Subject: [PATCH 07/20] ARM: dts: imx6qdl-gw5910: add support for bcm4330-bt
|
|
|
|
The Sterling-LWB has a BCM4330 which has a UART based bluetooth
|
|
HCI. Add support for binding to the bcm_hci driver to take care
|
|
of handling the shutdown gpio and loading firmware.
|
|
|
|
Because the shutdown gpio is more of an enable than a regulator
|
|
go ahead and replace the regulator with a shutdown-gpio.
