      OMAP2/3: VENC hwmod: add OCPIF_SWSUP_IDLE flag to interface · c39bee8a
      由 Paul Walmsley 提交于 
      According to the hwmod interface data, the DSS submodule "VENC" uses a
clock, "dss_54m_fck"/"dss_tv_fck", which the PRCM cannot autoidle.  By
default, the hwmod code assumes that interface clocks can be autoidled
by the PRCM.  When the interface clock can't be autoidled by the PRCM,
those interfaces must be marked with the OCPIF_SWSUP_IDLE flag.
Otherwise, the "interface clock" will always have a non-zero use
count, and the device won't enter idle.  This problem was observed on
N8x0.

Fix the immediate problem by marking the VENC interface with the
OCPIF_SWSUP_IDLE flag.  But it's not clear that
"dss_54m_fck"/"dss_tv_fck" is really the correct interface clock for
VENC.  It may be that the VENC interface should use a
hardware-autoidling interface clock.  This is the situation on OMAP4,
which uses "l3_div_ck" as the VENC interface clock, which can be
autoidled by the PRCM.  Clarification from TI is needed.

      OMAP2+: sdrc: fix compile break on OMAP4-only config on current omap-for-linus · d6b5d01b
      由 Paul Walmsley 提交于 
      On non-OMAP2 and non-OMAP3 kernel configs, turn omap2_sdrc_init() into
a no-op.  Otherwise, compilation breaks on an OMAP4-only config with
the current omap-for-linus branch:

arch/arm/mach-omap2/built-in.o: In function `omap2_init_common_devices':
../mach-omap2/io.c:421: undefined reference to `omap2_sdrc_init'

Thanks to Sergei Shtylyov <sshtylyov@mvista.com> for suggesting the use
of a empty static inline function rather than a macro.

      OMAP2+: clockevent: set up GPTIMER clockevent hwmod right before timer init · 38698bef
      由 Paul Walmsley 提交于 
      Set up the GPTIMER hwmod used for the clockevent source immediately
before it is used.  This avoids the need to set up all of the hwmods
until the boot process is further along.  (In general, we want to defer
as much as possible until late in the boot process.)

This second version fixes a bug pointed out by Santosh Shilimkar
<santosh.shilimkar@ti.com>, that would cause the kernel to use an
incorrect timer hwmod name if the selected GPTIMER was not 1 or 12 -
thanks Santosh.  Also, Tarun Kanti DebBarma <tarun.kanti@ti.com>
pointed out that the original patch did not apply cleanly; this has
now been fixed.

      OMAP2+: hwmod: add ability to setup individual hwmods · a2debdbd
      由 Paul Walmsley 提交于 
      Add omap_hwmod_setup_one(), which is intended for use early in boot to
selectively setup the hwmods needed for system clocksources and
clockevents, and any other hwmod that is needed in early boot.
omap_hwmod_setup_all() can then be called later in the boot process.
The point is to minimize the amount of code that needs to be run
early.

      OMAP2+: hwmod: ignore attempts to re-setup a hwmod · 48d54f3f
      由 Paul Walmsley 提交于 
      Previously, if a hwmod had already been set up, and the code attempted
to set up the hwmod again, an error would be returned.  This is not
really useful behavior if we wish to allow the OMAP core code to setup
the hwmods needed for the Linux clocksources and clockevents before
the rest of the hwmods are setup.  So, instead of generating errors,
just ignore the attempt to re-setup the hwmod.

      OMAP2+: hwmod: find MPU initiator hwmod during in _register() · 569edd70
      由 Paul Walmsley 提交于 
      Move the code that looks for the MPU initiator hwmod to run during
the individual hwmod _register() function.  (Previously, it ran after
all hwmods were registered in the omap_hwmod_late_init() function.)

This is done so code can late-initialize a few individual hwmods --
for example, for the system timer -- before the entire set of hwmods is
initialized later in boot via omap_hwmod_late_init().

      OMAP2+: hwmod: rename some init functions · 550c8092
      由 Paul Walmsley 提交于 
      Rename omap_hwmod_init() to omap_hwmod_register().  Rename
omap_hwmod_late_init() to omap_hwmod_setup_all().  Also change all of
the callers to reflect the new names.  While here, update some
copyrights.

Suggested by Tony Lindgren <tony@atomide.com>.

N.B. The comment in mach-omap2/serial.c may no longer be correct, given
     recent changes in init order.

      OMAP2+: hwmod: allow multiple calls to omap_hwmod_init() · bac1a0f0
      由 Paul Walmsley 提交于 
      There's no longer any reason why we should prevent multiple
calls to omap_hwmod_init().  It is now simply used to register an
array of hwmods.

This should allow a subset of hwmods (e.g., hwmods
handling the system clocksource and clockevents) to be registered
earlier than the remaining mass of hwmods.
