Beside standard suspend-to-RAM state, Zynq MPSoC supports suspend-to-RAM state with additional power savings, called power-off suspend-to-RAM. If this mode is set, only NODE_EXTERN must be set as wake source. Standard suspend-to-RAM procedure is unchanged. This patch adds support for setting suspend mode from higher ELs and ensuring that all conditions for power-off suspend mode are set.
