Subject: [PATCH v4 3/6] Bluetooth: qca: add WCN3950 support
Date: Fri, 07 Feb 2025 22:41:17 +0200	[thread overview]
Message-ID: <20250207-rb1-bt-v4-3-d810fc8c94a9@linaro.org> (raw)
In-Reply-To: <20250207-rb1-bt-v4-0-d810fc8c94a9@linaro.org>

WCN3950 is another example of the WCN39xx BT/WiFI family of chips. It
requires different firmware files and has different current
requirements, so add it as a separate SoC type.

The firmware for these chips has been recently added to the
linux-firmware repository and will be a part of the upcoming release:
- qca/cmbtfw12.tlv
- qca/cmbtfw13.tlv
- qca/cmnv12.bin
- qca/cmnv13.bin
- qca/cmnv13s.bin
- qca/cmnv13t.bin
