[ Upstream commit 8059ba0bd0e4694e51c2ee6438a77b325f06c0d5 ]

On WCN3990 downloading the NVM sometimes fails with a "TLV response
size mismatch" error:

[  174.949955] Bluetooth: btqca.c:qca_download_firmware() hci0: QCA Downloading qca/crnv21.bin
[  174.958718] Bluetooth: btqca.c:qca_tlv_send_segment() hci0: QCA TLV response size mismatch

It seems the controller needs a short time after downloading the
firmware before it is ready for the NVM. A delay as short as 1 ms
seems sufficient, make it 10 ms just in case. No event is received
during the delay, hence we don't just silently drop an extra event.

Bluetooth: btqca: remove null checks on edl->data as it is an array 2016-09-19T18:19:34+00:00 Colin Ian King colin.king@canonical.com 2016-09-06T12:15:49+00:00 0676cab47ed18c9cfa884f055a3ba0f9e6fb8e96 edl->data is an array of __u8 so the null check is unneccessary, so remove it.

Bluetooth: btqca: Introduce generic QCA ROME support 2015-08-10T21:52:20+00:00 Ben Young Tae Kim ytkim@qca.qualcomm.com 2015-08-10T21:24:12+00:00 83e81961ff7ef75f97756f316caea5aa6bcc19cc This is for supporting BT for QCA ROME with vendor specific HCI commands and initialization on the chip. This will have USB/UART implementation both, but for now, adding UART vendor specific commands to patch downloading and set Bluetooth device address using vendor specific command.
