[PATCH v2 0/2] Add Model for Tenstorrent Atlantis PRCM

This series adds a qemu model for the PRCM blocks present in Tenstorrent
Atlantis. This block controls clock, reset and other misc functionality
in the SoC. Linux support for the Clocks/Resets served by the RCPU PRCM
was added in [1]. This PRCM model has been tested with a linux DT that
enables the PRCM and sets the UART clk to the one provided by the PRCM.
This DT will be sent out shortly.
