2015-04-28dm: sf: Make SST flash write op work againBin Meng
With SPI flash moving to driver model, commit fbb0991 "dm: Convert spi_flash_probe() and 'sf probe' to use driver model" ignored the SST flash-specific write op (byte program & word program), which actually broke the SST flash from wroking. This commit makes SST flash work again under driver model, by adding SST flash-specific handling in the spi_flash_std_write().

2015-04-22mtd: spi: check return value of spi_setup_slavePeng Fan
Need to check value of spi_setup_slave and spi_setup_slave_fdt. If their return value 'bus' is NULL, there is no need to pass it to following spi_flash_probe_tail. If 'bus' is null, the original function flow is as following: spi_flash_probe |->spi_setup_slave |->spi_probe_bus_tail |->spi_flash_probe_slave |->spi_free_slave Alougth check the pointer in spi_free_slave is ok, checking the return value of spi_setup_slave and spi_setup_slave_fdt is better.

2015-04-18dm: spi_flash: fix wrong dependencyMasahiro Yamada
CONFIG_SPI does not exist in Kconfig in the first place, so the dependency "depends on DM && SPI" is never met, i.e., DM_SPI_FLASH can never be enabled (unless you ignore the dependency in an illegal way. See below.) Actually, some defconfigs such as socfpga_*_defconfig define CONFIG_DM_SPI_FLASH=y, but it never appears in the .config file because of this wrong dependency. On the other hand, all the Tegra boards enable DM_SPI_FLASH because config DM_SPI_FLASH default y silently ignores the dependency. Unfortunately, this style of CONFIG definition is abused everywhere in U-Boot, so we easily miss such a wrong dependency.

2015-01-30dm: spi: Move slave details to child platdataSimon Glass
At present we go through various contortions to store the SPI slave's chip select in its private data. This only exists when the slave is active so must be set up when it is probed. Until the device is probed we don't actually know what chip select it will appear on. However, now that we can support per-child platform data, we can use that instead. This allows us to set up the chip select when the child is bound, and avoid the messy contortions. Unfortunately this is a fairly large change and it seems to be difficult to break it down further.

2014-10-22dm: Convert spi_flash_probe() and 'sf probe' to use driver modelSimon Glass
We want the SPI flash probing feature to operate as a standard driver. Add a driver for the basic probing feature used by most boards. This will be activated by device_probe() as with any other driver. The 'sf probe' command currently keeps track of the SPI slave that it last used. This doesn't work with driver model, since some other driver or system may have probed the device and have access to it too. On the other hand, if we try to probe a device twice the second probe is a nop with driver model. Fix this by searching for the matching device, removing it, and then probing it again. This should work as expected regardless of other device activity. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Jagannadha Sutradharudu Teki <jagannadh.teki@gmail.com>
