Subject: [RESEND PATCH 1/2] arm64: allwinner: a64: add SPI nodes
Date: Tue, 29 Aug 2017 22:26:51 +0200	[thread overview]
Message-ID: <20170829202652.5476-2-stefan.bruens@rwth-aachen.de> (raw)
In-Reply-To: <20170829202652.5476-1-stefan.bruens@rwth-aachen.de>

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 controller node is currently missing.

Signed-off-by: Stefan Br?ns <stefan.bruens@rwth-aachen.de>
