Subject: [v11, 0/8] Fix eSDHC host version register bug

This patchset is used to fix a host version register bug in the T4240-R1.0-R2.0
eSDHC controller. To match the SoC version and revision, 10 previous version
patchsets had tried many methods but all of them were rejected by reviewers.
Such as
	- dts compatible method
	- syscon method
	- ifdef PPC method
	- GUTS driver getting SVR method
Anrd suggested a soc_device_match method in v10, and this is the only available
method left now. This v11 patchset introduces the soc_device_match interface in
soc driver.

The first six patches are to add the GUTS driver. This is used to register a
soc device which contain soc version and revision information.
The following two patches introduce the soc_device_match method in soc driver
and apply it on esdhc driver to fix this bug.

Yangbo Lu (8):
  dt: bindings: update Freescale DCFG compatible
  ARM64: dts: ls2080a: add device configuration node
  dt: bindings: move guts devicetree doc out of powerpc directory
  powerpc/fsl: move mpc85xx.h to include/linux/fsl
  soc: fsl: add GUTS driver for QorIQ platforms
  MAINTAINERS: add entry for Freescale SoC drivers
  base: soc: introduce soc_device_match() interface
  mmc: sdhci-of-esdhc: fix host version for T4240-R1.0-R2.0
