[PATCH v3 0/2] arm64: dts: imx8mn: add 8MNANOD3L-EVK device tree

[Michael Walle]

Add support for the 8MNANOD3L-EVK which features a NXP IMX8MN SoC.

Patch 1 was formerly postet separately, but never picked up. So I've bumped
its version and added the actual device tree. Please note, there wasn't a
v1 nor a v2 of patch 2.

[PATCH v3 2/2] arm64: dts: imx8mn: add 8MNANOD3L-EVK device tree

[Michael Walle]

Add a device tree for the 8MNANOD3L-EVK eval board which features an
IMX8MN SoC. It is similar to the 8MNANODLPD4-EVK eval board except it
has an IMX8MN UltraLite SoC and DDR3L memory. It esp. differs in the
PMIC configuration because the SoC has a smaller package and thus the
ARM core voltage is combined with the SoC voltage and the DDR voltage
is 1.35V for the DDR3L memory.

Applied both, thanks!
