Bluetooth: btusb: Remove WAKEUP_DISABLE and add WAKEUP_AUTOSUSPEND for Realtek devices

2021-08-19T15:08:31Z

For the commit of 9e45524a011107a73bc2cdde8370c61e82e93a4d, wakeup is always disabled for Realtek devices. However, there's the capability for Realtek devices to apply USB wakeup. In this commit, remove WAKEUP_DISABLE feature for Realtek devices. If users would switch wakeup, they should access "/sys/bus/usb/.../power/wakeup" In this commit, it also adds the feature as WAKEUP_AUTOSUSPEND for Realtek devices because it should set do_remote_wakeup on autosuspend.

Bluetooth: btusb: check conditions before enabling USB ALT 3 for WBS

2021-08-10T18:28:49Z

Some USB BT adapters don't satisfy the MTU requirement mentioned in commit e848dbd364ac ("Bluetooth: btusb: Add support USB ALT 3 for WBS") and have ALT 3 setting that produces no/garbled audio. Some adapters with larger MTU were also reported to have problems with ALT 3. Add a flag and check it and MTU before selecting ALT 3, falling back to ALT 1. Enable the flag for Realtek, restoring the previous behavior for non-Realtek devices. Tested with USB adapters (mtu<72, no/garbled sound with ALT3, ALT1 works) BCM20702A1 0b05:17cb, CSR8510A10 0a12:0001, and (mtu>=72, ALT3 works) RTL8761BU 0bda:8771, Intel AX200 8087:0029 (after disabling ALT6). Also got reports for (mtu>=72, ALT 3 reported to produce bad audio) Intel 8087:0a2b.

Bluetooth: btintel: Fix the legacy bootloader returns tlv based version

2021-08-05T14:03:30Z

From the ThP, it supports both legacy and TLV based HCI_Intel_Read_Version command after downloading the operational firmware, and it causes the driver to choose the wrong setup routines and missing firmware/ddc file. So, as a workaround, this patch checks the fw variant from the TLV based version, and if the device is legacy bootloader device, the legacy HCI_Intel_Read_Version command is used to get the legacy version information and run the legacy bootloader setup with it.
