#1680649 — [PATCH] gpio: drop unnecessary includes from include/linux/gpio/driver.h

From	Masahiro Yamada <yamada.masahiro@socionext.com>
Date	2017-07-04 06:00 +0200
Subject	[PATCH] gpio: drop unnecessary includes from include/linux/gpio/driver.h
Message-ID	<tZnah-2HZ-5@gated-at.bofh.it>

Some of include directives in include/linux/gpio/driver.h are
unneeded because the header does not need to know the content of
struct device, irq_chip, etc.  Just declare they are structures.

On the other hand, <linux/irqhandler.h> and <linux/spinlock_types.h>
turned out to be necessary for irq_flow_handler_t and spinlock_t,
respectively.

Each driver should include what it needs without relying on what is
implicitly included from <linux/gpio/driver.h>.  This will cut down
unnecessary header parsing.

If Linus is okay with the following proposal I would rather go with it,
i.e. logical split the series to

1. Fix IRQ related headers inclusion
2. Fix pinconf-generic.h inclusion
3. Fix OF headers inclusion (btw, of_gpio.h is not enough there?)

In any case take my tag

Maybe
  4.  Fix (platform_)device inclusion


But, I do not see much sense to touch headers multiple times.

The changes to the above drivers look fine to me:

Acked-by: William Breathitt Gray <vilhelm.gray@gmail.com>

However, this patch as a whole does too many things; I'd like to see it
split-up logically similar to how Andy Shevchenko suggested in his
reply. That should allow ACKs by respective driver maintainers to be
accounted more properly.

I was missing a very important thing.

<linux/gpio/driver.h> is used in various subsystems.

I tested only under drivers/gpio/, but
drivers/pinctrl/ is one of the biggest source of compile errors.

(Probably I will get reports from kbuild test robot.)


So, I need to think about how to merge this (if the basic idea of this is OK).

Maybe,

[1] Send patches to subsystems (gpio, pinctrl, etc.) for v4.14
[2] Drop unneeded includes from linux/gpio/driver.h for v4.15

Perhaps, fixing users (drivers!) first. then frameworks / libraries,
at last header itself (in each case perhaps follow the split I
proposed earlier).

My wish is to get gpiolib-acpi patch completely separate from the bunch.
