Merge tag 'spi-nor/for-5.19' into mtd/next
SPI NOR core changes:
- Read back written SR value to make sure the write was done correctly.
- Introduce a common function for Read ID that manufacturer drivers can
use to verify the Octal DTR switch worked correctly.
- Add helpers for read/write any register commands so manufacturer
drivers don't open code it every time.
- Clarify rdsr dummy cycles documentation.
- Add debugfs entry to expose internal flash parameters and state.
SPI NOR manufacturer drivers changes:
- Add support for Winbond W25Q512NW-IM, and Eon EN25QH256A.
- Move spi_nor_write_ear() to Winbond module since only Winbond flashes
use it.
- Rework Micron and Cypress Octal DTR enable methods to improve
readability.
- Use the common Read ID function to verify switch to Octal DTR mode for
Micron and Cypress flashes.
- Skip polling status on volatile register writes for Micron and Cypress
flashes since the operation is instant.
