[PATCH 00/22] ARM: clps711x: Switch to DT and Multiplatform

[PATCH 00/22] ARM: clps711x: Switch to DT and Multiplatform

[Alexander Shiyan]

The Cirrus Logic company announced EOL on May 20 this year for the
ARMv4 processors, so the company where I work ceases the use of the CPU
for our devices and switches our boards to use with another type of CPU.
I can not continue develop for this platform, so I gathered all the
existing patches/solutions for the final series. Of course, we keep
support our existing products with this CPU, so I remain able to check
any third-party patches.
This series of patches switches CLPS711X platform for use with device
tree and adds multiplatform support.
The series contain various subsystem changes but designed for applying
directly in the ARM-SOC tree.

[PATCH 01/22] ARM: clps711x: Reduce static map size

[Alexander Shiyan]

Last CLPS711X CPU register is PLLR has 0xa5a8 address, so we can reduce
the map to 48k and align the end of the static at VMALLOC_START.

[PATCH 07/22] gpio: clps711x: Changing the compatibility string to match with the smallest supported chip

[Alexander Shiyan]

This patch changes the compatibility string to match with the smallest
supported chip (EP7209). Since the DT-support for this CPU is not yet
announced, this change is safe.

[PATCH 22/22] ARM: config: Add a multi_v4t_defconfig

[Alexander Shiyan]

To allow regression build testing of multi v4t systems, add a
multi_v4t_defconfig, similar to the multi_v5(v7)_defconfig.

This adds a new binding but no binding document - all new bindings need
binding documents.  Other than that it looks fine.

BTW I hope it's OK to take these three patches and apply
separately, else tell me and I'll take them out again and you
can have my Acked-by if you want to take them through ARM
SoC instead.

I think that's fine. We will have a short time span during the
merge window in which not everything works with either DT or
the board files, but as Alexander explained, this hardware
is now obsolete, so I think that is ok in this instance,
and it makes the migration easier.

I've written a binding file for that now, and submitted that along
with this patch. Please either pick up both patches into your spi
tree or provide an Ack so I can put them into a branch for arm-soc
along with the other patches.

Linus Walleij has already applied some other patches out of sequence,
so we won't be able to bisect clps711x across the DT conversion, but
I think that's ok now, as the platform is really dead as Alexander
described.

I've applied the majority of these into arm-soc now. I did not
care much about ordering for bisection except for build coverage,
as we already broke bisection when the gpio changes got applied.

I'm sure nobody cares about it too much.

I've sent this to Mark Brown along with the missing binding description.
I'll either add this one here, or he can pick it up into the spi tree.

I've skipped these for now, I think I'll just resend them after the
merge window.

Sorry for the delay. I hope this works out and I didn't miss any additional
compile-time dependencies.
