Subject: [PATCH v3 3/6] wifi: rtw88: 8723b: add the RTL8723B chip driver
Date: Mon, 21 Sep 2026 17:43:44 +0200 [thread overview]
Message-ID: <20260921154347.82317-4-luka.gejak@linux.dev> (raw)
In-Reply-To: <20260921154347.82317-1-luka.gejak@linux.dev>
Add the Realtek RTL8723B 802.11n chip driver: the chip operations, the
power sequences, the efuse layout, the RF and IQ calibration, and the
chip specific coexistence handling.
This depends on the shared core handling sent as a separate series,
"wifi: rtw88: preparations for RTL8723B/RTL8723BS". The driver is not
built yet; the Kconfig and Makefile entries follow.
The RTL8723B chip support is based on the initial work by
Michael Straube <straube.linux@gmail.com>.
