3c_device_match_id()

Changes in v2:
  Change i3c_get_device_id() to drivers/i3c/device.c
  Add support for LSM6DSR

Vitor Soares (3):
  regmap: add i3c bus support
  i3c: add i3c_get_device_id helper
  iio: imu: st_lsm6dsx: add i3c basic support for LSM6DSO and LSM6DSR
