*	spi: spi-mem: Extend the SPI mem interface to set a custom memory name	Frieder Schrempf	2018-08-02	1	-0/+28
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	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 <boris.brezillon@bootlin.com> Signed-off-by: Frieder Schrempf <frieder.schrempf@exceet.de> Reviewed-by: Boris Brezillon <boris.brezillon@bootlin.com> Signed-off-by: Mark Brown <broonie@kernel.org>
*	spi: Extend the core to ease integration of SPI memory controllers	Boris Brezillon	2018-05-11	1	-0/+410
	Some controllers are exposing high-level interfaces to access various kind of SPI memories. Unfortunately they do not fit in the current spi_controller model and usually have drivers placed in drivers/mtd/spi-nor which are only supporting SPI NORs and not SPI memories in general. This is an attempt at defining a SPI memory interface which works for all kinds of SPI memories (NORs, NANDs, SRAMs).
