Subject: [PATCH v5 12/12] ARM: dts: sun6i: hummingbird: Enable the onboard WiFi module
Date: Tue, 10 Mar 2015 19:59:24 +0800	[thread overview]
Message-ID: <1425988764-23618-14-git-send-email-wens@csie.org> (raw)
In-Reply-To: <1425988764-23618-1-git-send-email-wens@csie.org>

The Hummingbird A31 has an AMPAK AP6210 WiFi+Bluetooth module. The
WiFi part is a BCM43362 IC connected to MMC1 in the A31 SoC via SDIO.
The IC also takes a power enable signal via GPIO. This is supported
with the new power sequencing bindings.

The WiFi module supports out-of-band interrupt signaling via GPIO,
but this is buggy and not enabled yet.
