* 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 set to one of the following:
|
|
qca,ar3002
|
|
qca,qca6174
|
|
qca,wcn3990
|
|
qca,qca6390
|
|
qca,wcn6750
|
|
- qca,bt-reset-gpio: GPIO pin to bring BT Controller out of reset
|
|
- qca,wl-reset-gpio: GPIO pin for WLAN EN, used here to check status only
|
|
|
|
Optional properties:
|
|
- qca,bt-vdd-pa-supply: Bluetooth VDD PA regulator handle
|
|
- qca,bt-vdd-io-supply: Bluetooth VDD IO regulator handle
|
|
- 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-vdd-xtal-supply: Bluetooth VDD XTAL regulator handle
|
|
- qca,bt-vdd-core-supply: Bluetooth VDD CORE regulator handle
|
|
- qca,bt-vdd-asd-supply: Bluetooth VDD regulator handle for antenna switch
|
|
diversity.
|
|
- 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-pa-voltage-level: specifies VDD PA voltage levels for supply.
|
|
Should be specified in pairs (min, max), units uV
|
|
- qca,bt-vdd-io-voltage-level: specifies VDD IO voltage levels for supply.
|
|
Should be specified in pairs (min, max), units uV
|
|
- qca,bt-vdd-ldo-voltage-level: specifies VDD LDO voltage levels for supply.
|
|
Should be specified in pairs (min, max), units uV
|
|
- qca,bt-vdd-xtal-voltage-level: specifies VDD XTAL voltage levels for supply.
|
|
Should be specified in pairs (min, max), units uV
|
|
- qca,bt-vdd-core-voltage-level: specifies VDD CORE voltage levels for supply.
|
|
- qca,bt-vdd-asd-voltage-level: specifies VDD voltage levels for supply for
|
|
antenna switch diversity. Should be specified in pairs (min, max), units uV
|
|
- qca,bt-vdd-io-current-level: specifies VDD IO current level in microamps
|
|
- qca,bt-vdd-xtal-current-level: specifies VDD XTAL current level in microamps
|
|
- qca,bt-vdd-core-current-level: specifies VDD CORE current level in microamps.
|
|
- qca,bt-vdd-ldo-current-level: specifies VDD LDO current level in microamps.
|
|
- qca,bt-vdd-pa-current-level: specifies VDD PA current level in microamps.
|
|
- qca,bt-chip-pwd-current-level: specifies Chip Power current level in microamps.
|
|
- qca,bt-vdd-asd-current-level: specifies VDD ASD current level
|
|
|
