[PATCH v2 0/7] i2c: stm32f7: enhancements and support for stm32mp25

[Alain Volmat]

This series first perform enhancements in the way interrupt are handled
and cleanup in messages.
Then it adds support for the stm32mp25 which differs in that
it only has a single irq line for both event/error and has a
different handling of the FastModePlus.
Support is then enabled within the stm32mp25 related device-trees.

Changelog:
v2: - correct st,stm32-i2c.yaml.  Use if then else scheme to indicate
      number of interrupts / interrupt-names depending on the
      compatible while keeping the description within the common part

    - correct 2 maybe-uninitialized warnings
          * ret in stm32f7_i2c_write_fm_plus_bits
          * irq_error in stm32f7_i2c_probe, move the platform_get_irq
            within the same if block as devm_request_threaded_irq

  i2c: stm32f7: perform most of irq job in threaded handler
  i2c: stm32f7: simplify status messages in case of errors
