7ecc5373fe OMAP4: hwmod data: Remove un-needed parens
A couple of parens were added around some flags.

Remove them, since they are not needed and not used
for any other hwmods.

9b4021befe OMAP4: hwmod data: Fix L3 interconnect data order and alignement
Change the position of the ocp_if structure to match the template.

Remove unneeded comma at the end of address space flag field.

Remove USER_SDMA since this ocp link is only from the l3_main_1
path that is accessible only from the MPU in that case and not
the SDMA.

bc6149587b omap_hwmod: use a terminator record with omap_hwmod_dma_info arrays
Previously, struct omap_hwmod_dma_info arrays were unterminated; and
users of these arrays used the ARRAY_SIZE() macro to determine the
length of the array.  However, ARRAY_SIZE() only works when the array
is in the same scope as the macro user.

So far this hasn't been a problem.  However, to reduce duplicated
data, a subsequent patch will move common data to a separate, shared
file.  When this is done, ARRAY_SIZE() will no longer be usable.

This patch removes ARRAY_SIZE() usage for struct omap_hwmod_dma_info
arrays and uses a sentinel value (irq == -1) as the array terminator
instead.

7a559c7882 omap: cleanup NAND platform data
omap_nand_platform_data fields 'options', 'gpio_irq', 'nand_setup' and
'dma_channel' are never referenced by the NAND driver, yet various
board files are initializing those fields. This is both incorrect and
confusing, so remove them. This allows to get rid of a global
variable in gpmc-nand.c.

This also corrects an issue where some boards are trying to pass NAND
16bit flag through .options, but the driver is using .devsize instead
and ignoring .options.

Finally, .dev_ready is treated as a flag by the driver, so make it bool
instead of a function pointer.

e74984e46e omap: Set separate timer init functions to avoid cpu_is_omap tests
This is needed for the following patches so we can initialize the

As with the init_irq calls, there's no need to do cpu_is_omap calls
during the timer init as we only care about the major omap generation.
This means that we can initialize the sys_timer with the .timer
entries alone.

Note that for now we just set stubs for the various sys_timer entries
that will get populated in a later patch. The following patches will
also remove the omap_dm_timer_init calls and change the init for the
