Subject: ARM: dts: renesas: Minimize R8A779G0 V4H RPC SPI DT node
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=3faeb78378ea32922fbd00e9ddf675ce0aa526a3;p=u-boot.git

ARM: dts: renesas: Minimize R8A779G0 V4H RPC SPI DT node

The RPC SPI DT node is now part of mainline Linux DT, remove the
duplicate content from U-Boot DT extras. The SPI flash DT node name
has been changed from "spi-flash@0" to "flash@0", reflect this change
in this patch. Retain "bank-width" and "num-cs" DT properties which
are used by U-Boot. Retain "spi-rx-bus-width" and "spi-tx-bus-width"
DT properties to indicate the bus should always be operated in 1-1-1
mode as the U-Boot RPC SPI driver does not support higher bus width
modes yet.
