[PATCH v2 0/2] [DTS] Enable hardware for Nanopi M1 & Nanopi M1 Plus

[PATCH v2 0/2] [DTS] Enable hardware for Nanopi M1 & Nanopi M1 Plus

[Philipp Rossak]

From: Philipp Rossak <embed3d@gmail.com>

This is v2 of my Enable hardware for Nanopi M1 & Nanopi M1 Plus Patchseries.

Changes since v1:

  - removed pincrtl node from power sequence

  - removed vqmmc-supply

  - changed ap6212 label to sdio_wifi

  - removed vqmmc-supply & pincrtl node for powersequence on Bananapi M2 Plus

  - Droped patches for the IR controller & UART that are allready queued for 4.15

  - Droped dwmac-sun8i patches

Original cover letter from v1:

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 v2 1/2] ARM: dts: sun8i: h3: Enable AP6212 WiFi on mmc1 on Nanopi M1 Plus

[Philipp Rossak]

From: Philipp Rossak <embed3d-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>

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.

When the Wi-Fi module itself has fixed MAC address, there's
no need for such an alias.

I know I told you you weren't needing vqmmc, but Chen-Yu later told me
that I was wrong about this.

I've added vqmmc back, and applied your patch.

Thanks!

But the description is also accurate, which is what matters in the DT.

So we actually need this one.

And there's also other GPIO pins here, I'd prefer if you could tackle
them all at once.
