[PATCH v8 0/2] Add spi-nor flash device pm support

[Kamal Dasu]

Changes since v7 

spi-nor.h
- Fix comment style

spi-nor.c
- Fix condition check to set_4byte() when nor->addr_width == 4 in spi_nor_init()
- Bring back quad_enable logic to spi_nor_setup() and remove it from spi_nor_scan()
- Remove duplicate comment section in spi_nor_scan()
- Leave dev_info() string as before in spi_nor_scan()

The V8 changes below implements power management support using the mtd
handlers for resume in the spi-nor driver. spi-nor mtd pm resume() calls
newly implemented spi_nor_init() function that sets up the spi-nor flash
to its pre-suspend/power-on probed state. This is needed S2/S3 PM 
on platfroms that turn off power to the spi-nor flash on pm suspend.

Kamal Dasu (2):
  mtd: spi-nor: add spi_nor_init() function
  mtd: spi-nor: Add spi-nor mtd resume handler
