2015-11-18spi: sun4i: allow transfers to set transmission speedMarcus Weseloh
Allow transfers to set the transmission speed rather than using the device max_speed_hz value. The SPI core makes sure that the speed_hz value is always set on the transfer. Signed-off-by: Marcus Weseloh <mweseloh42@gmail.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2014-10-20spi: drop owner assignment from platform_driversWolfram Sang
A platform_driver does not need to set an owner, it will be populated by the driver core. Signed-off-by: Wolfram Sang <wsa@the-dreams.de>

2014-03-04spi: sun6i: Set bits_per_word_mask to only support 8 bits word lengthAxel Lin
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.

2014-02-16spi: sun6i: Fix define for SUN6I_TFR_CTL_CS_MASKAxel Lin
Current code in sun6i_spi_set_cs() actually clears CPHA and CPOL bits which is obvious wrong. The define for SUN6I_TFR_CTL_CS_MASK is wrong. Fix it.

2014-02-05spi: sunxi: Add Allwinner A31 SPI controller driverMaxime Ripard
The Allwinner A31 has a new SPI controller IP compared to the older Allwinner SoCs. It supports DMA, but the driver only does PIO for now, and DMA will be supported eventually. Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com> Signed-off-by: Mark Brown <broonie@linaro.org>
