spi: sun4i: Set bits_per_word_mask to only support 8 bits word length 2014-03-04T03:08:05+00:00 Axel Lin axel.lin@ingics.com 2014-03-02T14:25:10+00:00 ba47644d5b79914fe53b69c639902afce8ccfe7f This controller only supports 8 bits word length. Set bits_per_word_mask so spi core will reject transfers that attempt to use an unsupported bits_per_word value.

spi: sunxi: Add Allwinner A10 SPI controller driver 2014-02-23T02:14:46+00:00 Maxime Ripard maxime.ripard@free-electrons.com 2014-02-22T21:35:53+00:00 b5f6517948cce50bde9aa441b4f00b63518f6421 The older Allwinner SoCs (A10, A13, A10s and A20) all have the same SPI controller. Unfortunately, this SPI controller, even though quite similar, is significantly different from the recently supported A31 SPI controller (different registers offset, split/merged registers, etc.). Supporting both controllers in a single driver would be unreasonable, hence the addition of a new driver. Like its more recent counterpart, it supports DMA, but the driver only does PIO until we have a dmaengine driver for this platform.
