tee: optee: discover services dependent on tee-supplicant

2022-12-23T08:26:15Z

Makes OP-TEE to enumerate also services depending on tee-supplicant support in U-Boot. This change allows OP-TEE services like fTPM TA to be discovered and get a TPM device registered in U-Boot.

tee: optee: don't fail probe because of optee-rng

2022-12-23T08:26:11Z

Fixes optee-rng driver bind sequence in optee driver to print a warning message but not report an error status when a optee-rng service driver fails to be bound as the optee driver itself is still fully functional.

drivers: tee: optee: discover OP-TEE services

2022-09-14T19:23:03Z

This change defines resources for OP-TEE service drivers to register themselves for being bound to when OP-TEE firmware reports the related service is supported. OP-TEE services are discovered during optee driver probe sequence which mandates optee driver is always probe once bound. Discovery of optee services and binding to related U-Boot drivers is embedded upon configuration switch CONFIG_OPTEE_SERVICE_DISCOVERY.

drivers: tee: optee: remove unused probe local variable

Removes local variable child in optee_probe() that is not used. Cc: Patrick Delaunay Reviewed-by: Patrick Delaunay Signed-off-by: Etienne Carriere

tee: optee: bind rng optee driver

2022-04-11T14:28:04Z

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. Signed-off-by: Patrick Delaunay

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

2021-07-23T11:13:25Z

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

2021-04-12T21:44:55Z

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.

dm: core: Access device ofnode through functions

2021-01-05T19:24:41Z

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. Signed-off-by: Simon Glass

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

2020-12-13T23:51:09Z

This name is far too long. Rename it to remove the 'data' bits. This makes it consistent with the platdata->plat rename. Signed-off-by: Simon Glass

dm: treewide: Rename dev_get_platdata() to dev_get_plat()

2020-12-13T23:51:09Z

Rename this to be consistent with the change from 'platdata'. Signed-off-by: Simon Glass
