Subject: [PATCH v3 0/9] i2c: stm32f7: enhancements and support for stm32mp25
Date: Fri, 15 Dec 2023 18:06:04 +0100

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

Alain Volmat (9):
  i2c: stm32f7: use dev_err_probe upon calls of devm_request_irq
  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: perform I2C_ISR read once at beginning of event isr
  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
