* spi: spi-davinci: Add support for SPI_CS_WORDDavid Lechner2018-09-171-3/+8
| | | | | | | | | This adds support for the SPI_CS_WORD flag to the TI DaVinci SPI driver. This mode can be used as long as we are using the hardware chip select and not a GPIO chip select. Signed-off-by: David Lechner <david@lechnology.com> Signed-off-by: Mark Brown <broonie@kernel.org>
* Merge tag 'spi-cs-word' into spi-4.20Mark Brown2018-09-172-2/+31
|\ | | | | | | | | | | | | spi: Provide SPI_CS_WORD This provides a SPI operation mode which changes chip select after every word, used by some devices such as ADCs and DACs.
| * spi: add software implementation for SPI_CS_WORDDavid Lechner2018-09-171-1/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds a default software implementation for the SPI_CS_WORD flag for controllers that don't have such a feature. The SPI_CS_WORD flag indicates that the CS line should be toggled between each word sent, not just between each transfer. The implementation works by using existing functions to split transfers into one-word-sized transfers and sets the cs_change bit for each of the new transfers.

* | spi: davinci: Remove chip select GPIO pdataLinus Walleij2018-09-112-11/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The DaVinci SPI can use either: - Internal chip selects (inside the SPI host) - External chip selects (using GPIO) - External chip selects passed in pdata The last way of passing external chip selects through platform data is not used in the kernel. Delete it to make the code simpler when refactoring GPIO.

* | spi: gpio: No MISO does not imply no RXLinus Walleij2018-09-101-4/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is a logical problem in spi-gpio with host just assigning a MOSI line and no MISO: this is interpreted as the host cannot do RX and the host is flagged with SPI_MASTER_NO_RX. This is wrong: since GPIO lines can switch direction, in 3WIRE operation the host will simply reverse the direction of the GPIO line and start reading from it, there is even code for doing this in the driver, but it went unnoticed because it was tested by using a master with 4 wires but a device using just 3 wires. Remove the offending flag.

Christoph Hellwig suggested a rename of the associated types and interfaces to avoid the confusing usage of the 'compat' prefix for 32-bit architectures. To prepare for doing that in linux-4.20, add a set of macros that allows to convert subsystems separately to the new names and avoids some of the nastier merge conflicts.
