[PATCH 0/4] wifi: ath9k: add ahb OF support

[Rosen Penev]

First two commits are small cleanups to make the changes of the third
simpler. The fourth actually adds dts definitions to use ahb.

[PATCH 1/4] wifi: ath9k: ahb: reorder declarations

[Rosen Penev]

Easier to look at. Follows netdev style.

Also remove ret assignment. Because of all of these devm conversions,
ret = 0 is a path that never gets hit. The first time it does it when
request_irq fails, but that ends up reassigning it.

Alphabetic includes are easier to look at and to make further changes to

[PATCH 3/4] wifi: ath9k: ahb: replace id_table with of

[Rosen Penev]

Since 2b0996c7646 , all of this platform code became no-op with no OF
replacement. Not only that, there are no users of AHB here. Add an OF
match table that mostly mirrors the original platform device id table.
Use a qca prefix as is done for the only other property: qca,no-eeprom.
Also used qca prefix for ar9530 as the latter seems to be a mistake.

This will be used to add ath9k support for the various ath79 devices
here.

Undocumented ABI.

Please run scripts/checkpatch.pl on the patches and fix reported
warnings. After that, run also 'scripts/checkpatch.pl --strict' on the
patches and (probably) fix more warnings. Some warnings can be ignored,
especially from --strict run, but the code here looks like it needs a
fix. Feel free to get in touch if the warning is not clear.

There is a wrapper for getting data, use it.

And dev_id is enum? Then you want kernel_ulong_t.

Hrm wonder where to document.

Documentation/devicetree/bindings/net/wireless/qca,ath9k.yaml

sounds like the place but that file looks like it's for pci(e) only.
This patch adds the bindings to ahb, not pci(e).

I assume you mean of_device_get_match_data. Will do.

The entries specified in data are macros in the form of 0xYYYY. This
is why I used u16. The ath9k_init_device takes an int here.

Interestingly enough in the newer ath drivers, it looks like these
macros are placed in an enum. ath9k uses a u16 field in the struct.

As for kernel_ulong_t, ath12k uses that, ath10k uintptr_t. I assume
the former is more appropriate.

You did not use u16, but uintptr_t. My comment was about the cast.

Now that OF ahb support was added to the ath9k driver, we can use it to

The name is enforced by bindings now (if you tested that). It's wifi.

It does not look like you tested the DTS against bindings. Please run
`make dtbs_check W=1` (see
Documentation/devicetree/bindings/writing-schema.rst or
https://www.linaro.org/blog/tips-and-tricks-for-validating-devicetree-sources-with-the-devicetree-schema/
for instructions).
Maybe you need to update your dtschema and yamllint. Don't rely on
distro packages for dtschema and be sure you are using the latest
released dtschema.

Please run scripts/checkpatch.pl on the patches and fix reported
warnings. After that, run also 'scripts/checkpatch.pl --strict' on the
patches and (probably) fix more warnings. Some warnings can be ignored,
especially from --strict run, but the code here looks like it needs a
fix. Feel free to get in touch if the warning is not clear.


Best regards,
Krzysztof
