Cover letter [PATCH v4 0/1] Put the OMAP2 SPI CS in inactive state when returning from suspend
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 v3:
Patch clean-up according to Kevin Hilman and checkpatch.
Now force CS to be in inactive state only if it was inactive when it was suspended.
