Tony Lindgren ca662ee7b8 ARM: OMAP2+: Remove unused ti81xx platform init code
The support for 81xx was never working in mainline, and the broken
legacy booting support has been removed. There are patches coming
to make 81xx boot with device tree, and for that we won't need any
of this legacy platform code, so let's just remove it.

Daniel Mack 386d20ab9e ARM: OMAP2: fix musb usage for n8x0
Commit b7e2e75a8c ("usb: gadget: drop unused USB_GADGET_MUSB_HDRC")
dropped a config symbol that was unused by the musb core, but it turns
out that board support code still had references to it.

As the core now handles both dual role and host-only modes, we can just
pass MUSB_OTG as mode from board files.

Remove now-obsolete code from arch/arm/mach-omap2/omap_device.c.  This
mostly consists of removing the first attempt at device PM latency

dev_pm_qos code, and needs to go away as part of the DT conversion.
Also, the early platform_device creation code has been removed, as it
appears to be unused.

We want to remove plat/cpu.h. To do this, let's first split

Tony Lindgren dbc0416104 ARM: OMAP: Split plat/hardware.h, use local soc.h for omap2+
As the plat and mach includes need to disappear for single zImage work,
we need to remove plat/hardware.h.

Do this by splitting plat/hardware.h into omap1 and omap2+ specific files.

The old plat/hardware.h already has omap1 only defines, so it gets moved
to mach/hardware.h for omap1. For omap2+, we use the local soc.h
that for now just includes the related SoC headers to keep this patch more
readable.

Note that the local soc.h still includes plat/cpu.h that can be dealt
with in later patches. Let's also include plat/serial.h from common.h for
all the board-*.c files. This allows making the include files local later
on without patching these files again.

Note that only minimal changes are done in this patch for the
drivers/watchdog/omap_wdt.c driver to keep things compiling. Further
patches are needed to eventually remove cpu_is_omap usage in the drivers.

Also only minimal changes are done to sound/soc/omap/* to remove the
unneeded includes and to define OMAP44XX_MCPDM_L3_BASE locally so there's
no need to include omap44xx.h.

While at it, also sort some of the includes in the standard way.

Tony Lindgren 7d7e1eba7e ARM: OMAP2+: Prepare for irqs.h removal
As the interrupts should only be defined in the platform_data, and
eventually coming from device tree, there's no need to define them
in header files.

Let's remove the hardcoded references to irqs.h and fix up the includes
so we don't rely on headers included in irqs.h. Note that we're
defining OMAP_INTC_START as 0 to the interrupts. This will be needed
when we enable SPARSE_IRQ. For some drivers we need to add
#include <plat/cpu.h> for now until these drivers are fixed to
remove cpu_is_omapxxxx() usage.

While at it, sort som of the includes the standard way, and add
the trailing commas where they are missing in the related data
structures.

Note that for drivers/staging/tidspbridge we just define things
locally.

Tony Lindgren 310018d52e ARM: OMAP2+: Fix MUSB ifdefs for platform init code
Commit 62285963 (usb: musb: drop a gigantic amount of ifdeferry)
got rid of a bunch of ifdefs in the MUSB code. Looks like the
platform init code is still using these dropped defines though,
which in many cases results the board defaulting always to host
mode.

Currently the situation is that USB_MUSB_HDRC is the main
Kconfig option with additional USB_GADGET_MUSB_HDRC so only
these two should be used to select between host and OTG mode.

Fix the situation for omaps. The following users should fix the
platform init code in a similar way:

Dropped Kconfig option          Current users

USB_MUSB_OTG                    blackfin, davinci, not in Kconfigs
USB_MUSB_PERIPHERAL             davinci, not in Kconfigs

Kevin Hilman 68a88b9887 ARM: OMAP: AM35xx: convert 3517 detection/flags to AM35xx
Currently cpu_is_omap3517() actually detects any device in the AM35x
family (3517 and no-SGX version 3505.)  To make it more clear what is
being detected, convert the names from 3517 to AM35xx.

This adds a new soc_is_am35xx() which duplicates the cpu_is_omap3517().
In order to avoid cross-tree dependencies with clock-tree changes,
cpu_is_omap3517() is left until the clock changes are merged,
at which point cpu_is_omap3517() will be completely removed.

Kevin Hilman 3410773013 ARM: OMAP: AM35xx: remove redunant cpu_is checks for AM3505
There are several checks for AM35x devices done using

      if (cpu_is_omap3517() || cpu_is_omap3505())

However, since the 3505 is just a 3517 without an SGX, the 3505 check
is redundant because cpu_is_omap3517() will always be true whenever
cpu_is_omap3505() is true.  From <plat/cpu.h>:

 #define cpu_is_omap3505() (cpu_is_omap3517() && !omap3_has_sgx())

Therefore, remove the redunant 3505 checks.  This helps move towards
removal of SoC detection that depends on specific IP detection.

Hema Kalliguddi fcf173e451 usb: musb: add names for IRQs in structure resource
Soon resource data will get automatically
populated from a set of autogenerated data
from TI's hardware database for the OMAP
platform.

Such database, might not have resources at
the expected order by the current drivers.

While we could hack in some exceptions to
that tool to generate resources in a specific
order, it seems less fragile to use the
resource name instead. That way, no matter
what order the resources are generated, the
driver still work.

Modified the OMAP, Blackfin and Davinci
architecture files to add the name of the IRQs
in the resource structures and musb driver to
use the platform_get_irq_byname() api to get
the device and dma irq numbers instead of using
the index.
