Subject: [PATCH v3 0/2] hwrng: npcm: add NPCM RNG driver support
Date:   Thu, 12 Sep 2019 12:01:47 +0300

This patch set adds Random Number Generator (RNG) support 
for the Nuvoton NPCM Baseboard Management Controller (BMC).

The RNG driver we use power consumption when the RNG 
is not required.

The NPCM RNG driver tested on NPCM750 evaluation board.

Addressed comments from:.

Changes since version 2:
 - Rearrange wait parameter in npcm_rng_read function.
 - Calling pm_runtime_enable function before hwrng_register function 
   called to enable the hwrng before add_early_randomness called.
 - Remove quality dt-binding parameter in the driver and documentation.
 - Disable CONFIG_PM if devm_hwrng_register failed.
 - Remove owner setting in the driver struct.

Changes since version 1:
 - Define timout in real-world units.
 - Using readl_poll_timeout in rng_read function.
 - Honor wait parameter in rng_read function.
 - Using local variable instead of #ifndef.
 - Remove probe print.
