From mboxrd@z Thu Jan 1 00:00:00 1970 From: Chen-Yu Tsai Subject: [PATCH 3/3] ARM: dts: sun9i: cubieboard4: Enable AP6330 WiFi Date: Fri, 28 Oct 2016 18:11:54 +0800 Message-ID: <20161028101154.7350-4-wens@csie.org> References: <20161028101154.7350-1-wens@csie.org> Return-path: In-Reply-To: <20161028101154.7350-1-wens@csie.org> Sender: linux-kernel-owner@vger.kernel.org To: Maxime Ripard Cc: Chen-Yu Tsai , devicetree@vger.kernel.org, linux-arm-kernel@lists.infradead.org, linux-kernel@vger.kernel.org List-Id: devicetree@vger.kernel.org The board has a Ampak AP6330 WiFi/BT/FM module. Inside it is a Broadcom BCM4330 WiFi/BT/FM combo IC. The WiFi portion is connected to mmc1, with the enabling pin connected to PL2. The AC100 RTC provides a low power clock signal.
