[PATCH v2 0/2] mtd: spi-nor: Avoid setting SRWD bit in SR

[Amit Kumar Mahapatra <amit.kumar-mahapatra@amd.com>]

Setting the status register write disable (SRWD) bit in the status
register (SR) with WP signal of the flash not connected will configure the
SR permanently as read-only. To avoid this a boolean type DT property
"broken-wp" is introduced. If this property is defined, the spi-nor doesn't
set the SRWD bit in SR while performing flash protection operation.

BRANCH: for-next

Changes in v2:
- Modified DT property description to add information about a
  valid use case.
- Added Reviewed-by tag in 1/2.
- Updated comment description in 2/2.
