What is the purpose of this software queue? Why can't you directly
feed the requests to the hardware?
If the hardware can't handle more than 50 requests

Currently, the driver enqueues a request only if the busy bit is
false. And every request initiates a dequeue. If 2 requests arrive
simultaneously, only one of them will be dequeued.
To avoid this senario, we will enqueue the next request irrespective
of the system condition (that is what queue

This patch uses the platform_get_irq() instead of the

as resource 0 and hash interrupt as 1.
reasons for this change.
1. Cannot find any Arch which is currently using this driver
2. Samsung Exynos4 and 5 SoCs only use the feeder control

Hi Theodore,
I am not too convinced of RDRAND due to the lack of usable source code

The problem is the FIPS validation would presumably require obeying
