Subject: [PATCH] riscv: dts: allwinner: d1: Add SPI0 controller node
Date:   Fri,  5 May 2023 10:46:51 +0300
Message-Id: <20230505074701.1030980-1-bigunclemax@gmail.com>

Some boards form the MangoPi family (MQ\MQ-Dual\MQ-R) may have
an optional SPI flash that connects to the SPI0 controller.
This controller is already supported by sun8i-h3-spi driver.
So let's add its DT node.
