Subject: [PATCH 0/5] spi: uniphier: Introduce DMA transfer mode
Date: Tue, 24 Dec 2019 09:58:22 +0900 [thread overview]
Message-ID: <1577149107-30670-1-git-send-email-hayashi.kunihiko@socionext.com> (raw)
This series introduces DMA transfer mode into UniPhier SPI driver.
This only supports UniPhier XDMAC implemented in the SoC.
The DMA transfer mode uses FIFO threshold as a trigger to start DMA transfer,
however, the FIFO is limited to one word width due to alignment restiction
of the DMA controller.
Kunihiko Hayashi (5):
spi: uniphier: Fix FIFO threshold
spi: uniphier: Change argument of irq functions to private structure
spi: uniphier: Add handle_err callback function
spi: uniphier: Add SPI_LOOP to the capabilities
spi: uniphier: Add DMA transfer mode support
