Winbond W35N01JW is SPI NAND flash supporting Octal DTR SPI protocol.

                       a
Add op_vairants for W35N01JW, which include the Octal DTR read/write

variants
page ops as well. Add W35N01JW's oob layout functions for the

                                     OOB

Okay, will correct these.

mtd_ooblayout_ops. Add all op adjustments required for Octal DTR SPI
mode using the adjust_op(). Finally, add an entry for W35N01JW in
spinand_info table.

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

Maybe we can split this into two parts:
1/ support the chip
2/ add 8-D support

I can split the patch into:
1/ Add implementation of manufacturer_ops: adjust_op() to handle variations of ops in 8D-8D-8D mode
2/ Add support/entry for Winbond W35N01JW SPI NAND flash chip

As 8-D support has already been added in a previous patch.

I also don't want the renaming to happen in the patch adding more
logic.


Okay, got it. Will amend this.

Thanks,
