If the TRNG has been unretained, it's not sufficient to enable the clock, it must be fully reinitialized. This is a minimal fix to ensure entropy is accumulated after sleep. Long term, this driver should be made to use device power management with power domain awareness. Signed-off-by: Aksel Skauge Mellbye <[email protected]>
