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:
v3: - addition of 2 commits dealing with readl_relaxed(I2C_ISR) in
isr handler and a second one to use dev_err_probe during probe
- correction of SOB in commit
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

DT patches applied on stm32-next. Not that I added acces-controller
bindings for all I2C nodes.
Thanks!
