[PATCH v3 2/8] arm64: dts: sparx5: Add SPI controller and SPI mux

From: Lars Povlsen
Date: Thu Jul 02 2020 - 06:14:32 EST


This adds a SPI controller to the Microchip Sparx5 SoC, as well as the
SPI bus interface mux, which may optionally be needed for selecting
between alternate SPI bus segments (SPI/SPI2).
