Subject: [PATCH v2 07/11] rtw88: coex: Change antenna setting to enhance free-run performance
Date: Thu, 12 Nov 2020 11:14:26 +0800	[thread overview]
Message-ID: <20201112031430.4846-8-pkshih@realtek.com> (raw)
In-Reply-To: <20201112031430.4846-1-pkshih@realtek.com>

From: Ching-Te Ku <ku920601@realtek.com>

While the mechanism goes to 2G_free_run or WL5G_BT2G,
set BT to hardware PTA mode to get a more efficiently performance.

Add a flag to indicate antenna switch is supported or not so
that the IC serials which has different antenna structure can
set antenna correctly.
