Subject: [PATCH v2 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.
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
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
