kernel/include/linux/spi/rspi.h, branch linux-3.17.yHosts the 0x221E linux distro kernel.https://universe.0xinfinity.dev/distro/kernel/atom?h=linux-3.17.y2014-06-02T14:49:32Zspi: rspi: Remove unused 16-bit DMA support2014-06-02T14:49:32ZGeert Uytterhoevengeert+renesas@glider.be2014-06-02T13:38:05Zurn:sha1:9c5de2c1754c2bb3c69c4d7bf0d0edc0a61d8232
The 16-bit DMA support doesn't fit well within the SPI core DMA framework,
as it needs to manage its own double-sized temporary buffers, for handling
the interleaved data.
Remove it, as there is no in-tree board code that sets
rspi_plat_data.dma_width_16bit.

spi/rspi: add dmaengine support2012-05-20T04:37:16ZShimoda, Yoshihiroyoshihiro.shimoda.uh@renesas.com2012-04-20T05:50:36Zurn:sha1:a3633fe7aa7022e2e9b2b799a0cbf3d6944d8ba5
This patch adds dmaengine supporting using sh_dma driver. The module
receives data by DMAC, it also needs TX DMAC to generate SPI's clocks.
