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

It is also introduced i3c support on regmap API. Due to the lack of
i3c devices with HDR feature 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 v6:
  Improve kerneldoc

Change in v5:
  Remove regmap-i3c patch, already applied in regmap tree
  Fix warning when compiling in 64-bit architecture

Change in v4:
  remover hw_id variable from st_lsm6dsx_i3c_probe()

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 (2):
  i3c: add i3c_get_device_id helper
  iio: imu: st_lsm6dsx: add i3c basic support for LSM6DSO and LSM6DSR
