[PATCH v4 03/10] arm64: dts: sparx5: Add basic cpu support

From: Lars Povlsen <hidden>
Date: 2020-07-27 08:42:40
Also in: linux-arm-kernel, linux-clk, linux-gpio, lkml
Subsystem: arm and arm64 soc sub-architectures (common parts), arm/microchip (arm64) soc support, arm/microchip sparx5 soc support, the rest · Maintainers: Arnd Bergmann, Krzysztof Kozlowski, Alexandre Belloni, Linus Walleij, Conor Dooley, Nicolas Ferre, Claudiu Beznea, Steen Hegelund, Daniel Machon, Linus Torvalds

This adds the basic DT structure for the Microchip Sparx5 SoC, and the
reference boards, pcb125, pcb134 and pcb135. The two latter have a
NAND vs a eMMC centric variant (as a mount option).
