Subject: [PATCH v3 0/8] Add support for best effort block read emulation

This is version 3 for adding i2c_smbus_read_i2c_block_data_or_emulated
to i2c-core. The i2c core part is the same as in v2, but I have added
3 more users for iio drivers.

Changes in v2:
 - changed bmc150-accel, kxcjk-1013 and bmg160 drivers to use
i2c_smbus_read_i2c_block_data_or_emulated

Changes in v1:
 - dropped the RFC tag
 - changed at24 to use i2c_smbus_read_i2c_block_data_or_emulated
 - when reading an odd number of bytes using word emulation, read an even
number of bytes and drop the last one
 - add a comment that this might not be suitable for all I2C slaves 

Adriana Reus (2):
  iio: accel: kxcjk-1013: use available_scan_masks
  iio: accel: kxcjk-1013: optimize i2c transfers in trigger handler
