thermal/debugfs: replace kzalloc() with kcalloc() in thermal_debug_tz_add()
Work is under way to get rid of all multiplications from allocation functions to prevent integer overflows [1]. Here the multiplication is obviously safe, but using kcalloc() is more appropriate and improves readability. This change has no effect on runtime behavior.

light'> Add a new CCP/PSP PCI device ID and corresponding entry in the dev_vdata struct. Signed-off-by: John Allen <john.allen@amd.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> 2021-08-06crypto: ccp - shutdown SEV firmware on kexecBrijesh Singh The commit 97f9ac3db6612 ("crypto: ccp - Add support for SEV-ES to the PSP driver") added support to allocate Trusted Memory Region (TMR) used during the SEV-ES firmware initialization. The TMR gets locked during the firmware initialization and unlocked during the shutdown. While the TMR is locked, access to it is disallowed. Currently, the CCP driver does not shutdown the firmware during the kexec reboot, leaving the TMR memory locked. Register a callback to shutdown the SEV firmware on the kexec boot.

They also need to take care of standard configuration registers. Switch to generic power management framework using a single "struct dev_pm_ops" variable to take the unnecessary load from the driver. This also avoids the need for the driver to directly call most of the PCI helper functions and device power state control functions as through the generic framework, PCI Core takes care of the necessary operations, and drivers are required to do only device-specific jobs.

Raven Ridge is an APU with a dedicated AMD Secure Processor having Trusted Execution Environment (TEE) support. The TEE provides a secure environment for running Trusted Applications (TAs) which implement security-sensitive parts of a feature. This patch configures AMD Secure Processor's TEE interface by initializing a ring buffer (shared memory between Rich OS and Trusted OS) which can hold multiple command buffer entries. The TEE interface is facilitated by a set of CPU to PSP mailbox registers. The next patch will address how commands are submitted to the ring buffer.
