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

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.

Alain Volmat (7):
  i2c: stm32f7: perform most of irq job in threaded handler
  i2c: stm32f7: simplify status messages in case of errors
  dt-bindings: i2c: document st,stm32mp25-i2c compatible
  i2c: stm32f7: add support for stm32mp25 soc
  arm64: dts: st: add all 8 i2c nodes on stm32mp251
  arm64: dts: st: add i2c2/i2c8 pins for stm32mp25
  arm64: dts: st: add i2c2 / i2c8 properties on stm32mp257f-ev1
