Add support for triggering asynchronous events when a timestamp
expires. The infrastructure is generic enough to support different
sorts of events and callbacks. The first user of the event
infrastructure is a way to release a genlock locks on behalf of a
user space process.

Until now only the BMS system was using the ccadc so there was
no need to create a separate ccadc driver.
However we can run in a configuration with BMS disabled
and clients won't be able to read battery current via ccadc.
Separate the ccadc from the bms, this change in is preparation
to add a ccadc api to read the battery current.

Since the driver will be changing the max vdd if the battery
temperature enters warm or cool zone, it should also change
the vbatdet voltage so resume of charging can begin accordingly.
Also provide a means to quickly debug is the battery is in cool/warm

Current implementation supports PHY retention mode, when
VBUS detection is done by PMIC.
This change adds the support for PHY retention mode, for
the case where VBUS detection is done by USB PHY.
In that case, the PHY wakes up the MPM and CORE using its
High-Voltage interrupts.

Synopsis 28nm PHY has two different circuits for detecting changes on
ID line. ID_DIG is designed for detecting ID_float vs ID_gnd. ID_ACA
is designed for detecting RID_A, RID_B, RID_C states. These are mutually
exclusive and enabling both circuits has undefined behavior. Enable
ID_ACA upon VBUS high or ID_gnd events to detect further ACA states.
ACA ID_GND threshold range is overlapped with OTG ID_FLOAT threshold range.
Hence PHY ID_DIG circuit can not be used for detecting ACA ID_GND. Use
PMIC ID circuit for detecting both OTG and ACA ID_GND.
Link controller can not generate PHY_ALT interrupt in host mode. But the
corresponding PHY register reflects the actual ID state. Hence implement
polling to read PHY register to detect ID_GND --> ID_A, ID_A --> ID_B
transitions. That means low power mode can not be allowed in host mode.
Also disallow suspending the device attached on the root hub. Otherwise
PHY is put into suspend state automatically upon setting SUSP bit in PORTSC
register.
Link controller can not generate asynchronous interrupt for ID_ACA changes
in low power mode. Hence disallow low power mode in ID_B and ID_C states.
USB_MSM_ACA is not selected by default. If it selected, ACA states can be
detected and low power mode is not allowed in host mode. Writing "enable"
to <debugfs>/msm_otg/aca enables ACA irrespective of USB_MSM_ACA selection.
This is meant for debugging only.

Runtime PM is used to turn clocks on and off when the controller is
not in use. There are 2 use-cases for the controller:
When the controller is used for messaging, pm_runtime_get is called
before sending the message. pm_runtime_put is called when message is
sent and/or response is received.
When the controller is used for data channels, pm_runtime_get is
called when data channel slot usage goes from 0 to non-zero.
pm_runtime_put can't be just called when data channel is scheduled
since data channel activity is going on until the data channel is
explicitly taken down. In that case, pm_runtime_put is called when
data channels are no longer using any slots on the bus.
pm_runtime_autosuspend is used to ensure that runtime_suspend doesn't
happen right after runtime enters idle state. This serves 2 purposes:
1. Resources aren't turned on/off too frequently.
2. There is a use case from audio where it does read/write to some
registers and the following data-channel setup happens from the LPASS
(satellite side). The timer ensures that there is no runtime_suspend
between these 2 activities.

The current split between this and the fiq debugger is awkward and does
not have any benefit (the interface between the two is also too simplistic).
The fiq debugger code itself needs a lot of refactoring, part of which
would be to split out some components that are arch indpendent.
So, for now, move this very small piece back into the fiq_debugger.
