@jneuhauser, are you okay with this change? |
Change STM32 I2C driver to rely on the compatible DT property of the node to store whether the bus is expected assigned to secure or non-secure world. Using a non-secure I2C bus in OP-TEE on stm32mp1 platforms is something expected only on STM32MP15 variant for compatibility with platform already supported in upstream Linux/U-Boot components, as defined by st,stm32mp15-i2c-non-secure specific compatible string ID.

Update STM32 I2C driver use st,stm32mp15-i2c-non-secure specific DT compatible property for when the I2C bus is non-secure. Update STM32MP15 based DH boards accordingly.
