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

[Andre Przywara]

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 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

[PATCH 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 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 a Broadcom 4335
compatible, packaged by a company called Murata.
It works nicely with the Linux driver, when providing the respective
firmware files.

Add the required DT nodes to let the kernel find the SDIO device.

Can you reword message in a way to omit Linux?

I don't think this node and alias are useful in any way. SDIO scan will find
device regardless and potential mac property set up by bootloader will be
ignored anyway.

Probably reword it to say "add nodes so that custom MAC addresses can be
associated with it"?

If a node with the matching function number is found, the MMC core will
associate the node with the SDIO function device before calling the probe
function. It has worked correctly for quite some time.

If the driver isn't taking the MAC address given in the DT, then that's
a driver issue.

Ah, I didn't know. Ok then, Andre, just update commit message and it's good
to go.
