Currently there are no channel specific properties associated
with the RRADC channels. The existing channel nodes specify
a logical channel number that is used by the client when
requesting the RRADC channel read. This can instead be obtained
from the channel list specified within the driver. Therefore
remove the channel nodes.

A check is needed to ensure the LSB and MSB are coherent
when reading the result registers for the RRADC channels.
The driver performs another round of read request and
compares the result registers to ensure the data read
back is coherent.
Since there are no channel specific properties remove
the dependency to add the channel nodes in the device
tree and instead statically register the channels within
the driver.
Update the scaling functions to report in the units
desired for the final scaled value based on the channel.
The resistance channel reports the units for batt_id
in ohms, the voltage channels such as DCIN, USBIN report
the value in units of microvolts, the current channels
in units of microamps and the temperature channels
such as thermistors are reported in units of millidegC.

Change the default IPC logging messages to help log analysis instead of
having to change log mask levels and having to re-run the test cases.
Currently single log is used to gather all the driver messages. Split
these into dedicated tx/rx payload log, client ioctl/power state log and
generic driver state log.
Also only dump 32 bytes of the tx/rx payload.

Don't modify the ref count variable clk count inside the runtime callbacks.
Doing so could result in a case where the driver might end up calling a put
twice on the runtime object. The resulting imbalance will leave the runtime
state for the device in a bad state.

As part of the resource voting, both the resource_vote and unvote
functions call the toggle_wakeup_interrupt() function which toggles the
state of the wakeup irq unconditionally. This can cause issues in adverse
scenarios. Instead split this out into exclusive enable and disable wakeup
interrupt functions to be called during the resource unvote and vote
respectively. Also don't make resource votes in the wakeup isr, the
wakeup isr injects a pre-determined byte into the tty flip buffer and
doesn't access the core or setup any transactions and hence doesn't need
to vote for resources.
The driver has registered for the noirq system suspend/resume callbacks.
When executing these callbacks, don't rely on the runtime framework to
check the device's current runtime state before deciding whether to allow
system suspend or not as the runtime framework is disabled at this point.
Instead rely on the power state that the driver maintains internally.

For USB 2.0 there is a requirement to not to flush the
USB endpoints after the pipes are disconnected. Otherwise
this can result into NOC errors. Make a change to modify the
disconnect sequence as below.
1) USB driver first disable the pipes
2) New API is provided from IPA to disable the endpoint.
3) As part of disable, make sure pipes are empty and reset
the pipes.
4) USB resets its BAM and flushes the ep.
5) USB then disconnects both IPA and USB pipes.

During IPA driver processing context delete, a delete to
the referenced header is being done. The header deletion
will also commit the changes to H/W which includes the
processing context commit. This resulted into committing
an invalid process context as it is still in the processing
context list, but points to deleted header.
The fix is to not commit the changes when deleting the header
but only when deleting the processing context.

In general, the IOMMU framework likes to group PCI devices together.
This prevents someone from assigning them to separate VMs using VFIO,
for example. The reason they shouldn't go to separate VMs is because
there could be DMA aliasing between endpoint devices, and because the
root complex device can access anything that endpoint devices can
access.
Unfortunately, this makes things difficult in the DMA layer since the
IOMMU framework freaks out if you try to attach a single device that is
also part of a group. First instinct might be to start using
iommu_attach_group instead of iommu_attach_device in the DMA layer but
that has problems of its own (it attaches *everyone* in the group as
soon as one client attaches). Besides all that, it's also a bit
annoying to have the root complex device in group since, in our
platform, it doesn't actually have any stream IDs assigned to it and it
doesn't do any DMA of its own, so it doesn't really make any logical
sense to attach it.
As a compromise, we can stop grouping PCI devices together by allocating
a new domain for each one. By doing so we no longer need to call
iommu_attach_group in the DMA layer, avoid the issues described above.
It should be noted that with this patch in place we can't securely do
any direct DMA assignment of PCI endpoint devices to separate VMs.

TSENS (Temperature sensor) driver does not need to map the
QFPROM region to obtain the gain and offset since these are
programmed in the boot initialization to the controller.
This removes the dependency for the application TSENS driver
to map the QFPROM physical region. Hence remove this property
as its optional. Also remove the default slope values that
are used in cases where the application TSENS driver uses it
for calibrationless mode.
