After commit 665d0013 ("OMAP2+: hwmod:
Follow the recommended PRCM module enable sequence"), device drivers
for OMAP IP blocks that do not use runtime PM can cause oopses or
kernel instability[1][2].

This is because those non-runtime PM drivers do not use the hwmod
code, which implements the correct IP block enable and disable
sequence.

Several options for dealing with this problem have been proposed:

1. Add a new field to the OMAP struct clk to mark clocks that are
   currently used by non-runtime PM drivers.  Modify the clock code to
   use the old clockdomain sequence for these marked clocks.  As
   drivers are converted to use runtime PM, remove the annotation from
   the clocks.

2. Similar to #1, but associate the flag with the struct omap_clk
   instead.

3. Add IDLEST wait support to the OMAP4 clock code, similar to the way
   it is implemented for OMAP2/3, and enable it in each struct clk
   currently used by non-runtime PM drivers.  As drivers are converted
   to use runtime PM, remove the annotation from the clocks.

4. Do nothing; leave the problem to those responsible for the
   unconverted drivers.

5. Re-enable clock-based clockdomain control in the OMAP4 clock code.
   This would revert back to the behavior of Linux 3.0, simply with a
   slightly longer module enable/disable latency.

Unfortunately, no approach seemed particularly good.  Options 1
through 3 seemed unwise due to the following reasons:

A. The OMAP struct clks are intended primarily to describe hardware
   clock nodes, and the intention is that no driver-specific data
   should be stored there (applies to #1)

B. The resulting patch would have been quite large for the -rc series
   (applies to #1, #2, #3)

C. The patch would have been a new, yet temporary hack; and similar fixes
   have drawn negative comments in the recent past (see for example [3])

Option 4 is undesirable because commit
665d0013 ("OMAP2+: hwmod: Follow the
recommended PRCM module enable sequence") has resulted in a less
stable kernel; and kernel stability is more important than OMAP4 power
management.

Option 5 is the approach taken in this patch.  This seemed to be the
least intrusive approach for 3.1-rc.

The approach in this patch was originally proposed by Ohad Ben-Cohen
<ohad@wizery.com>.  I'm simply writing the commit message and passing
it along.

On OMAP4, the PRCM recommended sequence for enabling
a module after power-on-reset is:
-1- Force clkdm to SW_WKUP
-2- Enabling the clocks
-3- Configure desired module mode to "enable" or "auto"
-4- Wait for the desired module idle status to be FUNC
-5- Program clkdm in HW_AUTO(if supported)

This sequence applies to all older OMAPs' as well,
however since they use autodeps, it makes sure that
no clkdm is in IDLE, and hence not requiring a force
SW_WKUP when a module is being enabled.

OMAP4 does not need to support autodeps, because
of the dyanamic dependency feature, wherein
the HW takes care of waking up a clockdomain from
idle and hence the module, whenever an interconnect
access happens to the given module.

Implementing the sequence for OMAP4 requires
the clockdomain handling that is currently done in
clock framework to be done as part of hwmod framework
since the step -4- above to "Wait for the desired
module idle status to be FUNC" is done as part of
hwmod framework.

On OMAP4, CPU accesses on unmapped addresses are redirected to GPMC by
L3 interconnect. Because of CPU speculative nature, such accesses are
possible which can lead to indirect access to GPMC and if it's clock is
not running, it can result in hang/abort on the platform.

Above makes access to GPMC unpredictable during the execution, so it's
module mode needs to be kept under hardware control instead of software
control.
Since the auto gating is supported for GPMC, there isn't any power impact
because of this change.

The issue was un-covered with security middleware running along with HLOS.
In this case GPMC had a valid MMU descriptor on secure side where as HLOS
didn't map the GMPC because it isn't being used.

DSS driver has used fck and ick clocks on OMAP2/3 to get DSS HW up and
running, and also to get the pixel clock's source clock rate from the
fck.

On OMAP4 the clock data is set up in a different way, as there's no ick,
dss_fck points to a fake clock which just affects DSS's MODULEMODE, and
dss_dss_clk if the DSS_FCK.

>From DSS driver's point of view the dss_fck sounds like an ick, and
dss_dss_clk is the fck. While this is not entirely correct from HW point
of view, especially for the ick, configuring the clock aliases that way
makes DSS "just work" with OMAP4's clock setup.

In the (hopefully near) future DSS driver will be reworked to use
pm_runtime support which should clean up the clock code.

L3INSTR clock domain is read only register and its reset value is

MODULEMODE:
- 0x0: Module is disable by software. Any INTRCONN access to module
  results in an error, except if resulting from a module wakeup
  (asynchronous wakeup).
- 0x1: Module is managed automatically by hardware according to
  clock domain transition. A clock domain sleep transition put
  module into idle. A wakeup domain transition put it back
  into function. If CLKTRCTRL=3, any INTRCONN access to module
  is always granted. Module clocks may be gated according to
  the clock domain state.

This patch keeps CM_L3INSTR_L3_3_CLKCTRL, CM_L3INSTR_L3_INSTR_CLKCTRL
and CM_L3INSTR_INTRCONN_WP1_CLKCTRL module mode under hardware control
by using ENABLE_ON_INIT flag.

Without this the OMAP4 device OFF mode SAR restore phase aborts during
interconnect register restore phase. This can be also handled by doing
explicit a clock enable and disable in the low power code since there
is no direct module associated with it. But that seems not necessary
since the clock domain is under HW control.

J-Type DPLLs have additional configuration parameters that need to
be programmed when setting the multipler and divider for the DPLL.
These parameters being the sigma delta divider (SD_DIV) for the DPLL
and the digital controlled oscillator (DCO) to be used by the DPLL.

The current code is implemented specifically to configure the
OMAP3630 PER J-Type DPLL. The OMAP4430 USB DPLL is also a J-Type DPLL
and so this code needs to be updated to work for both OMAP3 and OMAP4
devices and any other future devices that have J-TYPE DPLLs.

For the OMAP3630 PER DPLL both the SD_DIV and DCO paramenters are
used but for the OMAP4430 USB DPLL only the SD_DIV field is used.
The current implementation will only program the SD_DIV and DCO
fields if the DPLL has both and hence this does not work for
OMAP4430.

In order to make the code more generic add two new fields to the
dpll_data structure for the SD_DIV field and DCO field bit-masks
and only program these fields if the masks are defined for a specific
DPLL. This simplifies the code and allows us to remove the flag
DPLL_NO_DCO_SEL.

This process also requires the #includes in each of these files to be

header file of the hardware module that they belong to.  For example,
OMAP4430_PRM_*_MOD macros have been moved into the prm44xx.h header.

Adjust #includes of all files that used the old PRCM header file names
to point to the new filenames.

The autogeneration scripts have been updated accordingly.

The convention for omap device naming is omap_XXX.

Rename the device and driver name in order to stick
to this naming convention.

Change device name in clock nodes as well.

musb core doesn't need to know about platform
specific details. So start moving clock
handling to platform glue layer and make
musb core agnostic about that.

change all ocurrences of musb_hdrc to musb-hdrc.

We will call glue layer drivers musb-<glue layer>,
so in order to keep things somewhat standard, let's
change the underscore into a dash.

Add clkdev aliases for the USBHOST and USBTLL clocks on OMAP3 and
OMAP4, so that the driver can refer to the clocks using a common alias.

This will disappear when the driver is converted to use the hwmod
database, but until then this patch is needed.

Only OMAP2+ platforms have the System Control Module (SCM) IP block.
In the past, we've kept the SCM header file in plat-omap.  This has
led to abuse - device drivers including it; includes being added that
create implicit dependencies on OMAP2+ builds; etc.

In response, move the SCM headers into mach-omap2/.

As part of this, remove the direct SCM access from the OMAP UDC
driver.  It was clearly broken.  The UDC code needs an indepth review for
use on OMAP2+ chips.
