mtd: sf: Drop plat from sf_probe

2020-06-01T12:25:24Z

dm_spi_slave_platdata used in sf_probe for printing plat->cs value and there is no relevant usage apart from this. We have enough debug messages available in SPI and SF areas so drop this plat get and associated bug statement. Cc: Simon Glass Cc: Vignesh R Signed-off-by: Jagan Teki

mtd: spi: Call sst_write in _write ops

2020-06-01T12:25:24Z

Currently spi-nor code is assigning _write ops for SST and other flashes separately. Just call the sst_write from generic write ops and return if SST flash found, this way it avoids the confusion of multiple write ops assignment during the scan and makes it more feasible for code readability. No functionality changes. Cc: Simon Glass Cc: Vignesh R Signed-off-by: Jagan Teki

sf: Drop spl_flash_get_sw_write_prot

2020-06-01T12:25:24Z

The get_sw_write_prot API is used to get the write-protected bits of flash by reading the status register and other wards it's API for reading register bits. 1) This kind of requirement can be achieved using existing flash operations and flash locking API calls instead of making a separate flash API. 2) Technically there is no real hardware user for this API to use in the source tree. 3) Having a flash operations API for simple register read bits also make difficult to extend the flash operations. 4) Instead of touching generic code, it is possible to have this functionality inside spinor operations in the form of flash hooks or fixups for associated flash chips. Considering all these points, this patch drops the get_sw_write_prot and associated code bases. Cc: Simon Glass Cc: Vignesh R Signed-off-by: Jagan Teki

On i.mx7ulp EVK board, we use MX25R6435F NOR flash, add its parameters and IDs to flash parameter array. Otherwise, the flash probe will fails. Signed-off-by: Ye Li Signed-off-by: Peng Fan

spi: fix dev parameter in dev_* calls

Probably the non-use of the device parameter by the print routines did not generate compilation errors. Signed-off-by: Dario Binacchi
