[PATCH 0/2] arm64: add support for Olimex i.MX8MP-SOM-EVB kit

[Zoltan HERPAI]

This series adds support for the Olimex i.MX8MP-SOM-EVB kit, consisting of a carrier
board and a SoM.

Patch 1/2 documents the respective bindings,
Patch 2/2 adds the SoM dtsi and the carrier board dts.

[PATCH 2/2] arm64: dts: imx8mp: add Olimex i.MX8MP-SOM-EVB kit

[Zoltan HERPAI]

This adds support for an i.MX8-based system-on-module + EVB board. The
product pages are here [1] and here [2] respectively.

There are two new files, one dts for the EVB and one dtsi for the SoM.

EVB features:
 - microSD slot, eMMC headers
 - 2x Ethernet 1Gb
 - 2x USB 3.0
 - 1x m.2 PCIe slot
 - 2x CAN interface
 - audio (2x jacks via ES8328)
 - at24 eeprom
 - separate UARTs for the A53 and the M7 cores
 - HDMI
 - UEXT and GPIO connectors with I2C available

SoM features:
 - NXP i.MX8MP @ 1600MHz
 - 4GByte memory
 - LVDS interface
 - 2x MIPI_CSI, 1x MIPI_DSI
 - status LED
