We notice that when system wake up from OFF mode, then CS is in inactive
state until the first SPI transfer.
For our design it lead to some conflict on this I/O.
Inactive state for CS when there is no transfer should be the correct
behavior: this is the purpose of these patches.
* Change from v1:
Rebase on linus/master (after 2.6.37-rc1)
Do some clean-up and fix indentation on both patches
Add more explanations for patch 2
Gregory CLEMENT (2):
spi: Add hook on suspend/resume for spi master
spi: Force CS to be in inactive state after off-mode transition
