Merge tag 'omap-cleanup-b2-for-3.8' of git://git.kernel.org/pub/scm/linux/kernel/git/pjw/omap-pending into omap-for-v3.8/cleanup-prcm

Second set of OMAP PRCM cleanups for 3.8.

These patches remove the use of omap_prcm_get_reset_sources() from the
OMAP watchdog driver, and remove mach-omap2/prcm.c and
plat-omap/include/plat/prcm.h.

Basic test logs for this branch on top of Tony's cleanup-prcm branch
at commit 7fc54fd3 are here:

    http://www.pwsan.com/omap/testlogs/prcm_cleanup_b_3.8/20121108151646/

However, cleanup-prcm at 7fc54fd3 does not include some fixes
that are needed for a successful test.  With several reverts,
fixes, and workarounds applied, the following test logs were
obtained:

    http://www.pwsan.com/omap/testlogs/TEST_prcm_cleanup_b_3.8/20121108151930/

 which indicate that the series tests cleanly.

This second pull request updates one of the patches which broke
with rmk's allnoconfigs, and also updates the tag description to
indicate that 7fc54fd3 is building cleanly here.

The hwmod code unconditionally calls _omap4_disable_module() on all
SoCs when a module doesn't enable correctly.  This "worked" due to the
weak function omap4_cminst_wait_module_idle() in
arch/arm/mach-omap2/prcm.c, which was a no-op.  But now those weak
functions are going away - they should not be used.  So this patch
will now call the SoC-specific disable_module code, assuming it
exists.

Needs to be done before the weak function is removed, otherwise AM33xx
will crash early in boot.

Convert the OMAP clock code's _omap2_module_wait_ready() to use
SoC-independent CM functions that are provided by the CM code, rather
than using a deprecated function from mach-omap2/prcm.c.

This facilitates the future conversion of the CM code to a driver, and
also removes a mach-omap2/prcm.c user.  mach-omap2/prcm.c will be removed
by a subsequent patch.

Some modules have IDLEST registers that aren't in the CM module, such
as the AM3517 IDLEST bits.  So we also need a fallback function for
these non-CM odd cases.  Create a temporary one in mach-omap2/clock.c,
intended to exist until the SCM drivers are ready.

Convert the OMAP2xxx APLL code to use omap2_cm_wait_module_ready(),

on the deprecated omap2_cm_wait_idlest() function in
mach-omap2/prcm.c, so that code can be removed later; and move
low-level register accesses to the CM IP block to the CM code, which
will soon be moved into drivers/.

Split omap_prcm_restart() from mach-omap2/prcm.c into SoC-specific
variants.  These functions need to be able to save the reboot reason
into the scratchpad RAM.  This implies a dependency on both the PRM
and SCM IP blocks, so they've been moved into their own file.  This
will eventually call functions in the PRM and SCM drivers, once those
are created.

Vaibhav Hiremath <hvaibhav@ti.com> identified an unused prototype in
the first version of this patch - now removed.  Tony Lindgren
<tony@atomide.com> noted a compile problem with some RMK Kconfigs;

Previously the OMAP watchdog driver used a non-standard way to report
the chip reset source via the GETBOOTSTATUS ioctl.  This patch
converts the driver to use the standard WDIOF_* flags for this
purpose.

This patch may break existing userspace code that uses the existing
non-standard data format returned by the OMAP watchdog driver's
GETBOOTSTATUS ioctl.  To fetch detailed reset source information,
userspace code will need to retrieve it directly from the CGRM or PRM
drivers when those are completed.

Previously, to fetch the reset source, the driver either read a
register outside the watchdog IP block (OMAP1), or called a function
exported directly from arch/arm/mach-omap2.  Both approaches are
broken.  This patch also converts the driver to use a platform_data
function pointer.  This approach is temporary, and is due to the lack
of drivers for the OMAP16xx+ Clock Generation and Reset Management IP
block and the OMAP2+ Power and Reset Management IP block.  Once
drivers are available for those IP blocks, the watchdog driver can be
converted to call exported functions from those drivers directly.
At that point, the platform_data function pointer can be removed.

In the short term, this patch is needed to allow the PRM code to be
removed from arch/arm/mach-omap2 (it is being moved to a driver).
