[PATCH RFT v2] arm64: dts: qcom: glymur-crd: Enable WLAN and Bluetooth
From: Abel Vesa
Date: Tue Mar 24 2026 - 11:13:37 EST
Both Glymur and Mahua CRDs feature a WCN7850 M.2 WLAN and Bluetooth
combo card.
So describe both the 0.9V and the 3.3V regulators, then WCN7850 PMU and
the PCIe WLAN and the UART Bluetooth nodes.
Do this in the Glymur CRD generic dtsi so that both Glymur and Mahua CRDs
benefit from it towards enabling WLAN and Bluetooth functionality.

Sending as RFT since I only tested this on Glymur CRD.
As far as I know, Mahua CRD uses the same WCN7850 board, but I do
not have (yet) access to a Mahua CRD to test on.

Changes in v2:
- Rebased on next-20260323.
- Address commit message issue reported by Zijun
- Dropped the vddio1p2-supply as Zijun suggested.
- Did not rework with the M.2 connector since the E Key is still
under review on the list.
- Re-worked so that it is done in the generic CRD dtsi in order
to add the same support for Mahua CRD.
- Link to v1: https://patch.msgid.link/20260309-glymur-dts-crd-enable-bt-wlan-v1-1-3badbddd5439@xxxxxxxxxxxxxxxx
