Merge tag 'pinctrl-v4.3-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl

Pull pin control updates from Linus Walleij:
 "This is the bulk of pin control changes for the v4.3 development
  cycle.

  Like with GPIO it's a lot of stuff.  If my subsystems are any sign of
  the overall tempo of the kernel v4.3 will be a gigantic diff.

[ It looks like 4.3 is calmer than 4.2 in most other subsystems, but
  we'll see - Linus ]

  Core changes:

   - It is possible configure groups in debugfs.

   - Consolidation of chained IRQ handler install/remove replacing all
     call sites where irq_set_handler_data() and
     irq_set_chained_handler() were done in succession with a combined
     call to irq_set_chained_handler_and_data().  This series was
     created by Thomas Gleixner after the problem was observed by
     Russell King.

   - Tglx also made another series of patches switching
     __irq_set_handler_locked() for irq_set_handler_locked() which is
     way cleaner.

   - Tglx also wrote a good bunch of patches to make use of
     irq_desc_get_xxx() accessors and avoid looking up irq_descs from
     IRQ numbers.  The goal is to get rid of the irq number from the
     handlers in the IRQ flow which is nice.

  Driver feature enhancements:

   - Power management support for the SiRF SoC Atlas 7.

   - Power down support for the Qualcomm driver.

   - Intel Cherryview and Baytrail: switch drivers to use raw spinlocks
     in IRQ handlers to play nice with the realtime patch set.

   - Rework and new modes handling for Qualcomm SPMI-MPP.

   - Pinconf power source config for SH PFC.

  New drivers and subdrivers:

   - A new driver for Conexant Digicolor CX92755.

   - A new driver for UniPhier PH1-LD4, PH1-Pro4, PH1-sLD8, PH1-Pro5,
     ProXtream2 and PH1-LD6b SoC pin control support.

   - Reverse-egineered the S/PDIF settings for the Allwinner sun4i
     driver.

   - Support for Qualcomm Technologies QDF2xxx ARM64 SoCs

   - A new Freescale i.mx6ul subdriver.

  Cleanup:

   - Remove platform data support in a number of SH PFC subdrivers"
