Merge tag 'leds_for_4.12' of git://git.kernel.org/pub/scm/linux/kernel/git/j.anaszewski/linux-leds

Pull LED updates from Jacek Anaszewski:
 "New drivers:

   - add LED support for MT6323 PMIC

   - add LED support for Motorola CPCAP PMIC

  New features and improvements:

   - add LED trigger for all CPUs aggregated which is useful on tiny
     boards with more CPU cores than LED pins

   - add OF variants of LED registering functions as a preparation for
     adding generic support for Device Tree parsing

   - dell-led improvements and cleanups, followed by moving it to the
     x86 platform driver subsystem which is a more appropriate place for
     it

   - extend pca9532 Device Tree support by adding the LEDs
     'default-state' property

   - extend pca963x Device Tree support by adding nxp,inverted-out
     property for inverting the polarity of the output

   - remove ACPI support for lp3952 since it relied on a non-official
     ACPI IDs"
