[RFC] rfkill: Add new ACPI device for Realtek serial BT

[RFC] rfkill: Add new ACPI device for Realtek serial BT

[Larry Finger]

The Realtek RTL8723BS chips, which are connected via SDIO, also contain
a serial Bluetooth device. In order for BT to work, the device must be
added to the acpi_device_id table.

I have no idea if this device should be added here, or if the device could
be added to some structure supplied at device startup. If anyone has any
suggestions, please let me know.

Thanks,

Larry

it should not be added here. Since most likely more is needed. For example within the hci_bcm.c and hci_intel.c drivers we handle the GPIO when attaching the UART to the Bluetooth subsystem. This means at minimum some sort of hci_rtl.c is needed. Can be for the beginning just an enhanced hci_h4.c.

Marcel

BTW Johannes maintains rfkill, not me.
