Subject: [PATCH 06/13] mtd: spinand: Add macros for Octal DTR page read and write operations
Date:   Tue, 13 Jul 2021 13:05:31 +0000

Define new PAGE_READ_FROM_CACHE and PROG_LOAD op templates for Octal
DTR SPI mode. These templates would used in op_variants and
op_templates for defining Octal DTR read from cache and write to
cache operations.
