Subject: [PATCH 5/6] btbcm: disable read tx power for iMac 20,1 (Retina 5K, 27-inch, 2020)
Date: Mon, 29 Nov 2021 07:31:32 +0000	[thread overview]
Message-ID: <E9DE81E7-F408-414F-AB25-D71657E5177A@live.com> (raw)
In-Reply-To: <3E9D8424-A65C-4211-B5E4-B6D62400E711@live.com>

From: Aditya Garg <gargaditya08@live.com>

Bluetooth on Apple iMac 20,1 is unable to start due to LE Min/Max Tx Power being queried on startup. Add a DMI based quirk so that it is disabled.
