Hello,
This patch series adds initial Device Tree support for Realtek's Kent SoC
family, including the RTD1501S, RTD1861B, and RTD1920S variants with their
respective evaluation boards.
The series includes:
1. Adds compatible strings for the Kent family.
2. Add Device Tree files for the Kent SoC, TD1501S Phantom EVB (8GB),
RTD1861B Krypton EVB (8GB), and RTD1920S Smallville EVB (4GB).
The patches have been validated with 'make dtbs_check' and
'dt_binding_check' to ensure compliance with DT schema and successful
compilation.
Cheers,
Yu-Chun

Changes in v3:
- Drop the dt-bindings patch (realtek,misc.yaml)
- Drop 'iso: syscon@7000' node and and re-parent the UART directly to rbus
- Change all dts/dtsi to license: GPL-2.0
- Drop all custom bootargs
V2: https://lore.kernel.org/lkml/20251113123009.26568-1-eleanor.lin@realtek.com/
Changes in v2:
[PATCH v2 1/3]
- Fix YAML syntax: remove duplicate blank lines
- Validated with 'make dt_binding_check'
[PATCH v2 2/3]
- Rename: realtek,iso-system.yaml -> realtek,misc.yaml
- Improve description and example: show child node (UART)
[PATCH v2 3/3]
- Reorder Makefile targets to alphabetical order.
- Rename node: use generic names ('arch_timer' -> 'timer', 'reg-bus' -> 'bus')
- Fix node naming and hex format (remove leading zeros)
- Inline overlay nodes directly into .dtsi
- Reorder properties: ranges after reg
- Remove unnecessary status and custom bootargs
V1: https://lore.kernel.org/lkml/20251105104452.6336-1-eleanor.lin@realtek.com/

Define compatible strings for Realtek RTD1501s, RTD1861b and RTD1920s.
Additionally, convert legacy DTS-style comments to YAML description
properties, following the pattern from the ARM bindings conversion series
[1].

Hi Krzysztof,
I would like to ask for guidance on how to proceed with this patch.
The listed maintainer for Realtek SoCs, Andreas Färber, seems to be inactive
(no activity since May 2023), and my recent emails to him bounced with
"Undelivered Mail Returned to Sender".
Should I resend this patch and explicitly Cc soc@kernel.org and the ARM SoC
maintainers (e.g., Arnd Bergmann) so it can be picked up directly by the SoC team?
Best regards,
Yu-Chun
