[PATCH] arm64: dts: marvell: add ESPRESSObin variants

Tomasz Maciej Nowak tmn505 at gmail.com
Mon May 27 04:11:56 PDT 2019


This commit adds dts for different variants of ESPRESSObin board:

ESPRESSObin with soldered eMMC,

ESPRESSObin V7, compared to prior versions some passive elements changed
and ethernet ports labels positions have been reversed,

ESPRESSObin V7 with soldered eMMC.

Since most of elements are the same, one common dtsi is created and
referenced in each dts of particular variant.
