Subject: [PATCH v9] Bluetooth: btbcm: Add Synaptics 4384 chip support
Date: Wed,  1 Jul 2026 16:01:38 +0800	[thread overview]
Message-ID: <20260701080138.3786003-1-kaihsin.chung@synaptics.com> (raw)
In-Reply-To: <20260624081947.2495351-1-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

Changes in v9:
- Align bcm_uart_subver_table formatting.
- Group the Broadcom DT compatible entries together.
- Capitalize the author's given name.
