IPA driver has all endpoint info at one place.
- provide IOCTL interface to get ep_pair info.
- Add support for new dtsi entry specifying auto config.
- Add support in ipa-usb driver for rmnet_cv2x.

As per current code, pm_lvl is read from DT on every probe
during system resume after suspend.
Therefore, rpm_lvl and spm_lvl updated by sysfs will be overwritten
with the pm_lvl read from DT during probe after resume from
system suspend.
To avoid this read pm_lvl from DT only when current pm_lvl
is invalid or during the first ufs probe after boot.

The regulator_is_enabled() API doesn't guarantee that CX gdsc has
collapsed at hardware. There could be a vote on the GDSC from another
subsystem like TZ. So poll the CX GDSCR register to ensure that CX has
indeed collapsed.

It has been observed that without gmu_clk, any active transactions will
cause that transaction to be stuck in QSMMU. As of now we don't halt
GBIF when moving to NAP state. So there is a possibility of transactions
inflight when gmu_clk is gated. This will cause transactions to be stuck
in QSMMU forever. This can eventually lead to GPU hang or TLB sync
timeout. So halt GBIF before moving to NAP.

During adreno_stop, GBIF halt is asserted to halt any new transaction from
GPU before GPU power collapse, but in current code it is cleared
immediately which can allow few GPU transactions to go through before gdsc
is turned-off and can result in issues.
To avoid this situation don't deassert this halt before GPU gdsc goes off.
It will deassert automatically when gdsc goes off but in case gdsc doesn't
toggle as it is a shared resource, it is deasserted during adreno_start to
ensure wake-up doesn't fail.

Currently during stall-on-fault recovery, we keep resuming SMMU and
check if GBIF halt succeeded. This is done to recover from a case where
a GPU block continuously initiated faulty transactions, which would keep
stalling SMMU. If we set CFCFG to 0 as part of handling the first fault,
all these transactions will be terminated and will not stall SMMU. This
simplifies the GBIF halt sequence and avoids resuming every time.

After PCIe link is up, scale PCIe resources based on the Gen
speed rather than the value of CX vote for the Gen speed. Before
CX vote was the only factor for scaling resources. This is an
incorrect assumption as additional resources can be added and
do not have any dependency with CX. Therefore, remove the
dependency on CX and bind it to the Gen speed instead.
