Subject: [PATCH v2 8/8] rtw88: 8723d: initialize mac/bb/rf basic functions
Date:   Wed, 22 Apr 2020 11:46:07 +0800
Message-ID: <20200422034607.28747-9-yhchuang@realtek.com>

Sender: linux-wireless-owner@vger.kernel.org
Precedence: bulk

From: Ping-Ke Shih <pkshih@realtek.com>

Implement rtw_chip_ops::phy_set_param and ::mac_init to initialize
mac/bb/rf, and they are used during interface up. The procedure contains
power on sequence registers, download firmware, load predefined parameters,
mac/bb/rf specific register and etc.
