From mboxrd@z Thu Jan 1 00:00:00 1970 From: hdegoede@redhat.com (Hans de Goede) Date: Fri, 2 May 2014 17:57:29 +0200 Subject: [PATCH v10 15/15] ARM: dts: sun7i: Add basic support for the Cubietruck WiFi module In-Reply-To: <1399046249-19472-1-git-send-email-hdegoede@redhat.com> References: <1399046249-19472-1-git-send-email-hdegoede@redhat.com> Message-ID: <1399046249-19472-16-git-send-email-hdegoede@redhat.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org From: Chen-Yu Tsai The CubieTruck has an AMPAK AP6210 WiFi+Bluetooth module. The WiFi part is a BCM43362 IC connected to MMC3 in the A20 SoC via SDIO. The IC also takes a power enable signal via GPIO. The WiFi module supports out-of-band interrupt signaling via GPIO, but this is not supported in this patch.
