The original OMAP4 hwmod data files is fully generated from HW
database. But since the file is introduced incrementaly along
with driver that uses the data, it has to be splitted by the driver
owner and then re-merged by the maintainer.
Because of the similarity of the data, git is completely lost
during such merge and thus the data does not look like the original one
at the end.
Re-order properly the structures to stay in sync with original data set.
This makes it much easier to diff the autogenerated script output with
what's in mainline, see differences, and generate patches for those
diffs. The goal is to stay in sync with the autogenerated data from now
on.
Add a comment that does contain all the IPs that can have a hwmod, but
do not have it in the file for the moment. It gives a good indication

OMAP4430_PRM_*_MOD macros have been moved into the prm44xx.h header.

The OMAP watchdog timer IP blocks require a specific set of register
writes to occur before they will be disabled[1], even if the device
clocks appear to be disabled in the CM_*CLKEN registers. In the MPU
watchdog case, failure to execute this reset sequence will eventually
cause the watchdog to reset the OMAP unexpectedly.
Previously, the code to disable this watchdog was manually called from
mach-omap2/devices.c during device initialization. This causes the
watchdog to be unconditionally disabled for a portion of kernel
initialization. This should be controllable by the board-*.c files,
since some system integrators will want full watchdog coverage of
kernel initialization. Also, the watchdog disable code was not
connected to the hwmod shutdown code. This means that calling
omap_hwmod_shutdown() will not, in fact, disable the watchdog, and the
goal of omap_hwmod_shutdown() is to be able to shutdown any on-chip
OMAP device.
To resolve the latter problem, populate the pre_shutdown pointer in
the watchdog timer hwmod classes with a function that executes the
watchdog shutdown sequence. This allows the hwmod code to fully
disable the watchdog.
Then, to allow some board files to support watchdog coverage
throughout kernel initialization, add common code to mach-omap2/io.c
to cause the MPU watchdog to be disabled on boot unless a board file
specifically requests it to remain enabled. Board files can do this
by changing the watchdog timer hwmod's postsetup state between the
omap2_init_common_infrastructure() and omap2_init_common_devices()
function calls.
