Not that I added acces-controller bindings for all I2C nodes. Thanks! Alex
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 .../devicetree/bindings/i2c/st,stm32-i2c.yaml | 28 ++ arch/arm64/boot/dts/st/stm32mp25-pinctrl.dtsi | 36 ++ arch/arm64/boot/dts/st/stm32mp251.dtsi | 96 +++++ arch/arm64/boot/dts/st/stm32mp257f-ev1.dts | 20 + drivers/i2c/busses/i2c-stm32f7.c | 342 +++++++++--------- 5 files changed, 358 insertions(+), 164 deletions(-)
