Bluetooth: Make BT_HCIUART_RTL configuration option depend on ACPI

2018-08-21T14:36:12+00:00

At the moment we only support ACPI enumeration for serial port attached
RTL bluetooth controllers.

This commit adds a dependency on ACPI to the BT_HCIUART_RTL configuration
option, fixing the following warning when ACPI is not enabled:

drivers/bluetooth/hci_h5.c:920:22: warning: 'rtl_vnd' defined but not used

Bluetooth: mediatek: pass correct size to h4_recv_buf()

2018-08-13T13:59:39+00:00

We're supposed to pass the number of elements in the mtk_recv_pkts, not
the number of bytes.

Bluetooth: btqca: Introduce HCI_EV_VENDOR and use it

2018-08-06T18:25:05+00:00

Using HCI_VENDOR_PKT for vendor specific events does work since it has
also the value 0xff, but it is actually the packet type indicator
constant and not the event constant. So introduce HCI_EV_VENDOR and
use it.

Bluetooth: h5: Fix missing dependency on BT_HCIUART_SERDEV

2018-08-04T21:23:32+00:00

This driver was recently updated to use serdev, so add the appropriate
dependency. Without this one can get compiler warnings like this if
CONFIG_SERIAL_DEV_BUS is not enabled:

  CC [M]  drivers/bluetooth/hci_h5.o
