Subject: [PATCH 2/2] Bluetooth: btbcm: Add Synaptics 4384 chip support
Date: Mon, 17 Aug 2026 17:55:50 +0800 [thread overview]
Message-ID: <20260817095550.648774-3-kaihsin.chung@synaptics.com> (raw)
In-Reply-To: <20260817095550.648774-1-kaihsin.chung@synaptics.com>
Add support for the Synaptics 4384 Bluetooth controller
by adding the corresponding chip IDs.
Verify the change on the VIM3 platform.Verified
that the controller initializes successfully and
that firmware loading and basic Bluetooth operation
work as expected.
