      pinctrl: imx50: make it explicitly non-modular · 4415db17
      Paul Gortmaker authored
      The Kconfig currently controlling compilation of this code is:
      
      drivers/pinctrl/freescale/Kconfig:config PINCTRL_IMX50
      drivers/pinctrl/freescale/Kconfig:	bool "IMX50 pinctrl driver"
      
      ...meaning that it currently is 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 was not in use by this driver, 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.

      pinctrl: OF: Don't create a pinctrl handle if no pinctrl entries exist · 98849fa0
      Jon Hunter authored
      When pinctrl_get() is called for a device, it will return a valid handle
      even if the device itself has no pinctrl state entries defined in
      device-tree. This is caused by the function pinctrl_dt_to_map() which
      will return success even if the first pinctrl state, 'pinctrl-0', is not
      found in the device-tree node for a device.
      
      According to the pinctrl device-tree binding documentation, pinctrl
      states must be numbered starting from 0 and so 'pinctrl-0' should always
      be present if a device uses pinctrl and therefore, if 'pinctrl-0' is not
      present it seems valid that we should not return a valid pinctrl handle.
      
      Fix this by returning an error code if the property 'pinctrl-0' is not
      present for a device.

      pinctrl: intel: Prevent force threading of the interrupt handler · 1a7d1cb8
      Mika Westerberg authored
      The pinctrl-intel needs to use request_irq() instead of chained interrupt
      handling because it shares the interrupt with multiple GPIO host
      controllers found on Intel CPUs. In -rt all such interrupts are forced to
      run in thread context which triggers following warning:

      The handle_irq_event_* functions (and I suppose generic_handle_irq()) is
      expected to be called with interrupts disabled and they rightfully complain
      here because we run in thread context with interrupts enabled.
      
      Fix this by adding IRQF_NO_THREAD flag when the master interrupt is
      requested. This prevents forced threading of the interrupt used by the GPIO
      host controllers.

      The reason why this happens is because intel_gpio_irq_ack() is called with
      desc->lock raw_spinlock locked which cannot sleep but our normal spinlock
      (which is converted to rtmutex in -rt) is allowed to sleep. This causes
      might_sleep() to trigger.
      
      Fix this by converting the normal spinlock to a raw_spinlock.

      pinctrl: Always recurse into bcm folder · f886031f
      Florian Fainelli authored
      drivers/pinctrl/bcm/Makefile properly builds individual drivers based on
      their respective Kconfig symbols. ARCH_BCM is currently a menuconfig
      option from arch/arm/mach-bcm/Kconfig, which is fine, but prevents ARM64
      platforms which do not have such menuconfig option from building their
      pinctrl drivers, so let's get rid of that dependency.

      pinctrl: nomadik: fix warnings from unexported functions · 27cdb5d0
      Ben Dooks authored
      There are five functions in the driver that are defined but
      only used locally. Since these are not used in the current
      kernel, delete them to avoid the following warnings:
      
      drivers/pinctrl/nomadik/pinctrl-nomadik.c:1036:6: warning: symbol 'nmk_gpio_clocks_enable' was not declared. Should it be static?
      drivers/pinctrl/nomadik/pinctrl-nomadik.c:1050:6: warning: symbol 'nmk_gpio_clocks_disable' was not declared. Should it be static?

      pinctrl: at91-pio4: make it explicitly non-modular · f703851a
      Paul Gortmaker authored
      The Kconfig currently controlling compilation of this code is:
      
      drivers/pinctrl/Kconfig:config PINCTRL_AT91PIO4
      drivers/pinctrl/Kconfig:        bool "AT91 PIO4 pinctrl driver"
      
      ...meaning that it currently is 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.
      
      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.
      
      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.
