Bart, would it be still possible to take this into next? I would like to have at least this patch applied (with the first user) to allow conversion of others (I have some more users of new API).

Okay, seems we missed v6.7 with this, can you then prepare an immutable branch / tag with this, so other maintainers can pull in case it's needed? (I have something against tty already and perhaps something else, let's see.)

Sorry for the delay, immutable tag can be found at: git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core.git device_is_big_endian-6.8-rc1 for anyone to pull from now. thanks, greg k-h

No problem and thank you! Bart, can you pull that? Or should I to my tree and then push with other GPIO patches?

But v6.7-rc3 is something that is already in the upstream. I don't see how it can be more "mess" with this. Whatever... > Andy: How badly do you want it in v6.8? Can this wait until after the > merge window? I waited for a cycle already with this... OTOH GPIO part is not anyhow critical from the semantic point of view. Since the main patch is in Greg's tree I'll survive with GPIO stuff going next cycle.

What would make it a "mess"? It's all upstream already, taking a merge from a point further in time will work just fine, git is nice :) thanks, greg k-h

I did try it locally and noticed that a bunch of commits that were merged before rc3 moved "before it" in git log and figured this is what the PR would look like. However the PR is correct and I should have generated it before sending the email. Thanks for a lesson in git. Bartosz > thanks, > > greg k-h >

Some users want to use the struct device pointer to see if the device is big endian in terms of Open Firmware specifications, i.e. if it has a "big-endian" property, or if the kernel was compiled for BE *and* the device has a "native-endian" property.
