[PATCH v5 3/3] ARM: OMAP2+: onenand: prepare for gpmc driver migration

From: tony@atomide.com (Tony Lindgren)

Also in: linux-omap

* Afzal Mohammed [off-list ref] [120626 23:53]:
Reorganize gpmc-onenand initialization so that changes
required for gpmc driver migration can be made smooth.

Ensuring sync read/write are disabled in onenand cannot
be expected to work properly unless GPMC is setup, this
has been removed.

Refactor set_async_mode & set_sync_mode functions to
separate out timing calculation & actual configuration
(GPMC & OneNAND side).
The last patch in this series causes onenand not to show
up on my n900. I believe the problem has been there earlier
too, but I just did not notice it.

Without the last patch in this series I get:

[    1.650207] OneNAND driver initializing
[    1.655487] omap2-onenand omap2-onenand: initializing on CS0, phys base 0x04000000, virtual base d0880000, freq 83 MHz
[    1.666931] OneNAND Manufacturer: Numonyx (0x20)
[    1.671905] Muxed OneNAND 256MB 1.8V 16-bit (0x40)
[    1.676971] OneNAND version = 0x0031
[    1.918762] Creating 6 MTD partitions on "omap2-onenand":

And with this patch applied I get:

[    1.634643] OneNAND driver initializing
[    1.640075] omap2-onenand omap2-onenand: initializing on CS0, phys base 0x04000000, virtual base d0880000, freq 54 MHz
[    1.651519] OneNAND Manufacturer: Unknown (0xa0)

Any ideas?
