[PATCH v2 0/2] PSP TEE driver update and bug fixes

From: Rijo Thomas
Date: Tue Mar 09 2021 - 23:45:43 EST


The first patch helps to improve the response time by reducing the
polling time of the tee command status variable.

Second patch is a bug fix to handle multi-threaded use-case.
During testing, race condition was seen due to missing synchronisation
in writes to the TEE ring buffer. This patch helps to resolve that.

v2:
* Updated copyright year as a part of code change

Rijo Thomas (2):
crypto: ccp - reduce tee command status polling interval from 5ms to
1ms
crypto: ccp - fix command queuing to TEE ring buffer
