| Series | PSP TEE driver update and bug fixes | expand |
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. Third patch is to update the copyright year for the tee driver files.
