Subject: [PATCH v2 8/8] rtw88: 8723d: Add read_efuse to recognize efuse info from map
Date: Mon, 20 Apr 2020 13:50:54 +0800	[thread overview]
Message-ID: <20200420055054.14592-9-yhchuang@realtek.com> (raw)
In-Reply-To: <20200420055054.14592-1-yhchuang@realtek.com>

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

The logical efuse map is decoded from physical map by parsing the
header format of the physical map. And each different type of chips
has different logical efuse layout. So add the logical map's layout
for parsing the efuse contents.
