spi: davinci: fix a NULL pointer dereference

2018-08-10T10:48:37Z

On non-OF systems spi->controlled_data may be NULL. This causes a NULL pointer derefence on dm365-evm. Signed-off-by: Bartosz Golaszewski Signed-off-by: Mark Brown Cc: stable@vger.kernel.org

spi: spi-mem: Extend the SPI mem interface to set a custom memory name

2018-08-02T14:35:41Z

When porting (Q)SPI controller drivers from the MTD layer to the SPI layer, the naming scheme for the memory devices changes. To be able to keep compatibility with the old drivers naming scheme, a name field is added to struct spi_mem and a hook is added to let controller drivers set a custom name for the memory device. Example for the FSL QSPI driver: Name with the old driver: 21e0000.qspi, or with multiple devices: 21e0000.qspi-0, 21e0000.qspi-1, ... Name with the new driver without spi_mem_get_name: spi4.0 Suggested-by: Boris Brezillon Signed-off-by: Frieder Schrempf Reviewed-by: Boris Brezillon Signed-off-by: Mark Brown

spi: uniphier: remove unnecessary include headers

spi: spi-gpio: add SPI_3WIRE support

2018-08-01T13:50:28Z

Add SPI_3WIRE support to spi-gpio controller introducing set_line_direction function pointer in spi_bitbang data structure. Spi-gpio controller has been tested using hts221 temp/rh iio sensor running in 3wire mode and lsm6dsm running in 4wire mode Signed-off-by: Lorenzo Bianconi Signed-off-by: Mark Brown

spi: add flags parameter to txrx_word function pointers

2018-08-01T13:50:24Z

Add the capability to specify the flag parameter used in bitbang_txrx_be_cpha{0,1} through the txrx_word function pointers of spi_bitbang data structure. That feature will be used to add spi-3wire support to the spi-gpio controller Signed-off-by: Lorenzo Bianconi Signed-off-by: Mark Brown

spi: add SPI controller driver for UniPhier SoC

2018-08-01T10:22:37Z

Add SPI controller driver implemented in Socionext UniPhier SoCs. UniPhier SoCs have two types SPI controllers; SCSSI supports a single channel, and MCSSI supports multiple channels. This driver supports SCSSI only. This controller has 32bit TX/RX FIFO with depth of eight entry, and supports the SPI master mode only. This commit is implemented in PIO transfer mode, not DMA transfer. Signed-off-by: Kunihiko Hayashi Signed-off-by: Keiji Hayashibara Reviewed-by: Andy Shevchenko Signed-off-by: Mark Brown

spi: img-spfi: Set device select bits for SPFI port state

2018-07-30T15:31:54Z

Even if the chip select line is not controlled by the SPFI hardware, the device select bits need to be set to specify the chip select line in use for the hardware to know what parameters to use for the current transfer.
