+Subject: [PATCH] arm64: allwinner: a64: add SPI nodes
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The A64 SPI controllers are register compatible to the h3/h5 SPI
+controllers.
+
+The A64 has two SPI controllers, each with a single chip select.
+The handles for the DMA channels (23/24 for SPI0/SPI1) are omitted,
+as the A64 DMA support is currently missing.
