Subject: [PATCH v4 0/2] mtd: rawnand: Add support for manufacturer specific suspend/resume operation

Hi,

Changelog

v4:
Patch nand_suspend() return error code to the upper layer,
removed _ prefix of suspend/resme hooks and kbuildtest robot tag.

v3:
patch nand_lock_area/nand_unlock_area.
fixed kbuidtest robot warnings and reviewer's comments as below:
- Patched the Kdoc for both lock_area/unlock_area and _suspend/_resume
- Created a helper to read default protected value (after device power on)
  for protection function detection.
- patched the prefix for Macronix deep power down command, 0xB9
- Patched the description of mxic_nand_resume() and add a small sleeping 
  delay.
- Created a helper for deep power down device part number detection.

v2:
Patch nand_lock() & nand_unlock() for MTD->_lock/_unlock default call-back
function replacement. 
Patch nand_suspend() & nand_resume() with manufacturer specific operation.

v1:
Patch manufacturer post_init for MTD->_lock/_unlock & MTD->_suspend/_resume
replacement.

thanks for your time & review.
Mason
