4621d5f8cb OMAP: adapt hsmmc to hwmod framework
OMAP2420 platform consists of mmc block as in omap1 and not the
hsmmc block as present in omap2430, omap3, omap4 platforms.
Removing all base address macro defines except keeping one for OMAP2420 and
adapting only hsmmc device registration and driver to hwmod framework.

Changes involves:
1) Remove controller reset in devices.c which is taken care of
   by hwmod framework.
2) Using omap-device layer to register device and utilizing data from
   hwmod data file for base address, dma channel number, Irq_number,
   device attribute.
3) Update the driver to use dev_attr to find whether controller
   supports dual volt cards

e08016d0f4 omap: mmc: split out init for 2420
The MMC controller on the OMAP2420 is different from those
on the OMAP2430, OMAP3 and OMAP4 families - all of the latter
are identical. The one on the OMAP2420 is closer to that
on OMAP1 chips.

Currently, the n8x0 is the only OMAP2420 platform supported
in mainline which registers the MMC controller. Upcoming
changes to register the controllers using hwmod data are
potentially invasive. To reduce the risk, separate out the
2420 controller registration from the common init function
and update its only user. Also seperating out mux settings
for OMAP2420.

38698bef54 OMAP2+: clockevent: set up GPTIMER clockevent hwmod right before timer init
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

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>

The principle behind this patch, and some similar patches, is that the

Later in the boot process, the PM code, if compiled in with CONFIG_PM,
enables or re-enables power management features.

b80b956dc5 OMAP2+: clock: autoidle as many clocks as possible if CONFIG_OMAP_RESET_CLOCKS
Attempt to enable autoidle for as many clocks as possible in the
OMAP2+-common CONFIG_OMAP_RESET_CLOCKS code.  Currently, this only
enables DPLL autoidle for OMAP3/4 DPLLs; but future patches will
enable autoidle for other clocks and the OMAP2 DPLL/APLLs.

In the long run, we should probably get rid of
CONFIG_OMAP_RESET_CLOCKS, and unconditionally run the code that it
selects.  Otherwise, the state of the clock tree won't match the
hardware state - this could result in clocks being enabled or disabled
unpredictably.

Based on a patch by Rajendra Nayak <rnayak@ti.com> that did this in
the pm34xx.c/pm44xx.c code.

6c6f5a7437 OMAP3/4: DPLL: Add allow_idle/deny_idle support for all DPLL's
All OMAP3/4 dpll's support hardware level autogating.
Populate allow_idle/deny_idle function pointers for all
DPLL's in clkops.

5a2926b880 omap3: dpll: Populate clkops for dpll1_ck
DPLL1 on omap3 is very similar to the rest of
the non-core dpll's.
Hence populate clkops_omap3_noncore_dpll_ops
as the clkops for it, instead of the
currently populated clkops_null.

5f8662ba3d OMAP4: clockdomain: Remove pr_errs' stating unsupported wkdep
Now that wkup and sleep dependencies are supported (in the
form of static deps) for OMAP4, remove all instances of
pr_errs' stating dependencies are still unsupported
on OMAP4.

514c5948b2 OMAP4: clockdomain: Add clkdm static dependency srcs
OMAP4 supports static dependencies and dynamic dependencies
between clock domains. Static dependencies imply both
wakeup as well as sleep dependencies.
Generate all clockdomain static dependency sources.
(Dynamic dependency sources are hardwired and
cannot to controlled from software).

The autogen scripts are updated to generate the contents
of this patch.

4da71ae607 OMAP: clockdomain: Arch specific funcs for clkdm_clk_enable/disable
Define the following architecture specific funtions for omap2/3/4
.clkdm_clk_enable
.clkdm_clk_disable

Convert the platform-independent framework to call these functions.
Also rename the api's by removing the omap2_ preamble.
Hence call omap2_clkdm_k_enable as clkdm_clk_enable and
omap2_clkdm_clk_disable as clkdm_clk_disable.a

Remove unused functions (_enable/_disable_hwsup) and unsed
headers from clockdomain.c file.
