Merge tag 'armsoc-drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc 

Pull ARM SoC driver updates from Arnd Bergmann:
 "This contains driver changes that are tightly connected to SoC
  specific code. Aside from smaller cleanups and bug fixes, here is a
  list of the notable changes.

  New device drivers:

   - The Turris Mox router has a new "moxtet" bus driver for its
     on-board pluggable extension bus. The same platform also gains a
     firmware driver.

   - The Samsung Exynos family gains a new Chipid driver exporting using
     the soc device sysfs interface

   - A similar socinfo driver for Qualcomm Snapdragon chips.

   - A firmware driver for the NXP i.MX DSP IPC protocol using shared
     memory and a mailbox

  Other changes:

   - The i.MX reset controller driver now supports the NXP i.MX8MM chip

   - Amlogic SoC specific drivers gain support for the S905X3 and A311D
     chips

   - A rework of the TI Davinci framebuffer driver to allow important
     cleanups in the platform code

   - A couple of device drivers for removed ARM SoC platforms are
     removed. Most of the removals were picked up by other maintainers,
     this contains whatever was left"

Description:	(R) Read input from the shift registers, in hexadecimal.

		Returns N+1 bytes, where N is the number of Moxtet connected

		modules. The first byte is from the CPU board itself.

		Example: 101214

			 10: CPU board with SD card

			 12: 2 = PCIe module, 1 = IRQ not active

			 14: 4 = Peridot module, 1 = IRQ not active

		Example: 0102

			 01: 01 was last written, or is to be written, to the

			     first module's shift register

			 02: the same for second module
