[PATCH v2 00/33] spi: get rid of some legacy macros

Hello,

this is v2 of this patch set.

Changes since (implicit) v1, sent with Message-Id:
cover.1705348269.git.u.kleine-koenig@pengutronix.de:

 - Rebase to v6.8-rc1
 - Fix a build failure on sh
 - Added the tags received in (implicit) v1.

The slave-mt27xx driver needs some more work. The patch presented here
is enough however to get rid of the defines handled in patch 32.
Cleaning that up is out-of-scope for this series, so I'll delay that
until later.

Note that Jonathan Cameron has already applied patch 3 to his tree, it
didn't appear in a public tree though yet. I still included it here to
make the kernel build bots happy.

Best regards
Uwe

In commit 8caab75fd2c2 ("spi: Generalize SPI "master" to "controller"")
some functions and struct members were renamed. To not break all drivers
compatibility macros were provided.

To be able to remove these compatibility macros push the renaming into
this driver.

Ah.  I thought intent was to split this across all the different trees
then do the final patch only after they were all gone?

I'm fine with it going all in one go if people prefer that.

My tree will be out in a few mins. Was just waiting to rebase on rc1
which I've just done.

Are we supposed to take the individual changes in our different
subsystem trees, or do you want them all to go through the spi tree?

Either is fine with me, just need to know.

Given that the final patch removes the legacy interfaces I'm expecting
to take them via SPI.

Great, thanks, I'll go ack the subsystem patches that are relevent for
me.

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark
