Subject: [PATCH v2 0/6] i2c: mpc: Refactor to improve responsiveness

The "meat" of this series is in the last patch which is the change that
actually starts making use of the interrupts to drive a state machine.
The dt-bindings patches can probably go in at any time, the rest of the
series isn't dependent on them.

I've tested on T2081 and P2041 based systems with a number of i2c and smbus
devices.

Chris Packham (6):
  dt-bindings: i2c-mpc: Document interrupt property as required
  dt-bindings: i2c: convert i2c-mpc to json-schema
  i2c: mpc: Make use of i2c_recover_bus()
  i2c: mpc: make interrupt mandatory and remove polling code
  i2c: mpc: use device managed APIs
  i2c: mpc: Interrupt driven transfer
