mtd: spi-nor: core: perform a Soft Reset on shutdown

2020-11-09T06:26:17Z

Perform a Soft Reset on shutdown on flashes that support it so that the flash can be reset to its initial state and any configurations made by spi-nor (given that they're only done in volatile registers) will be reset. This will hand back the flash in pristine state for any further operations on it.

mtd: spi-nor: add support for DTR protocol

2020-11-09T06:26:16Z

Double Transfer Rate (DTR) is SPI protocol in which data is transferred on each clock edge as opposed to on each clock cycle. Make framework-level changes to allow supporting flashes in DTR mode. Right now, mixed DTR modes are not supported. So, for example a mode like 4S-4D-4D will not work. All phases need to be either DTR or STR. The xSPI spec says that "The program commands provide SPI backward compatible commands for programming data...". So 8D-8D-8D page program opcodes are populated with using 1S-1S-1S opcodes.

mtd: spi-nor: fix kernel-doc for spi_nor::spimem

2020-04-28T06:55:50Z

When adding the 'spimem' field to 'struct spi_nor', a grammar mistake ("point" instead of "pointer") was made -- fix it and convert the SPI acronym to uppercase and fully spell out "memory", while at it...
