The goal of this series is to add I2C support to ST SoCs.
The DT definition is added for STiH415 and STiH416 SoCs on
B2000 and B2020 boards.
The series has been tested working on STiH416-B2020 board.
It applies on top of v3.12-rc1.
Changes since v1:
- Anti-glitch filtering simplified (Only HW Anti-glitch is kept)
- Update I2C timings to comply with I2C specification
- Handle spurious interrupts properly
- DT binding updates taking into account Stephen's comments
- Use "clock-names" property to comply with GCF
- DT cosmetic changes reported by Lee and Gabriel
