hwrng: iproc-rng200 - Implement suspend and resume calls

Browse source

[ Upstream commit 8e03dd62e5 ]

Chips such as BCM7278 support system wide suspend/resume which will
cause the HWRNG block to lose its state and reset to its power on reset
register values. We need to cleanup and re-initialize the HWRNG for it
to be functional coming out of a system suspend cycle.
