> The FU540-C000 support in U-Boot is missing DM based reset driver, and is

> The series here adds a generic DM reset driver for SiFive SoC's so as to leverage

> Patch 1: Add necessary dt indexes for device reset register.
> Patch 2: Update macro's to use common dt indexes from binding header.
> Patch 3: Add reset producer and consumer entries within the device tree.
> Patch 4: Add reset dm driver and bind it within prci module.
> Patch 5: Add Kconfig, Makefile entries and enable the driver

A gentle reminder to pull in this series.

Thanks & BR,
