    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"
