a8e59744e1 gpiolib: split linux/gpio/driver.h out of linux/gpio.h
Almost all gpio drivers include linux/gpio/driver.h, and other
files should not rely on includes from this header.

Remove the indirect include from here and include the correct
headers directly from where they are used.

d74e316633 gpiolib: remove legacy gpio_export()
There are only a handful of users of gpio_export() and
related functions.

As these are just wrappers around the modern gpiod_export()
helper, remove the wrappers and open-code the gpio_to_desc
in all callers to shrink the legacy API.

94d20f7d67 gpiolib: coldfire: remove custom asm/gpio.h
Now that coldfire is the only user of a custom asm/gpio.h, it seems
better to remove this as well, and have the same interface everywhere.

For the gpio_get_value()/gpio_set_value()/gpio_to_irq(), gpio_cansleep()
functions, the custom version is only a micro-optimization to inline the
function for constant GPIO numbers. However, in the coldfire defconfigs,
I was unable to find a single instance where this micro-optimization
was even used, and according to Geert the only user appears to be the
QSPI chip that is disabled everywhere.

The custom gpio_request_one() function is even less useful, as it is
guarded by an #ifdef that is never true.

ee5a66d87c gpiolib: remove empty asm/gpio.h files
The arm and sh versions of this file are identical to the generic
versions and can just be removed.

The drivers that actually use the sh3 specific version also include
cpu/gpio.h directly, with the exception of magicpanelr2, which is
easily fixed. This leaves coldfire as the only gpio driver
that needs something custom for gpiolib.

d49765b5f4 gpio: GPIO_REGMAP: select REGMAP instead of depending on it
REGMAP is a hidden (not user visible) symbol. Users cannot set it
directly thru "make *config", so drivers should select it instead of
depending on it if they need it.

Consistently using "select" or "depends on" can also help reduce
Kconfig circular dependency issues.

Therefore, change the use of "depends on REGMAP" to "select REGMAP".

are used to identify modules. As a consequence, uses of the macro

might succeed rather than failing with a suitable error message.

So remove it in the files in this commit, none of which can be built as

On several R-Car Gen3(e) SoCs, multiple (up to 4) operating points in
the same cluster are marked with the "turbo-mode" property, which is
meant only for operating points beyond "Normal Mode".

Fix this by dropping the property from all operating points but the
"High Performance" one.

The RZ/V2M EVK comes with a slot for a uSD card, and an eMMC.
Add support for the both of them.

Please note that the pinctrl driver for RZ/V2M doesn't support
interrupts yet, therefore the card detect pin has been connected
to the SDHI IP directly in this patch.
We'll connect the card detect pin to its corresponding GPIO when
we'll have driver support for interrupts in the RZ/V2M pinctrl
driver.

68d94cca3b gpio: remove MODULE_LICENSE in non-modules
Since commit 8b41fc4454 ("kbuild: create modules.builtin without
Makefile.modbuiltin or tristate.conf"), MODULE_LICENSE declarations
are used to identify modules. As a consequence, uses of the macro
in non-modules will cause modprobe to misidentify their containing
object file as a module when it is not (false positives), and modprobe
might succeed rather than failing with a suitable error message.

So remove it in the files in this commit, none of which can be built as
modules.
