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.
