Hi,
This series proposes patches for adding the following functionality
in SPI NAND core:

- Octal DTR SPI (8D-8D-8D) mode support

- Winbond W35N01JW SPI NAND chip support

- Power-on-Reset instruction support

This series has been tested on TI J721e EVM with the Winbond W35N01JW
flash with following test utilities:

- nandtest
  Test log: https://textbin.net/raw/fhypoz63f9

- mtd_stresstest
  Test log: https://textbin.net/raw/0xqjmqntj7

- UBIFS LTP stress test (NAND_XL_STRESS_DD_RW_UBIFS).
  Test log: https://textbin.net/raw/pyokws7wku

Datasheet: https://www.winbond.com/export/sites/winbond/datasheet/W35N01JW_Datasheet_Brief.pdf

Apurva Nandan (13):
  spi: spi-mem: Add DTR templates for cmd, address, dummy and data phase
  mtd: spinand: Add enum spinand_proto to indicate current SPI IO mode
  mtd: spinand: Setup spi_mem_op for the SPI IO protocol using reg_proto
  mtd: spinand: Fix odd byte addr and data phase in read/write reg op
    and write VCR op for Octal DTR mode
  mtd: spinand: Add adjust_op() in manufacturer_ops to modify the ops
    for manufacturer specific changes
  mtd: spinand: Add macros for Octal DTR page read and write operations
  mtd: spinand: Allow enabling Octal DTR mode in the core
  mtd: spinand: Reject 8D-8D-8D op_templates if octal_dtr_enale() is
    missing in manufacturer_op
  mtd: spinand: Add support for write volatile configuration register op
  mtd: spinand: Add octal_dtr_enable() for Winbond manufacturer_ops
  mtd: spinand: Add support for Power-on-Reset (PoR) instruction
  mtd: spinand: Perform Power-on-Reset when runtime_pm suspend is issued
  mtd: spinand: Add support for Winbond W35N01JW SPI NAND flash
