Pull pin control updates from Linus Walleij:
 "Pin control bulk changes for the v4.11 kernel cycle.

  Core changes:

   - Switch the generic pin config argument from 16 to 24 bits, only use
     8 bits for the configuration type. We might need to encode more
     information about a certain setting than we need to encode
     different generic settings.

   - Add a cross-talk API to the pin control GPIO back-end, utilizing
     pinctrl_gpio_set_config() from GPIO drivers that want to set up a
     certain pin configuration in the back-end.

     This also includes the .set_config() refactoring of the GPIO chips,
     so that they pass a generic configuration for things like
     debouncing and single ended (typically open drain). This change has
     also been merged in an immutable branch to the GPIO tree.

   - Take hogs with a delayed work, so that we finalize probing a pin
     controller before trying to get any hogs.

   - For pin controllers putting all group and function definitions into
     the device tree, we now have generic code to deal with this and it
     is used in two drivers so far.

   - Simplifications of the pin request conflict check.

   - Make dt_free_map() optional.

  Updates to drivers:

   - pinctrl-single now use the generic helpers to generate dynamic
     group and function tables from the device tree.

   - Texas Instruments IOdelay configuration driver add-on to
     pinctrl-single.

   - i.MX: use radix trees to store groups and functions, use the new
     generic group and function helpers to manage them.

   - Intel: add support for hardware debouncing and 1K pull-down. New
     subdriver for the Gemini Lake SoC.

   - Renesas SH-PFC: drive strength and bias support, CAN bus muxing,
     MSIOF, SDHI, HSCIF for r8a7796. Gyro-ADC supporton r8a7791.

   - Aspeed: use syscon cross-dependencies to set up related bits in the
     LPC host controller and display controller.

   - Aspeed: finalize G4 and G5 support. Fix mux configuration on GPIOs.
     Add banks Y, Z, AA, AB and AC.

   - AMD: support additional GPIO.

   - STM32: set this controller to strict muxing mode. STM32H743 MCU
     support.

   - Allwinner sunxi: deep simplifications on how to support subvariants
     of SoCs without adding to much SoC-specific data for each
     subvariant, especially for sun5i variants. New driver for V3s SoCs.
     New driver for the H5 SoC. Support A31/A31s variants with the new
     variant framework.

   - Mvebu: simplifications to use a MMIO and regmap abstraction. New
     subdrivers for the 98DX3236, 98DX5241 SoCs.

   - Samsung Exynos: delete Exynos4415 support. Add crosstalk to the SoC
     driver to access regmaps. Add infrastructure for pin-bank retention
     control. Clean out the pin retention control from
     arch/arm/mach-exynos and arch/arm/mach-s5p and put it properly in
     the Samsung pin control driver(s).

   - Meson: add HDMI HPD/DDC pins. Add pwm_ao_b pin.

   - Qualcomm: use raw spinlock variants: this makes the qualcomm driver
     realtime-safe"

pinctrl: samsung: Fix return value check in samsung_pinctrl_get_soc_data()

In case of error, the function devm_ioremap() returns NULL pointer not
ERR_PTR(). Fix by using devm_ioremap_resource instead of devm_ioremap.

pinctrl: berlin: make bool drivers explicitly non-modular

2017-02-13T13:25:55+00:00

None of the Kconfigs for any of these drivers are tristate,
meaning that they currently are not being built as a module by anyone.

Lets remove the modular code that is essentially orphaned, so that
when reading the driver there is no doubt it is builtin-only.

Since module_platform_driver() uses the same init level priority as
builtin_platform_driver() the init ordering remains unchanged with
this commit.

Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.

We also delete the MODULE_LICENSE tag etc. since all that information
is already contained at the top of the file in the comments.

None of the Kconfigs for any of these drivers are tristate,
meaning that they currently are not being built as a module by anyone.

Lets remove the modular code that is essentially orphaned, so that
when reading the drivers there is no doubt they are builtin-only.  All
drivers get the exact same change, so they are handled in batch.

Changes are (1) use init.h header in place of module.h header,
(2) delete module_exit related code, (3) delete MODULE_DEVICE_TABLE,
and (4) delete MODULE_LICENCE/MODULE_AUTHOR and associated tags.

None of these drivers were using module_init() so we don't have to
worry about the init ordering getting changed with this commit.

Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.

We also delete the MODULE_LICENSE etc. tags since all that information
is already contained at the top of each file in the comments.

Lets remove the modular code that is essentially orphaned, so that
when reading the drivers there is no doubt they are builtin-only.
All drivers get the exact same change, so they are handled in batch.

Changes are (1) use builtin_platform_driver, (2) dont use module.h
(3) delete module_exit related code, (4) delete MODULE_DEVICE_TABLE,
and (5) delete MODULE_LICENCE/MODULE_AUTHOR and associated tags.

For the dove driver we explicitly disallow a driver unbind, since
that doesn't have a sensible use case anyway, and it allows us to
drop the ".remove" code for non-modular drivers.

Since module_platform_driver() uses the same init level priority as
builtin_platform_driver() the init ordering remains unchanged with
this commit.

We deleted the MODULE_LICENSE etc. tags since all that information

pinctrl: sunxi: make sun5i explicitly non-modular

2017-02-06T10:28:22+00:00

We had all these corrected in commit 0c8c6ba00cbf ("pinctrl: sunxi:
make bool drivers explicitly non-modular") but this new one recently
crept in.

The Kconfig currently controlling compilation of this code is:

   drivers/pinctrl/sunxi/Kconfig:config PINCTRL_SUN5I
   drivers/pinctrl/sunxi/Kconfig:  def_bool MACH_SUN5I

...meaning that it currently is not being built as a module by anyone.

Lets remove the couple traces of modular infrastructure use, so that
when reading the driver there is no doubt it is builtin-only.

Since module_platform_driver() uses the same init level priority as
builtin_platform_driver() the init ordering remains unchanged with
this commit.

Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.

We also delete the MODULE_LICENSE tag etc. since all that information

pinctrl: samsung: mark PM functions as __maybe_unused

2017-02-06T10:06:14+00:00

The rework of the suspend/resume handling uses the wrong #ifdef check, leading
to a build warning without CONFIG_PM_SLEEP:

drivers/pinctrl/samsung/pinctrl-samsung.c:1142:12: error: 'samsung_pinctrl_resume' defined but not used [-Werror=unused-function]
drivers/pinctrl/samsung/pinctrl-samsung.c:1092:12: error: 'samsung_pinctrl_suspend' defined but not used [-Werror=unused-function]

Using a __maybe_unused annotation instead of the #ifdef is a simple way to
avoid this problem class.
