[RFC PATCH 03/17] crypto: caam: Blacklist CAAM when kexec is enabled
From: Scott Wood <hidden>

This driver hangs the kernel on boot when loaded via kexec. To make this driver kexec-safe, add a suspend or freeze hook, and when probing, don't make any assumptions about the existing hardware state (e.g. don't request_irq before quiescing the device).
