The controller (product 0x20, ROM 0x0101, board ID 0x17) now loads ornbtfw11.tlv, ornnv11.bin and ornbcscal11.bin instead of falling back to ROM firmware, and a phone pairs and plays A2DP audio. With the mainline A16 DT (M.2 E connector, no Bluetooth node), patch 3 creates the BT node, but the card only powers on with Manivannan's "Bluetooth: hci_qca: Add M.2 Bluetooth device support using pwrseq" [1] applied too. Without it, hci_qca asks for a "bluetooth" pwrseq target the connector doesn't provide, W_DISABLE2# stays asserted and reading the version times out (-110). One of five boots failed: the rampatch download timed out ("command 0xfc00 tx timeout", "Failed to send TLV segment (-110)") and the "Retry BT power ON" never completed, leaving BT down until userspace powered it on. ath12k was bringing up WLAN on the same chip during the download in every boot, so I suspect contention there.
