Enable BT on qcs8300-ride by adding a BT device tree node.
Since the platform uses the QCA6698 Bluetooth chip. While
the QCA6698 shares the same IP core as the WCN6855, it has
different RF components and RAM sizes, requiring new firmware
files. Use the firmware-name property to specify the NVM and
rampatch firmware to load.

This patch depends on:
- WLAN
https://lore.kernel.org/all/20260122053624.4068718-1-wei.zhang@oss.qualcomm.com/
Changes in v3:
- Rebase patches
- Remove unintended 'output-low' from bt-en-state pinctrl
- Use prerequisite-message-id to replace prerequisite-patch-id (Konrad)
- Link to v2: https://lore.kernel.org/all/20251118140406.1551669-2-wei.deng@oss.qualcomm.com/
Changes for v2
- Update commit message, add firmware name detail
- Reorganize patchset
- Link to v1: https://lore.kernel.org/all/20251113130942.2661069-1-wei.deng@oss.qualcomm.com/

Send one complete Bluetooth+WLAN posting. Thanks for the clarification. The WLAN patch has just been reposted as a new v10: https://lore.kernel.org/all/20260225071459.1600394-1-wei.zhang@oss.qualcomm.com/ This v10 no longer depends on the additional patches mentioned earlier. Given this update, would it be acceptable if I re-submit the Bluetooth patch on top of this v10 WLAN change? > > Best regards, > Krzysztof -- Best Regards, Wei Deng

Only now did I realize you're the author of both patches!
Next time around, please keep them in the same series, for easier
tracking (since they're very much related)

Ideally there'd be a newline separating the properties from the subnodes

Just to clarify — are you referring to the below WLAN-related patch and this one?
https://lore.kernel.org/all/20260122053624.4068718-1-wei.zhang@oss.qualcomm.com/
If so, they are authored by different people. This BT-related patch depend on it.
