| |
Add the necessary device tree node for qcom,prng-ee so we can use the hardware random number generator. This functionality was tested on a SA8540p automotive development board using kcapi-rng from libkcapi.
Signed-off-by: Brian Masney <bmasney@redhat.com> --- Changes from v2 to v3: - Correctly sort node by MMIO address
Patch introduced in v2
