[PATCH 2/4] Bluetooth: qca: add QCC2072 support
From: Yepuri Siddu
Date: Fri May 29 2026 - 14:16:54 EST
QCC2072 is a BT/WiFi combo SoC that uses different firmware
filenames and requires no external voltage regulators, so add
it as a new SoC type.
The chip supports the wideband speech and valid LE states
capabilities. Its firmware is named using the "orn" prefix and
follows the standard rom-version-based scheme:
- qca/ornbtfw<ver>.tlv
- qca/ornnv<ver>.bin
These firmware files are already present in the linux-firmware
repository.
