* Bluetooth Controller
|
||
|
|
Bluetooth controller communicates with the Bluetooth Host using HCI Transport layer.
|
||
|
|
HCI Transport layer can be based on UART or USB serial communication protocol.
|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
- compatible: Should be "qca,ar3002"
|
||
|
|
- qca,bt-reset-gpio: GPIO pin to bring BT Controller out of reset
|
||
|
|
- qca,bt-vdd-io-supply: Bluetooth VDD IO regulator handle
|
||
|
|
- qca,bt-vdd-pa-supply: Bluetooth VDD PA regulator handle
|
||
|
|
|
||
|
|
Optional properties:
|
||
|
|
-qca,bt-vdd-ldo-supply: Bluetooth VDD LDO regulator handle. Kept under optional parameters
|
||
|
|
as some of the chipsets doesn't require ldo or it may use from same vddio.
|
||
|
|
- qca,bt-chip-pwd-supply: Chip power down gpio is required when bluetooth module
|
||
|
|
and other modules like wifi co-exist in a singe chip and shares a
|
||
|
|
common gpio to bring chip out of reset.
|
||
|
|
- qca,bt-vdd-io-voltage-level: min and max voltages for the vdd io regulator
|
||
|
|
- qca,bt-vdd-pa-voltage-level: min and max voltages for the vdd pa regulator
|
||
|
|
- qca,bt-vdd-ldo-voltage-level: min and max voltages for the vdd ldo regulator
|
||
|
|
|
||
|
|
Example:
|
||
|
|
bt-ar3002 {
|
||
|
|
compatible = "qca,ar3002";
|
||
|
|
qca,bt-reset-gpio = <&pm8941_gpios 34 0>;
|
||
|
|
qca,bt-vdd-io-supply = <&pm8941_s3>;
|
||
|
|
qca,bt-vdd-pa-supply = <&pm8941_l19>;
|
||
|
|
qca,bt-chip-pwd-supply = <&ath_chip_pwd_l>;
|
||
|
|
qca,bt-vdd-io-supply = <1800000 1800000>;
|
||
|
|
qca,bt-vdd-pa-supply = <2900000 2900000>;
|
||
|
|
};
