In my quick check, The driver which is supporting "ak" is only ak8975. Other Asahi-Kasei driver is using "asahi-kasei".
Very interesting is that the document of ak8975 ./Documentation/devicetree/bindings/iio/magnetometer/ak8975.txt said it should be "asahi-kasei"
what is the policy of Documentation/devicetree/bindings/vendor-prefixes.txt ?

They're usually referred to as AKM when abbreviated and their web site is http://www.akm.com/ - don't know what the stock ticker symbol is. In any case there's no real cost to adding both abbreviated and non-abbreviated forms if we want to transition.

Sounds like akm, is a better bet then, especially as ak, has no real adoption.

Sorry to jump in on this late, but what on earth is wrong with "ak". It went through the appropriate review process, and is already in use. Admittedly only in a single ARM DT file, but it's still in use. We'll have to allow the ak prefix forever given that DT is an ABI, so rather than introducing more random variations, we should just stick with what we have.

Well, the issue is that in reality the bulk of the drivers are using asahi-kasei, we're going to have to churn at least something anyway. We seem to have one in tree user of ak in a DTS file and two DTSs using asahi-kasei with seven drivers.

As far as DTs go, there are only 2 users of asahi-kasei, and they were both added well after the prefix was documented, so those seem like plain old bugs.
But due to ABIness, perhaps we have to support both ak and asahi-kasei. I don't think fixing this implies we should introduce a third option akm though. No DT is using that today.

I'm fine with this patch, but just wanted to comment on this part of the commit description:
What is in the drivers isn't relevant; that's not what drives the ABI. The issue is that some *DTs* use ak and some use asahi-kasei, so both those need to be supported.
That said, we should document which one of the two prefixes is preferred, and use this for any new AK binding.
It would also be nice to ensure the preferred prefix is in all drivers' of_match_tables, and remove the deprecated prefix from all drivers' of_match_tables *except* where there's already a DT file that references the deprecated vendor prefix.

If we're adding a new string, we should figure out what's happening with the old one. We want some consistency here.
From a quick grep, it looks like the only use of "ak" is "ak,ak8975" in
arch/arm/boot/dts/tegra20-seaboard.dts. There are instances of "asahi-kasei,ak8975" in other dts files.
Olof added "asahi-kasei,ak8975" to the ak8975 driver in February 2012 (see 54461c3067b2), and the "asahi-kasei" prefix is currently far more common. This was only documented in May 2013 (see f4b7f751c6fd).
Stephen added the "ak" vendor-refix was added later in November 2012 (see ae8c4209af2c), and the only instance seems to work due to the i2c subsystem doing something dehind the scenes with the compatible string. So I think we made a mistake there.
Given all that, I think we should get rid of the "ak" prefix entirely, fix up the seaboard dts, and leave the legacy matching for "ak,ak8975" up to the i2c framework. However, that would imply deleting from vendor-prefixes.txt (if we want people to be warned on use of "ak"), and that's not a good precedent to set.
Thoughts?
Mark.

Ah. I tried to see if we had any deprecated bindings, but I somehow failed to search correctly and missed powervr.

I guess removing "ak" line from vendor-prefixes.txt is very enough for warn for a deprecated vendor prefix on checkpatch ?

Hi Joe,
I think that what Morimoto-san wanted to say was something like this:
I guess that removing the "ak" line from vendor-prefixes.txt would be sufficient to cause checkpatch to generate a warning about using the deprecated "ak" vendor prefix. Is that a good approach?

I think that what Morimoto-san wanted to say was something like this:
I guess that removing the "ak" line from vendor-prefixes.txt would be sufficient to cause checkpatch to generate a warning about using the deprecated "ak" vendor prefix. Is that a good approach?
Yes, this is. Thank you Simon, Sorry Joe.

It'd be a bit nicer to be able to leave it there with a note saying it was legacy (if only so people don't try to add it back) but I don't mind too much.

Current vendor-prefixes.txt already has "ak" prefix for Asahi Kasei Corp by ae8c4209af2cec065fef15d200a42a04130799f7 (of: Add vendor prefix for Asahi Kasei Corp.)
It went through the appropriate review process. But, almost all Asahi Kasei chip drivers are using "asahi-kasei" prefix today. (arch/arm/boot/dts/tegra20-seaboard.dts only is using "ak,ak8975", but there are instances of "asahi-kasei,ak8975" in other dts files. And drivers/iio/magnetometer/ak8975.c doesn't support "ak,ak8975") So, we made a mistake there.
In addition, checkpatch.pl reports WARNING if it is using "asahi-kasei" prerfix in DT file. (DT compatible string vendor "asahi-kasei" appears un-documented)
Marking it deprecated and warning with checkpatch is certainly preferable. So, this patch replace "ak" to "asahi-kasei" in vendor-prefixes.txt. (and fixup tegra20-seaboard)
OTOH, Asahi Kasei is usually referred to as "AKM", but this patch doesn't care about it. Because no DT is using that today.

No, the i2c bus behaves in a special way by matching the "ak8975" i2c driver name with any "*,ak8975" DT compatible string. Both of the above will work with existing kernels.

I2C (like SPI) has a fallback in case the OF table yields no match. The of_modalias_node() that it uses extracts the module name from the device tree node's compatible string by skipping the vendor prefix. The resulting string is then set as the I2C client's name and causes the I2C standard ID matching to succeed (see of_i2c_register_devices() for how this is done in detail).
I cannot find "ak,ak8975" anywhere else in the kernel.

Technically this is breaking backwards-compatibility from a DT perspective, but I think it's safe to do because the Linux kernel has a way of dealing with this and other operating systems should be able to deal with this in a similar way (or even easier by letting the driver match on the ak prefix as well for this particular chip).
So:

It's usually enough to show the first 12 (or so) characters of the SHA1 here. git will show you the right one if you do something like:
git log --abbrev=12 --abbrev-commit
It's probably useful to "git config core.abbrev 12" for Linux kernel repositories.
Other than that it seems like you're being overly careful about not exceeding 72 characters. Your lines seem to wrap at around less than 50 columns. However, making lines too short results in equally hard to read commit messages, so please try to shoot for 72 columns for maximum readability.

Current vendor-prefixes.txt already has "ak" prefix for Asahi Kasei Corp by ae8c4209af2c(of: Add vendor prefix for Asahi Kasei Corp.)
It went through the appropriate review process. But, almost all Asahi Kasei chip drivers are using "asahi-kasei" prefix today. (arch/arm/boot/dts/tegra20-seaboard.dts only is using "ak,ak8975", but there are instances of "asahi-kasei,ak8975" in other dts files. And drivers/iio/magnetometer/ak8975.c doesn't support "ak,ak8975" prefix) So, we made a mistake there.
In addition, checkpatch.pl reports WARNING if it is using "asahi-kasei" prerfix in DT file. (DT compatible string vendor "asahi-kasei" appears un-documented)
Marking it deprecated and warning with checkpatch is certainly preferable. So, this patch replace "ak" to "asahi-kasei" in vendor-prefixes.txt. (and fixup tegra20-seaboard)

It doesn't seem to be ack'd by any of the DT maintainers. Retro-actively changing a DT vendor name would need that, I think.
Thierry and Alex (both Tegra maintainers) appear to have ack'd it, so it seems they expect it to go through some tree other than Tegra. Weren't there a bunch of related patches along with this (e.g. updating relevant drivers to support both prefixes?) so it was expected this patch would be applied together with them?

It's an i2c device, so it won't break, based on the implementation we use in the kernel that ignores the vendor part when the part number matches the i2c driver name.
I also don't think we need to worry about any non-Linux operating systems on this board that might share the same dts file.

Plus this update is actually changing the board DT file have the ID which we've always had in the driver, the driver has always used the new string and never the ak, based one that the device tree is registering.

As far as DTs go, there are only 2 users of asahi-kasei, and they were both added well after the prefix was documented, so those seem like plain old bugs.
But due to ABIness, perhaps we have to support both ak and asahi-kasei. I don't think fixing this implies we should introduce a third option akm though. No DT is using that today.
