tee: optee: bind rng optee driver

2022-04-11T14:28:04+00:00

In U-Boot, the discovery of TA based on its UUID on the TEE bus is
not supported.

This patch only binds the driver associated to the new supported
OP-TEE TA = TA_HWRNG when this driver is enable.

tee: optee: sync cache on pre-reloc OP-TEE invocation

2021-07-23T11:13:25+00:00

This change ensures both U-Boot and OP-TEE see the same content
from shared memory when OP-TEE is invoked prior U-Boot relocation.

This change is required since U-Boot may execute with data cache off
while OP-TEE always enables cache on memory shared with U-Boot.

tee: optee: Change printing during optee_probe

2021-04-12T21:44:55+00:00

Right now the error messages when optee has a version mismatch or shared
memory is not configured are done with a debug().
That's not very convenient since you have to enable debugging to figure
out what's going on, although this is an actual error.

So let's switch the debug() -> dev_err() and report those explicitly.

drivers: tee: i2c trampoline driver

2021-02-16T16:48:20+00:00

This commit gives the secure world access to the I2C bus so it can
communicate with I2C slaves (typically those would be secure elements
like the NXP SE050).

A similar service implementation has been merged in linux:
c05210ab ("drivers: optee: allow op-tee to access devices on the i2c
bus")

dm: core: Access device ofnode through functions

2021-01-05T19:24:41+00:00

At present ofnode is present in the device even if it is never used. With
of-platdata this field is not used, so can be removed. In preparation for
this, change the access to go through inline functions.

dm: treewide: Rename ofdata_to_platdata() to of_to_plat()

2020-12-13T23:51:09+00:00

This name is far too long. Rename it to remove the 'data' bits. This makes
it consistent with the platdata->plat rename.
