On a numer of Exynos-based boards Linux kernel is running in non-secure mode under a secure firmware. This means that certain operations need to be handled in special way, with firmware assistance. System-wide suspend/resume is an example of such operations. This patch adds support for firmware-assisted suspend/resume by leveraging recently introduced suspend and resume firmware operations and modifying existing suspend/resume paths to account for presence of secure firmware.
