[PATCH 0/8] optee: add bidirectional communication support

[Ahmad Fatoum]

So far, barebox interaction by OP-TEE was limited to loading it and
maybe passing along its device tree fixup. In some scenarios, there
is a lot more that could need to be done however:

  - Access to eMMC RPMB memory
  - Access to keys stored in OP-TEE, e.g. in Trusted Keys TA or
    in fTPM
  - Access to hardware managed by OP-TEE via e.g. PRNG TA

Let's prepare for all that by importing the Linux v6.6 OP-TEE support
into barebox. This series has been tested on STM3MP15 and STM32MP13
32-bit ARM SoCs, where OP-TEE functioned as SCMI provider, restricting
access to some clocks, resets and regulators deemed too important to
let pesky normal world have direct access to them.

Ahmad Fatoum (5):
  driver: don't clear unrelated struct device_node::device on unregister
  deep-probe: don't panic when device can't be created
  deep-probe: skip on-demand platform dev creation for nodes without
    compatible
  devinfo: indicate if device tree nodes are differently populated
  hw_random: add implementation for OP-TEE RNG pseudo TA

Marc Kleine-Budde (3):
  include: uaccess.h: import from linux
  optee: add bidirectional communication support
  optee: add experimental support for /dev/tee0
