[PATCH v2 0/6] arm: imx8mp: add karo electronics qsxp imx8mp som support

[Stefan Kerkmann]

The Ka-Ro QSXP[1] is a i.MX8M Plus solder down system on module. This
series adds support for the SOM itself on the QSBASE4 RDK. For ethernet
support on the QSBASE4 RDK, the Micrel phy driver gains support for the
KSZ9131 gigabit ethernet phy.

[PATCH v2 4/6] arm: dts: karo: import dts for karo-qsxp-ml81

[Stefan Kerkmann]

From: Marc Kleine-Budde <mkl@pengutronix.de>

This imports the device tree for the Ka-Ro QSXP, which is a i.MX8M Plus
solder down system on module. The sources have been adapted from the
offical Ka-Ro github[1], commit a49b38ec97854c0cd9cd83a9f4ae3b56e99a58b6.

[PATCH v2 5/6] arm: dts: karo: add karo imx8mp-karo-qsxp-ml81-qsbase4

[Stefan Kerkmann]

The Ka-Ro QSXP-QSBASE4[1] is the offical DK from Ka-Ro for their QSXP
i.MX8M Plus solder down system on module. It comes with an additional
Micrel KSZ9131 gigabit ethernet phy. The devicetree was adapted from the
offical Ka-Ro github[2], commit a49b38ec97854c0cd9cd83a9f4ae3b56e99a58b6.
