Examples for STM made OP-TEE drivers?

[Fee]

Hi all,

i want to use some hardware peripherals in OP-TEE. I got the GPIO driver (stm32_gpio in core/drivers) to work with my PTA (Pseudo Trusted Application). I now wanna use the I2C peripheral using the stm32_i2c driver.

I coundn't find any example code (for the GPIO neither), is there somewhere an example of how to use the drivers from a PTA?

EDIT: I was able to configure the I2C peripheral with the driver, i missed the GPIO configuration. Some documentation of the OP-TEE drivers would be a nice feature for the future nevertheless =)
