[PATCH 0/7] [DTS] enable hardware for Nanopi M1 & Nanopi M1 Plus

[Philipp Rossak]

From: Philipp Rossak <embed3d@gmail.com>

This Patchseries enables the IR controller and the dwmac-sun8i
on the Friendlyarm Nanopi M1 and Friendlyarm Nanopi M1 Plus boards.
On the Nanopi M1 Plus additionally the BT/Wifi module is activated.

[PATCH 4/7] ARM: dts: sun8i: h3: Enable AP6212 WiFi on mmc1 on Nanopi M1 Plus

[Philipp Rossak]

From: Philipp Rossak <embed3d@gmail.com>

The WiFi side of the AP6212 WiFi/BT combo module is connected to
mmc1. There are also GPIOs for enable and interrupts.

Enable WiFi on this board by enabling mmc1 and adding the power
sequencing clocks and GPIO, as well as the chip's interrupt line.

There's no need for pinctrl nodes when the pin is set to a GPIO.

You don't need vqmmc in this case.

[PATCH 4/7] ARM: dts: sun8i: h3: Enable AP6212 WiFi on mmc1 on Nanopi M1 Plus

[Philipp Rossak]

Hi,
thanks for the feedback I will rework the patch.
Should I also update the sun8i-h3-bananapi-m2-plus.dts? It uses also the 
AP6212 and it is done in the same way like in this patch.
