[PATCH v3] brcmfmac: support parse country code map from DT
With any regulatory domain requests coming from either user space or
802.11 IE (Information Element), the country is coded in ISO3166
standard. It needs to be translated to firmware country code and
revision with the mapping info in settings->country_codes table.
Support populate country_codes table by parsing the mapping from DT.
The BRCMF_BUSTYPE_SDIO bus_type check gets separated from general DT
validation, so that country code can be handled as general part rather
than SDIO bus specific one.

Changes for v3:
- Add missing terminating '\n' in brcmf_dbg(INFO, ...) format string.

[PATCH v2 1/2] dt-bindings: bcm4329-fmac: add optional brcm,ccode-map
Add optional brcm,ccode-map property to support translation from ISO3166 country code to brcmfmac firmware country code and revision. The country revision is needed because the RF parameters that provide regulatory compliance are tweaked per platform/customer. So depending on the RF path tight to the chip, certain country revision needs to be specified. As such they could be seen as device specific calibration data which is a good fit into device tree.

[PATCH v2 0/2] brcmfmac: support parse country code map from DT
This is a couple of patches adding optional brcm,ccode-map bindings for brcmfmac driver to parse country code map from DT. Changes for v2: - Rebase bindings patch on top of yaml conversion patch [1]. - Improve commit log with Arend's explanation on why this data could be put in device tree. - Use pattern to define mapping string as suggested by Rob. - Use brcmf_err() instead of dev_warn() and print error code. - Use sscanf() to validate mapping string. - Use brcmf_dbg(INFO, ...) to print country code entry. - Separate BRCMF_BUSTYPE_SDIO bus_type check from general DT validation.

I hope that the patch [1] from Rafał (copied) is one use case. And
also, the device I'm working on only needs to support some of the
countries in the mapping table.

I agree with you that such data are chipset specific and should ideally
be in the driver. However, the brcmfmac driver implementation has been
taking the mapping table from platform_data [2][3], which is a logical
equivalent of DT data in case of booting with device tree.

Thanks for the comment, Kalle. Actually, this is something I need some
input from driver maintainers. I can see this country code mapping
table is chipset specific, and can be hard coded in driver per chip id
and revision. But on the other hand, it makes some sense to have this
table in device tree, as the country code that need to be supported
could be a device specific configuration.

Yes. Will do, after driver maintainers agree with the direction.

Hmm, for some reason, kernel driver uses signed integer to hold the
revision. It's just a reflecting of that.

Ah, yes, that's much better and distinct. Thanks for the suggestion.

[PATCH 2/2] brcmfmac: support parse country code map from DT
With any regulatory domain requests coming from either user space or
802.11 IE (Information Element), the country is coded in ISO3166
standard. It needs to be translated to firmware country code and
revision with the mapping info in settings->country_codes table.
Support populate country_codes table by parsing the mapping from DT.

In this case, there is no point for kernel to continue efivars initialization. That said, efivar_init() should fail by returning an error code, so that efivarfs will not be mounted on /sys/firmware/efi/efivars at all. Otherwise, user space like efibootmgr will be confused by the EFIVARFS_MAGIC seen there, while EFI variable calls cannot be made successfully.

Just out of curiosity, this is a DIY cable or something generally

There are still some WiFi related devices. Can we drop all those

The new compatible needs to be documented. Also the compatible doesn't
look right, as this is a device from reMarkable rather than FSL.

[PATCH] cpufreq: qcom-hw: fix dereferencing freed memory 'data'
Commit 67fc209b527d ("cpufreq: qcom-hw: drop devm_xxx() calls from
init/exit hooks") introduces an issue of dereferencing freed memory
'data'. Fix it.
Fixes: 67fc209b527d ("cpufreq: qcom-hw: drop devm_xxx() calls from init/exit
hooks")
Reported-by: kernel test robot

Viresh,
The issue was introduced by v2 of "cpufreq: qcom-hw: drop devm_xxx()
calls from init/exit hooks", which misses the conversion of 'data->base'
in error path. Sorry!

So is it correct to say that clock is mandatory for !controlled-remotely BAM, while it's optional for controlled-remotely one. If yes, maybe we can do something like below to make the code a bit easier to read? if (controlled-remotely) bdev->bamclk = devm_clk_get_optional(); else bdev->bamclk = devm_clk_get(); > Yes, the probe code needs updating to handle -EPROBE_DEFER (esp if the clock > driver is built in as a module) I am not sure if the clock framework handles > -EPROBE_DEFER properly either.

As the patch breaks the assumption that for controlled-remotely BAM there is no clock to be managed, the probe code becomes buggy right away. Shawn

Shouldn't the following probe code need some update? Now we have both
controlled_remotely and clocks handle for cryptobam node. For example,
if devm_clk_get() returns -EPROBE_DEFER, we do not want to continue with
bamclk forcing to be NULL, right?
bdev->bamclk = devm_clk_get(bdev->dev, "bam_clk");
if (IS_ERR(bdev->bamclk)) {
if (!bdev->controlled_remotely)
return PTR_ERR(bdev->bamclk);
bdev->bamclk = NULL;
}

Ha, sorry, I did not check linux-next. I sent the message because
I see this fix is still missing after I rebase my Yoga C630 branch
to 5.11-rc4. We will get this fix into 5.11, right?
