Subject: riscv: dts: allwinner: d1: Add SPI controllers node
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=c1b2093dce23158e758818443e059e3fcd54633e;p=linux.git

riscv: dts: allwinner: d1: Add SPI controllers node

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 the same for R329/D1/R528/T113s SoCs and
should be supported by the sun50i-r329-spi driver.

So let's add its DT nodes.
