[PATCH v2 0/2] arm64: dts: allwinner: Add Transpeed WiFi nodes

[PATCH v2 0/2] arm64: dts: allwinner: Add Transpeed WiFi nodes

[Andre Przywara]

Hi,

a tiny update, see below for the changelog.
======================================

This adds the WiFi DT nodes for the Transpeed 8K618T TV box. It uses a
Murata module with a Broadcom 4335 chip, which works fine with the
mainline Linux driver, given you provide the proper firmware files. We
found some in some LibreELEC repository.

Patch 1 adds the pinctrl node for the 32KHz clock fanout pin, patch 2
adds the actual SDIO WiFi node.

Please have a look!

Cheers,
Andre

Changelog v1 .. v2:
- add /omit-if-no-ref/ tag for clock fanout pin node
- update commit message to avoid mentioning Linux or driver

[PATCH v2 1/2] arm64: dts: allwinner: h616: Add 32K fanout pin

[Andre Przywara]

On some boards the designers saved on a 32KHz crystal for some external
chips, so the SoC has to help out, with providing a 32 KHz clock signal.

Add a pinctrl group node to allow DT nodes to reference this fanout signal.

[PATCH v2 2/2] arm64: dts: allwinner: Transpeed 8K618-T: add WiFi nodes

[Andre Przywara]

In contrast to other devices using Allwinner SoCs, the Transpeed 8K618-T
TV box uses a mainline supported WiFi chip: it's Broadcom 4335 compatible,
packaged by Murata.

Add the required DT nodes to let DT users know about the SDIO device.
There is an otherwise empty MMC device node, to receive the MAC address,
that firmware might want to write in there.

Ah, this is not sorted alphabetically. I can fix this while applying.
