Pull pin control updates from Linus Walleij:
 "This is the bulk of pin control changes for the v4.8 kernel cycle.

  Nothing stands out as especially exiting: new drivers, new subdrivers,
  lots of cleanups and incremental features.

  Business as usual.

  New drivers:

   - New driver for Oxnas pin control and GPIO.  This ARM-based chipset
     is used in a few storage (NAS) type devices.

   - New driver for the MAX77620/MAX20024 pin controller portions.

   - New driver for the Intel Merrifield pin controller.

  New subdrivers:

   - New subdriver for the Qualcomm MDM9615

   - New subdriver for the STM32F746 MCU

   - New subdriver for the Broadcom NSP SoC.

  Cleanups:

   - Demodularization of bool compiled-in drivers.

  Apart from this there is just regular incremental improvements to a
  lot of drivers, especially Uniphier and PFC"

pinctrl: mediatek: fix suspend/resume timing issue

2016-06-08T08:09:40+00:00

An irq which is a wake up source maybe masked unexpectedly if the wake
up source irq was triggered after pinctrl irqchip suspend and before
suspend_device_irqs finished.
Use *_noirq callbacks to guarantee pinctrl irqchip suspend would be
called after suspend_devices_irqs.

pinctrl: mediatek: fix dual-edge code defect

2016-05-31T08:13:45+00:00

When a dual-edge irq is triggered, an incorrect irq will be reported on
condition that the external signal is not stable and this incorrect irq
has been registered.
Correct the register offset.

Merge tag 'pinctrl-v4.7-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl

2016-05-19T19:50:56+00:00

Pull pin control updates from Linus Walleij:
 "This kernel cycle was quite calm when it comes to pin control and
  there is really just one major change, and that is the introduction of
  devm_pinctrl_register() managed resources.

  Apart from that linear development, details below.

  Core changes:

   - Add the devm_pinctrl_register() API and switch all applicable
     drivers to use it, saving lots of lines of code all over the place.

  New drivers:

   - driver for the Broadcom NS2 SoC

   - subdriver for the PXA25x SoCs

   - subdriver for the AMLogic Meson GXBB SoC

  Driver improvements:

   - the Intel Baytrail driver now properly supports pin control

   - Nomadik, Rockchip, Broadcom BCM2835 support the .get_direction()
     callback in the GPIO portions

   - continued development and stabilization of several SH-PFC SoC
     subdrivers: r8a7795, r8a7790, r8a7794 etc"

pinctrl: mediatek: correct debounce time unit in mtk_gpio_set_debounce

2016-04-15T08:28:04+00:00

The debounce time unit for gpio_chip.set_debounce is us but
mtk_gpio_set_debounce regard it as ms.
Fix this by correct debounce time array dbnc_arr so it can find correct
debounce setting. Debounce time for first debounce setting is 500us,
correct this as well.

While I'm at it, also change the debounce time array name to
"debounce_time" for readability.

pinctrl: Rename pinctrl_utils_dt_free_map to pinctrl_utils_free_map

2016-04-01T13:06:36+00:00

Rename pinctrl_utils_dt_free_map to pinctrl_utils_free_map, since
it does not depend on device tree despite the current name. This
will enforce a consistent naming in pinctr-utils.c and will make
it clear it can be called from outside device tree (e.g. from
ACPI handling code).

pinctrl: pinctrl-mt6397 driver explicitly non-modular

2016-03-09T03:22:54+00:00

The Kconfig for this driver is currently:

config PINCTRL_MT6397
        bool "Mediatek MT6397 pin control" if COMPILE_TEST && !MFD_MT6397

...meaning that it is currently 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_init translates to device_initcall in the non-modular
case, the init ordering remains unchanged with this commit.

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

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