Subject: [PATCH v2 0/3] hwrng: starfive - Add driver for TRNG module

This patch series adds kernel support for StarFive hardware random
number generator. First 2 patches add bindings documentation and driver
for this module. Patch 3 adds devicetree entry for VisionFive v2 SoC.

Patch 3 needs to be applied on top of:
https://patchwork.kernel.org/project/linux-riscv/patch/20221220011247.35560-7-hal.feng@starfivetech.com/

Changes since v1:
- updated of_match_ptr and added pm_sleep_ptr in Patch 2. (by Krzysztof)
- drop "status" in dts as module is always on in Patch 3. (by Krzysztof)
