Ho, Tong Sept. 22, 2023, 6:50 a.m. UTC 
This series adds support for the True Random Number Generator
(TRNG) in the AMD/Xilinx Versal family of devices.

The series starts by introducing a non-cryptographic grade model
of the TRNG controller in the Versal family of devices, followed
by instantiating the model in Xilinx Versal machine.

The series ends with a q-test for sanity check of the TRNG model
in the Xilinx Versal machine.

V1 => V2
1) Change patch #1 only
2) Use g_rand_*() PRNG from glib to replace V1's custom PRNG.
3) Implement ResettableClass for device-reset.
4) Add device-mode description to commit-message.

Best regards,
Tong Ho
