[PATCH] arm64: dts: qcom: glymur-crd: Enable WLAN and Bluetooth
From: Abel Vesa
Date: Mon Mar 09 2026 - 13:33:47 EST
The Glymur CRD features a WCN7850 WLAN and Bluetooth combo chip.
So describe both the 0.9V and the 3.3V regulators, then WCN7850 PMU and
the PCIe WLAN and the UART Bluetooth nodes.
This enables WLAN and Bluetooth functionality on the CRD.
