[PATCH 1/4] dt-bindings: bluetooth: qcom,qcc2072-bt: add bindings for QCC2072

[PATCH 1/4] dt-bindings: bluetooth: qcom,qcc2072-bt: add bindings for QCC2072

[Yepuri Siddu]

Document the YAML binding schema for the Qualcomm QCC2072 UART-based
Bluetooth controller.

Unlike other Qualcomm Bluetooth chips, QCC2072 requires no external
voltage regulators. The schema inherits common Qualcomm Bluetooth
properties via qcom,bluetooth-common.yaml and serial peripheral
interface properties for the UART link.

Where is the rest?

Also:
A nit, subject: drop second/last, redundant "bindings for". The
"dt-bindings" prefix is already stating that these are bindings.

Looks heavily incomplete. Devices do not work without power for example.

Also incomplete.

Thanks,  I will update this accordingly and send a v2 with the fixes.

The module receives power through the M.2 edge connector and manages its
own power sequencing internally. Unlike bare Qualcomm Bluetooth SoCs, it
requires no external voltage regulators, enable GPIOs, or clock supply
from the host, so no power-related properties are needed in the binding.

If this is a purely M.2 device, then it should not be a part of DT.

Exactly. And even PCI devices need power sequencing, unless this is a
simple (BT only) device.

QCC2072 is an M.2 E-key chip. As M.2 Power Sequencing changes are being 
upstreamed, we will reupdate our existing patches to align with M.2 
power sequencing approach.
This includes aligning the bindings, DT and also BT driver changes.
