Start cleaning up the voltage layer to have a voltage domain layer
that resembles the structure of the existing clock and power domain
layers. To that end:
- move the 'struct voltagedomain' out of 'struct omap_vdd_info' to
become the primary data structure.
- convert any functions taking a pointer to struct omap_vdd_info into
functions taking a struct voltagedomain pointer.
- convert the register & initialize of voltage domains to look like
that of powerdomains
- convert omap_voltage_domain_lookup() to voltdm_lookup(), modeled
after the current powerdomain and clockdomain lookup functions.
- omap_voltage_late_init(): only configure VDD info when
the vdd_info struct is non-NULL

Eliminate need for global variables for the various PRM module offsets by
making them part of the VP/VC common structures
Eventually, these will likely be moved again, or more likely removed
when VP/VC code is isolated, but for now just getting rid of them as

In preparation for OMAP_CHIP() removal, split pwrdm_init() into three
functions. This allows some of them to be called multiple times: for
example, pwrdm_register_pwrdms() can be called once to register
powerdomains that are common to a group of SoCs, and once to register
powerdomains that are specific to a single SoC.
The appropriate order to call these functions - which is enforced
by the code - is:
1. pwrdm_register_platform_funcs()
2. pwrdm_register_pwrdms() (can be called multiple times)
3. pwrdm_complete_init()
Convert the OMAP2, 3, and 4 powerdomain init code to use these new
functions.
While here, improve documentation, and increase CodingStyle
conformance by shortening some local variable names.

After commit 665d001338 ("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
665d001338 ("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.

from hitting low power states (if bootloader has target states set to

omap_sr_disable_reset_volt is called with irqs off in omapx_enter_sleep,
as part of idle sequence, this eventually calls sr_disable and
pm_runtime_put_sync. pm_runtime_put_sync calls rpm_idle, which will
enable interrupts in order to call the callback. In this short interval
when interrupts are enabled, scenarios such as the following can occur:
while interrupts are enabled, the timer interrupt that is supposed to
wake the device out of idle occurs and is acked, so when the CPU finally
goes to off, the timer is already gone, missing a wakeup event.
Further, as the documentation for runtime states:"
However, subsystems can use the pm_runtime_irq_safe() helper function
to tell the PM core that a device's ->runtime_suspend() and ->runtime_resume()
callbacks should be invoked in atomic context with interrupts disabled
(->runtime_idle() is still invoked the default way)."
Hence, replace pm_runtime_put_sync with pm_runtime_put_sync_suspend
to invoke the suspend handler and shut off the fclk for SmartReflex
module instead of using the idle handler in interrupt disabled context.

SmartReflex should be disabled while entering low power mode due to
a) SmartReflex values are not defined for retention voltage, further
b) with SmartReflex enabled, if CPU enters lower c-states, FSM will try
to bump the voltage to current OPP's voltage for which it has entered c-state;
hence SmartReflex needs to be disabled for MPU, CORE and IVA voltage
domains in idle path before enabling auto retention voltage achievement
on the device.
However, since the current pm_runtime setup for SmartReflex devices are
setup to allow callbacks to be invoked with interrupts enabled, calling
SmartReflex enable/disable from other contexts such as idle paths
where preemption is disabled causes warnings such as the following
indicating of a potential race.

Fix up trivial conflict in arch/arm/mach-imx/mach-scb9328.c
Initialize get_context_loss_count in the DSS board data to
omap_pm_get_dev_context_loss_count, so that omapdss driver can use it.
Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
The function to get device's context loss count has changed from
omap_pm_get_last_off_on_transaction_id() to
omap_pm_get_dev_context_loss_count()
Change name of the function pointer in omapdss.h accordingly, and use
the term "context loss count" instead of "context id" in the code.
Restructure the context loss count functions to handle errors properly,
and ensure that context is always considered lost if an error happens.
