[PATCH v2 0/5] Add AP6275P wireless support

[Jacobe Zang]

These add AP6275P wireless support on Khadas Edge2. Enable 32k clock 
for Wi-Fi module and extend the hardware IDs table in the brcmfmac 
driver for it to attach.

Changes in v2:
 - Add SoB tags for original developer.
 - Add dt-bindings for pci14e4,449d and clocks.
 - Replace dev_info to brcmf_dbg in pcie.c

 - Link to v1: https://lore.kernel.org/all/20240620020015.4021696-1-jacobe.zang@wesion.com/

Isn't bus-range a property of PCI host bridge, so the parent? This is a
PCI device, right?

Binding does not say anything about this. Rockchip PCI controller is the
PCI host bridge, isn't it? Then the pci@0,0 is the child, so what is this?

1. Bindings are before the users.
2. Where is the compatible? Are you sure this validates?

The host bridge is the parent of pcie@0,0. And pcie@0,0 is Bridge1, so the
wifi@0,0 as a device under the Bridge1.

Before, the compatible is "pci14e4,449d", but when I checkpatch the warning
said that "pci14e4" was not documented, so I remove the compatible which 
doesn't affect the Wi-Fi function. I have tried to add "pci14e4" to 
vendor-prefixes.yaml but was refused. So whether should I add the compatible 
with warning?

Do you want to say Rockchip PCI is PCI-PCI bridge? Bindings do not allow it.

I talk about dtbs_check, not checkpatch. That checkpatch warning does
not matter, obviously.

[PATCH v2 2/5] net: wireless: brcmfmac: Add optional 32k clock enable support

While it is a 32kHz clock I would prefer to use the functional name. The 
input pin on the chip is called "LPO_IN" in our schematics as well as in 
the AMPAK datasheet. In the Edge 2 schematics it is simply "LPO". 
Another name used is "EXT_LPO" as opposed to the internal LPO, which can 
be selected through boardflags3 in nvram file. Having the clock external 
is better although it seems the edge 2 does not provide the recommended 
ppm. In short I would suggest to pick one of the following names: 
lpo-in, lpo, or ext-lpo.

This affect the driver patch which is why I tend to go for consensus on 
the bindings first before posting a driver patch. With only a single 
rename it is not that much churn though.

Regards,
Arend

Sure. LPO is more common for the clock name. I will rename it.

Which devices have this clock? All? You now mention driver, but this is
a binding so please describe hardware.

Subject: drop full stops. In every patch.
