This patchset is used to fix a host version register bug in the T4240-R1.0-R2.0
eSDHC controller. To get the SoC version and revision, it's needed to add the
GUTS driver to access the global utilities registers.
So, the first three patches are to add the GUTS driver.
The following two patches are to enable GUTS driver support to get SVR in eSDHC
driver and fix host version for T4240.
Yangbo Lu (5):
ARM64: dts: ls2080a: add device configuration node
soc: fsl: add GUTS driver for QorIQ platforms
dt: move guts devicetree doc out of powerpc directory
powerpc/fsl: move mpc85xx.h to include/linux/fsl
mmc: sdhci-of-esdhc: fix host version for T4240-R1.0-R2.0
