Show all headers | View raw

Changes since v6 

spi-nor.h
- Reverted all v6 changes
- Added info pointer to spi-nor structure
- Added quad_enable function pointer

spi-nor.c
- Reverted all v6 changes
- Refactored spi_nor_init() function
- Added mtd resume handlers 

The V7 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
