Merge tag 'omap-cleanup-sparseirq-for-v3.7' into devel-dt

This branch contains changes needed to make omap2+
work properly with sparse IRQ. It also removes
dependencies to mach/hardware.h. These help moving
things towards ARM single zImage support.

This branch is based on a commit in tty-next
branch with omap-devel-gpmc-fixed-for-v3.7 and
cleanup-omap-tags-for-v3.7 merged in to keep things
compiling and sort out some merge conflicts.

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.

ARM: OMAP: omap_device: Do not overwrite resources allocated by OF layer

With the new devices (like, AM33XX and OMAP5) we now only support
DT boot mode of operation and now it is the time to start killing
slowly the dependency on hwmod, so with this patch, we are starting
with device resources.
The idea here is implemented considering to both boot modes -
  - DT boot mode
    OF framework will construct the resource structure (currently
    does for MEM & IRQ resource) and we should respect/use these
    resources, killing hwmod dependency.
    If pdev->num_resources > 0, we assume that MEM & IRQ resources
    have been allocated by OF layer already (through DTB).

    Once DMA resource is available from OF layer, we should
    kill filling any resources from hwmod.

  - Non-DT boot mode
    Here, pdev->num_resources = 0, and we should get all the
    resources from hwmod (following existing steps)

12 years agoserial: omap: drop "inline" from IRQ handler prototype

serial: omap: drop "inline" from IRQ handler prototype

it makes no sense to mark our IRQ handler inline
since it's passed as a function pointer when
enabling the IRQ line.

Two functions:
omap_serial_fill_features_erratas() and
of_get_uart_port_info() are only called from probe().
Marking them as __devinit gives us another
oportunity to free some code after .init.text

12 years agoserial: omap: don't save IRQ flags on hardirq

serial: omap: don't save IRQ flags on hardirq

When we're running our hardirq handler, there's
not need to disable IRQs with spin_lock_irqsave()
because IRQs are already disabled. It also makes
no difference if we save or not IRQ flags.

Switch over to simple spin_lock/spin_unlock and
drop the "flags" variable.
