[PATCH v3 0/4] regmap: i2c block support

Hi,

This series adds support for i2c block read/writes. To support the maximum 32
byte read/write operations, the regmap core is extended by max_raw_read and
max_raw_write. bulk operations are splitted depending of the size of
max_raw_read/write.

The last patch needs testing before it can be applied.

Best Regards,

Markus


Changes in v3:
- Rebased onto latest version of "regmap: fixes" series

Changes in v2:
- max_raw_io splitted into max_raw_read/write
- Use E2BIG as error value in the block read/write functions

Markus Pargmann (4):
  regmap: Introduce max_raw_read/write for regmap_bulk_read/write
  regmap: regmap max_raw_read/write getter functions
  regmap: Add raw_write/read checks for max_raw_write/read sizes
  regmap-i2c: Add smbus i2c block support
