[PATCH v3 0/7] riscv: dts: tenstorrent: Add Atlantis platform

[Joel Stanley]

Add initial support for the Tenstorrent Atlantis platform, based on the
Atlantis SoC featuring 8x RVA23-compliant Tenstorrent Ascalon-XG cores.

The series adds a bare bones device tree with the CPU, interrupt
controllers and a UART.

Patches 1, 2, 3, 5, and 6 add compatibles or extensions to existing
bindings.

Patch 4 adds a binding for the aclint timer device, with a new rationale
for including it following discussion with Conor at Plumbers.

The series has been boot tested on QEMU and internal development
platforms.

v2:
https://lore.kernel.org/linux-riscv/20260604143957.668047-1-joel@jms.id.au/

Changes since v2:
 - Fixes to prcm_rcpu and aplic dt nodes
 - Drop uart1 clock override. UART now depends on a working PRCM driver
 - Drop bootargs console=ttyS0 in favour of stdout-path
 - Justify aclint mtimer bindings

Changes since v1:
 - Rework mtimer bindings, fix reg property, update compatible and use
   priv spec as reference
 - Drop Drew's sob from bindings patches I wrote
 - Add Drew's co-developed-by to dts patch
 - Correct aplic num-sources
