[PATCH 01/23] gpio: remove deps on ARCH_[WANT_OPTIONAL|REQUIRE]_GPIOLIB

[Linus Walleij]

The GPIOLIB symbol currently require that
ARCH_WANT_OPTIONAL_GPIOLIB or ARCH_REQUIRE_GPIOLIB is selected
to be selectable.

The ARCH_REQUIRE_GPIOLIB does only one thing: select GPIOLIB.

This is just confusing: architectures that want GPIOLIB should
be able to configure it in no matter what, and those who
require it should just select GPIOLIB.

It also creates problems for drivers that need to state
"select GPIOLIB" to get dependencies: those depend on the
selected architecture to select
ARCH_[WANT_OPTIONAL|REQUIRE]_GPIOLIB first, and will cause
compile errors for the few archs that state neither.

These intermediary symbols need to go.

As a first step, remove the dependencies so that:

- ARCH_WANT_OPTIONAL_GPIOLIB becomes a noop (GPIOLIB will be
  available for everyone) and

- "select ARCH_REQUIRE_GPIOLIB" can be replaced by just
  "select GPIOLIB"

After this patch we can follow up with patches cleaning up the
architectures one-by one and eventually remove the
ARCH_[WANT_OPTIONAL|REQUIRE]_GPIOLIB symbols altogether.

Various arch maintainers:

either ACK this and I will merge it into the GPIO tree for v4.7
anticipating no clashes, or you wait until I have the enabling patch
upstream (patch 1 in this series, removing deps on
ARCH_[WANTS_OPTIONAL|REQUIRES]_GPIOLIB), and you will be able to
merge it to your arch trees yourselves for late v4.7
(post GPIO tree merge) or for v4.8.

You can also ask me for an immutable branch if you prefer that, I
will put the enabling patch on a branch and the patch for your arch
on top and ask you to pull it.

Select your option from the menu, silence probably means I will
merge it to the GPIO tree. Unless you are X86 or ARM in which case
I will be cautious.

[PATCH 03/23] ARM: do away with ARCH_[WANT_OPTIONAL|REQUIRE]_GPIOLIB

[Linus Walleij]

This replaces:

- "select ARCH_REQUIRE_GPIOLIB" with "select GPIOLIB" as this can
  now be selected directly.

- "select ARCH_WANT_OPTIONAL_GPIOLIB" with no dependency: GPIOLIB
  is now selectable by everyone, so we need not declare our
  intent to select it.

When ordering the symbols the following rationale was used:
if the selects were in alphabetical order, I moved select GPIOLIB
to be in alphabetical order, but if the selects were not
maintained in alphabetical order, I just replaced
"select ARCH_REQUIRE_GPIOLIB" with "select GPIOLIB".

[PATCH 03/23] ARM: do away with ARCH_[WANT_OPTIONAL|REQUIRE]_GPIOLIB

[Linus Walleij]

This replaces:

- "select ARCH_REQUIRE_GPIOLIB" with "select GPIOLIB" as this can
  now be selected directly.

- "select ARCH_WANT_OPTIONAL_GPIOLIB" with no dependency: GPIOLIB
  is now selectable by everyone, so we need not declare our
  intent to select it.

When ordering the symbols the following rationale was used:
if the selects were in alphabetical order, I moved select GPIOLIB
to be in alphabetical order, but if the selects were not
maintained in alphabetical order, I just replaced
"select ARCH_REQUIRE_GPIOLIB" with "select GPIOLIB".

Various arch maintainers:

either ACK this and I will merge it into the GPIO tree for v4.7
anticipating no clashes, or you wait until I have the enabling patch
upstream (patch 1 in this series, removing deps on
ARCH_[WANTS_OPTIONAL|REQUIRES]_GPIOLIB), and you will be able to
merge it to your arch trees yourselves for late v4.7
(post GPIO tree merge) or for v4.8.

You can also ask me for an immutable branch if you prefer that, I
will put the enabling patch on a branch and the patch for your arch
on top and ask you to pull it.

Select your option from the menu, silence probably means I will
merge it to the GPIO tree. Unless you are X86 or ARM in which case
I will be cautious.

[PATCH 04/23] arm64: do away with ARCH_[WANT_OPTIONAL|REQUIRE]_GPIOLIB

[Linus Walleij]

This replaces:

- "select ARCH_REQUIRE_GPIOLIB" with "select GPIOLIB" as this can
  now be selected directly.

- "select ARCH_WANT_OPTIONAL_GPIOLIB" with no dependency: GPIOLIB
  is now selectable by everyone, so we need not declare our
  intent to select it.

Various arch maintainers:

either ACK this and I will merge it into the GPIO tree for v4.7
anticipating no clashes, or you wait until I have the enabling patch
upstream (patch 1 in this series, removing deps on
ARCH_[WANTS_OPTIONAL|REQUIRES]_GPIOLIB), and you will be able to
merge it to your arch trees yourselves for late v4.7
(post GPIO tree merge) or for v4.8.

You can also ask me for an immutable branch if you prefer that, I
will put the enabling patch on a branch and the patch for your arch
on top and ask you to pull it.

Select your option from the menu, silence probably means I will
merge it to the GPIO tree. Unless you are X86 or ARM in which case
I will be cautious.

Various arch maintainers:

either ACK this and I will merge it into the GPIO tree for v4.7
anticipating no clashes, or you wait until I have the enabling patch
upstream (patch 1 in this series, removing deps on
ARCH_[WANTS_OPTIONAL|REQUIRES]_GPIOLIB), and you will be able to
merge it to your arch trees yourselves for late v4.7
(post GPIO tree merge) or for v4.8.

You can also ask me for an immutable branch if you prefer that, I
will put the enabling patch on a branch and the patch for your arch
on top and ask you to pull it.

Select your option from the menu, silence probably means I will
merge it to the GPIO tree. Unless you are X86 or ARM in which case
I will be cautious.

[Linus Walleij]

This replaces:

- "select ARCH_REQUIRE_GPIOLIB" with "select GPIOLIB" as this can
  now be selected directly.

- "select ARCH_WANT_OPTIONAL_GPIOLIB" with no dependency: GPIOLIB
  is now selectable by everyone, so we need not declare our
  intent to select it.

When ordering the symbols the following rationale was used:
if the selects were in alphabetical order, I moved select GPIOLIB
to be in alphabetical order, but if the selects were not
maintained in alphabetical order, I just replaced
"select ARCH_REQUIRE_GPIOLIB" with "select GPIOLIB".

[PATCH 12/23] powerpc: do away with ARCH_[WANT_OPTIONAL|REQUIRE]_GPIOLIB

[Linus Walleij]

This replaces:

- "select ARCH_REQUIRE_GPIOLIB" with "select GPIOLIB" as this can
  now be selected directly.

- "select ARCH_WANT_OPTIONAL_GPIOLIB" with no dependency: GPIOLIB
  is now selectable by everyone, so we need not declare our
  intent to select it.

When ordering the symbols the following rationale was used:
if the selects were in alphabetical order, I moved select GPIOLIB
to be in alphabetical order, but if the selects were not
maintained in alphabetical order, I just replaced
"select ARCH_REQUIRE_GPIOLIB" with "select GPIOLIB".

Various arch maintainers:

either ACK this and I will merge it into the GPIO tree for v4.7
anticipating no clashes, or you wait until I have the enabling patch
upstream (patch 1 in this series, removing deps on
ARCH_[WANTS_OPTIONAL|REQUIRES]_GPIOLIB), and you will be able to
merge it to your arch trees yourselves for late v4.7
(post GPIO tree merge) or for v4.8.

You can also ask me for an immutable branch if you prefer that, I
will put the enabling patch on a branch and the patch for your arch
on top and ask you to pull it.

Select your option from the menu, silence probably means I will
merge it to the GPIO tree. Unless you are X86 or ARM in which case
I will be cautious.

[PATCH 13/23] sh: do away with ARCH_[WANT_OPTIONAL|REQUIRE]_GPIOLIB

[Linus Walleij]

This replaces:

- "select ARCH_REQUIRE_GPIOLIB" with "select GPIOLIB" as this can
  now be selected directly.

- "select ARCH_WANT_OPTIONAL_GPIOLIB" with no dependency: GPIOLIB
  is now selectable by everyone, so we need not declare our
  intent to select it.

When ordering the symbols the following rationale was used:
if the selects were in alphabetical order, I moved select GPIOLIB
to be in alphabetical order, but if the selects were not
maintained in alphabetical order, I just replaced
"select ARCH_REQUIRE_GPIOLIB" with "select GPIOLIB".

Various arch maintainers:

either ACK this and I will merge it into the GPIO tree for v4.7
anticipating no clashes, or you wait until I have the enabling patch
upstream (patch 1 in this series, removing deps on
ARCH_[WANTS_OPTIONAL|REQUIRES]_GPIOLIB), and you will be able to
merge it to your arch trees yourselves for late v4.7
(post GPIO tree merge) or for v4.8.

You can also ask me for an immutable branch if you prefer that, I
will put the enabling patch on a branch and the patch for your arch
on top and ask you to pull it.

Select your option from the menu, silence probably means I will
merge it to the GPIO tree. Unless you are X86 or ARM in which case
I will be cautious.
