Thanks, but I don't see this particular patch in dt-for-4.1 you just pushed. ChenYu

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. The WiFi module supports out-of-band interrupt signaling via GPIO, but this is not supported in this patch.
