cfb12c8952 arm64: dts: imx8mn-ddr4-evk: correct ldo1/ldo2 voltage range
Correct ldo1 voltage range from wrong high group(3.0V~3.3V) to low group
(1.6V~1.9V) because the ldo1 should be 1.8V. Actually, two voltage groups
have been supported at bd718x7-regulator driver, hence, just corrrect the
voltage range to 1.6V~3.3V. For ldo2@0.8V, correct voltage range too.
Otherwise, ldo1 would be kept @3.0V and ldo2@0.9V which violate i.mx8mn
datasheet as the below warning log in kernel:

[    0.995524] LDO1: Bringing 1800000uV into 3000000-3000000uV
[    0.999196] LDO2: Bringing 800000uV into 900000-900000uV

0376f6ec9e arm64: dts: imx8m: Add ddr controller nodes
This is used by the imx-ddrc devfreq driver to implement dynamic
frequency scaling of DRAM.

Support for proactive scaling via interconnect will come later. The
high-performance bus masters which need that (display, vpu, gpu) are
mostly not yet enabled in upstream anyway.

791b02da0a arm64: dts: imx8mn: Create EVK dtsi file for common use
i.MX8MN has different EVK boards to support different DDR types,
the ONLY differences are DDR chips and PMIC, so most of the devices
can be shared between these EVK boards, create a EVK dtsi file for
common use.

0bd0512d06 arm64: dts: imx8mn: Move usdhc clocks assignment to board DT
usdhc's clock rate is different according to different devices
connected, so clock rate assignment should be placed in board
DT according to different devices connected on each usdhc port.

caa2ac2972 arm64: dts: imx8mn-ddr4-evk: Move iomuxc node to end of file
All nodes are better to follow alphabetical sort except iomuxc
which has huge pinctrl data, better to put it at the end of
file.
