fc54664e0b arm64: dts: imx8mm-evk: Align pin configuration group names with schema
Device tree schema expects pin configuration groups to end with 'grp'
suffix, otherwise dtbs_check complain with a warning like:

    ... do not match any of the regexes: 'grp$', 'pinctrl-[0-9]+'

aa71d06483 arm64: dts: imx8mm: Split the imx8mm evk board dts to a common dtsi
There are two type of i.MX8MM EVK board, one is populated with
LPDDR4(default dts), and one is populated with DDR4. these two
boards share most of the board design, but still have some difference.
imx8mm-evk has emmc support, imx8mm-ddr4-evk has gpmi nand support.
And also, the BT/WIFI module is different. So move the common dts
part into imx8mm-evk.dtsi for reuse.

Use preferred properties of phy node instead of deprecated
phy-reset-gpios (and others).  This avoids copying deprecated code into

4fd6b5735c arm64: dts: imx8mm-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.mx8mm
datasheet as the below warning log in kernel:

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

78cc25fa26 arm64: dts: imx8mm-evk: Add BD71847 PMIC
The BUCK2 regulator is used for cpufreq voltage control, otherwise
configuration is mostly static.

This uses the newly-implemented rohm,reset-snvs-powered property to
properly handle the SNVS state of imx8mm.

Between BD71837 and BD71847 the BUCK3/4 regulators were removed but
datasheet and board schematics kept the names for BUCK5/6/7/8. The
driver however renumbered 5/6/7/8 to 3/4/5/6. Use the names from DT
bindings and add comments to signal this.
