   4 Subject: [PATCH] arm64: allwinner: a64: add SPI nodes
   5 MIME-Version: 1.0
   6 Content-Type: text/plain; charset=UTF-8
   7 Content-Transfer-Encoding: 8bit
   8
   9 The A64 SPI controllers are register compatible to the h3/h5 SPI
  10 controllers.
  11
  12 The A64 has two SPI controllers, each with a single chip select.
  13 The handles for the DMA channels (23/24 for SPI0/SPI1) are omitted,
  14 as the A64 DMA support is currently missing.
