[PATCH v3 0/3] AMD/Xilinx Versal TRNG support |
Date: |

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.
V2 => V3
1) Patch #1 Use DEFINE_PROP to define a property with custom action on set
2) Patch #1 Remove duplicated version-check on writing to CTRL4 register
3) Patch #2 Defer adding TRNG to machine's device-tree to a future patch
4) Patch #3 Code style fix: group all local vars definitions together
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
