Hi Stephen,

This pull request introduces support for the Tenstorrent Atlantis RISC-V
SoC in the form of a clk driver, reset driver and the associated DT
binding. The reset driver was reviewed by Philipp, who agreed that it
could go via the clk tree. Brian reviewed the clk driver but there is no
review/ack from you. Please let me know if you'd like to see any changes
and we will post a new revision.

The following changes since commit 6de23f81a5e08be8fbf5e8d7e9febc72a5b5f27f:

  clk: tenstorrent: Add Atlantis clock controller driver (2026-03-09 20:10:26 -0700)

----------------------------------------------------------------
clk: tenstorrent: Add support for Atlantis PRCM

Introduce support for the clock and reset controllers (e.g. PRCM) in the
Tenstorrent Atlantis SoC. 5 types of clocks are generated by the PRCM:
PLLs, shared gates and standard muxes. The reset controller is setup as
an auxiliary device of the clock controller.
