Get parameters for standard commands and requirements for enabling Quad and Octal modes from dts uint8-arrays containing data read from SFDP tables for particular flash chips. Upstream PR #: 93093 Signed-off-by: Andrzej Głąbek <[email protected]>
- Use standard operation codes and parameters from SFDP for handling most of the used commands (except for read, write, and erase for now) - Use common functions for reading and writing of status registers and for enabling write operations - Switch IO mode in a common function that perfors a transfer and do it only when required for a given command Upstream PR #: 93093 Signed-off-by: Andrzej Głąbek <[email protected]>
… handling of OER Complete implementation of quad_enable_set() by adding support for all possible Quad Enable Requirements (QER) as specified by the SFDP JEDEC standard (JESD216). Add also corresponding octal_enable_set() to handle Octal Enable Requirements. Upstream PR #: 93093 Signed-off-by: Andrzej Głąbek <[email protected]>
Add implementation of the most common Soft Reset routine (sequence of reset enable instruction 0x66 and reset instruction 0x99). Upstream PR #: 93093 Signed-off-by: Andrzej Głąbek <[email protected]>
…ad disabling Using a GPIO reset for a flash chip that has a dual function pin (RESET# or SIO3) and is to be used in Quad mode is rather a bad idea and so is clearing of the Quad Enable bit at every initialization of the flash driver, since this bit is usually non-volatile, so such operation means unnecessary wearing of the flash chip. Soft Reset should be use instead in such case. Upstream PR #: 93093 Signed-off-by: Andrzej Głąbek <[email protected]>
