There are devices that need to handle block transactions
regardless of the capabilities exported by the adapter.
For performance reasons, they need to use i2c read blocks
if available, otherwise emulate the block transaction with word
or byte transactions.
Add support for a helper function that wo
For i2c busses that support only SMBUS extensions, the eeprom at24
driver reads data from the device using the SMBus block, word or byte
read protocols depending on availability.
Replace the block read emulation from the driver with the
i2c_smbus_read_i2c_block_data_or_emulated call from i2c core.
This is the second version for adding i2c_smbus_read_i2c_block_data_or_emulated
to i2c-core. It contains mostly fixes suggested by Wolfram.
Changes since 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 em

Lee,
This question is actually more about MFD. Can you point me to the possible

This adds calls to pinctrl subsystem in order to switch pin states
on suspend/resume if you provide a "sleep" state in DT.

Linus,
here are two buildfixes for I2C based on your tree from the day before
yesterday. Sadly, these build errors never reached me while the patches
were sitting in -next. Need to fix that. Please pull.
Thanks,
