spi: spi-mem: Constify spi_mem->name

2018-08-03T09:51:25Z

There is no reason to make spi_mem->name modifiable. Moreover, spi_mem_ops->get_name() returns a const char *, which generates a gcc warning when assigning the value returned by spi_mem_ops->get_name() to spi_mem->name.

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: 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: spi-bitbang: change flags from u8 to u16

2018-07-18T14:54:21Z

This changes the data type of the flags field in struct spi_bitbang from u8 to u16. This matches the size of the mode field of struct spi_device where these flags are also used. This is done in preparation of adding a new SPI mode flag that will be used with this field that would otherwise not fit in 8 bits. Signed-off-by: David Lechner Signed-off-by: Mark Brown

mtd: nand: Add core infrastructure to support SPI NANDs

spi: Get rid of the spi_flash_read() API

2018-05-11T02:34:41Z

This API has been replaced by the spi_mem_xx() one, its only user (spi-nor) has been converted to spi_mem_xx() and all SPI controller drivers that were implementing the ->spi_flash_xxx() hooks are also implementing the spi_mem ones. So we can safely get rid of this API. Signed-off-by: Boris Brezillon Reviewed-by: Frieder Schrempf Tested-by: Frieder Schrempf Signed-off-by: Mark Brown
