--------------------- |
|
|
|
This documents the binding structure and common properties for serial |
|
attached Qualcomm devices. |
|
|
|
Serial attached Qualcomm devices shall be a child node of the host UART |
|
device the slave device is attached to. |
|
|
|
Required properties: |
|
- compatible: should contain one of the following: |
|
* "qcom,qca6174-bt" |
|
* "qcom,qca9377-bt" |
|
* "qcom,wcn3990-bt" |
|
* "qcom,wcn3991-bt" |
