As discussed previously, these two ARM platforms have no
known remaining users, let's remove them completely.
Subsystem maintainers: feel free to take the driver removals
through your respective trees, they are all independent of
one another. We can merge any remaining patches through the
soc tree.

As discussed previously, these two ARM platforms have no
known remaining users, let's remove them completely.
Subsystem maintainers: feel free to take the driver removals
through your respective trees, they are all independent of
one another. We can merge any remaining patches through the

As discussed previously, these two ARM platforms have no
known remaining users, let's remove them completely.
Subsystem maintainers: feel free to take the driver removals
through your respective trees, they are all independent of
one another. We can merge any remaining patches through the
soc tree.

ks8695 is an older SoC originally made by Kendin, which was later acquired
by Micrel, and subsequently by Microchip.
The platform port was originally contributed by Andrew Victor and Ben
Dooks, and later maintained by Greg Ungerer.
When I recently submitted cleanups, but Greg noted that the platform no
longer boots and nobody is using it any more, we decided to remove it.

instruction and data caches. It is used in Altera's

ks8695 is an older SoC originally made by Kendin, which was later acquired
by Micrel, and subsequently by Microchip.
The platform port was originally contributed by Andrew Victor and Ben
Dooks, and later maintained by Greg Ungerer.
When I recently submitted cleanups, but Greg noted that the platform no
longer boots and nobody is using it any more, we decided to remove it.

The ARM922T is a version of the ARM920T, but with smaller
instruction and data caches. It is used in Altera's
- Excalibur XA device family and Micrel's KS8695 Centaur.
+ Excalibur XA device family and the ARM Integrator.
Say Y if you want support for the ARM922T processor.
Otherwise, say N.

I'm not going to object to this.

Really, this address should only be used for /work/ stuff.

The patch
ASoC: remove w90x900/nuc900 platform drivers
has been applied to the asoc tree at
https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-5.4
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

Subject: [PATCH] ASoC: remove w90x900/nuc900 platform drivers
The ARM w90x900 platform is getting removed, so this driver is obsolete.

The patch
ASoC: remove w90x900/nuc900 platform drivers
has been applied to the asoc tree at
https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-5.4
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

Subject: [PATCH] ASoC: remove w90x900/nuc900 platform drivers
The ARM w90x900 platform is getting removed, so this driver is obsolete.

To: soc
Cc: Arnd Bergmann, Bartlomiej Zolnierkiewicz, linux-kernel,
dri-devel, linux-fbdev
The ARM w90x900 platform is getting removed, so this driver is obsolete.

BTW there is a very minor issue with internal bisectability of
this patch series (non-issue in reality because it affects only
configs with ARCH_W90X900=y and such are now gone, just FYI):
arch/arm/mach-w90x900/dev.c (which stays in tree until patch #16
("ARM: remove w90x900 platform") uses include/linux/platform_data/
files removed in patches #7 (spi), #9 (fbdev) and #10 (keyboard).

Ah right, I actually planned to change that originally but forgot.
As you say, it's not a huge issue except for building randconfig or
nuc900_defconfig.

This removes the old Winbond w90x900 platform, also known
as Nuvoton NUC900. Wan Zongshun originally contributed
the port and maintained it since then.
From all I can tell, this platform is no longer being used
with modern kernels, based on various indications:
- The supported chips (nuc910/950/960) are no longer marketed
by the manufacturer
- Newer chips from the same family (nuc97x, nuc980, n329x)
that are still marketed have Linux BSPs but those were never
submitted for upstream inclusion.
- The last patch from the platform maintainer was in 2011.
- All patches to w90x900 platform specific files afterwards
are cleanups that were apparently done without access to
test hardware.
- Both the website and the email address listed in the
MAINTAINERS have become unreachable.

This removes the old Winbond w90x900 platform, also known
as Nuvoton NUC900. Wan Zongshun originally contributed
the port and maintained it since then.
From all I can tell, this platform is no longer being used
with modern kernels, based on various indications:
- The supported chips (nuc910/950/960) are no longer marketed
by the manufacturer
- Newer chips from the same family (nuc97x, nuc980, n329x)
that are still marketed have Linux BSPs but those were never
submitted for upstream inclusion.
- The last patch from the platform maintainer was in 2011.
- All patches to w90x900 platform specific files afterwards
are cleanups that were apparently done without access to
test hardware.
- Both the website and the email address listed in the
MAINTAINERS have become unreachable.
