If there is no resourse to send packet via HTC, then check if interrupts
are not processed from that CE for last 3 seconds. If so, schedule a
tasklet to reap available entries. Also if Queue has reached 1024 entries
within 3 seconds, then also schedule tasklet.
This change is added because there is a case where intermittently
completion interrupts are not received from CE3 and hence adding
this WAR in host to come out of this issue scenario.

Currently, different modules had different ways of allowing
and preventing runtime suspend. Multiple debug mechanisms
were introduced and workarounds are present as well bloating
the runtime PM module.
This change is done to clean up and restructure HIF runtime
PM module. Modules using Runtime PM module need to register
with an ID present in hif_rtpm_client_id.
hif_rtpm_get() will increment the device usage_count and
prevent device from suspending. Based on argument type, if
system is suspended, subsequent resume action will be done.
hif_rtpm_put() will decrement the usage_count of device and
if it is NULL, based on type of put call, idle sequence will
start. Register HIF module and update respective get and put
calls done from HIF module.

in parallel, later any register accessing through PCIe bus will hit
NOC error.

As per current design, in failure path of hdd_wlan_start_modules,
mem_free of hif_ext_group is done (in cds_dp_close) before
free_irq (in hdd_hif_close), during next hdd_wlan_start_modules,
request_irq adds new handler entry to the list in irq_desc, this
leads to a crash on accessing older stale entry from irq handler,
so adding a bus_ops hif_grp_irq_deconfigure to free ext grp IRQs.

Any update to the SRNG TP/HP when the device is in low power
state would result in system errors. It is recommended to disable
EXT grp irqs and drain TXRX before sending power save enter command
to the FW. This will ensure that no interrupts are received while
in power save mode and as a result there wont be any HP/TP updates.

Issue1: Driver RTPM state is ON/NONE, Kernel state is RESUMING.
cdp_runtime_resume is already complete,
hif_pm_runtime_get return -E_INPROGRESS,
dp_tx_hw_enqueue will set the flush event,
but cdp_runtime_resume is already done,
this flush event will be handled only on next pkt tx.
Issue2: Driver RTPM state: Resuming
hif_pm_runtime_get returns -EBUSY,
dp_tx_hw_enqueue is interrupted by any IRQ,
cdp_runtime_resume is completed,
dp_tx_hw_enqueue will set the flush event,
This flush event will be handled only on next pkt tx.
Fix:
Introduce a link_state_up atomic variable in hif to track the link state
change by pld_cb.
Set atomic variable link_state_up=1 in pmo_core_psoc_bus_runtime_resume
just after pld_cb. pld_cb brings the PCIe bus out of suspend state.
Set atomic variable link_state_up=0 in pmo_core_psoc_bus_runtime_suspend
just before pld_cb. pld_cb puts the PCIe bus into suspend state.
Introduce dp_runtime_get and dp_runtime_put.
dp_runtime_get get refcount with increment of an atomic variable.
dp_runtime_put return refcount with decrement of this atomic variable.
If hif_pm_runtime_get returns -EBUSY or -EINPROGRESS,
take the dp runtime refcount using dp_runtime_get,
check if the link state is up, write TX ring HP,
return the dp runtime refcount using dp_runtime_put.
cdp_runtime_suspend should reject the suspend, if dp_runtime_get is non
zero.
cdp_runtime_resume should wait until dp_runtime_get becomes zero or time
out, then flush pending tx for runtime suspend.

Currently if the driver is in runtime suspend/suspending
state, any packet transmission will request for resume
via hif_pm_runtime_get.
Unfortunately there is a logging in the above API which
will lead to more time consumption in the NET_TX softirq
context. This can lead to other delay in processing other
softirqs in the system.
Fix this by skipping the logging in the packet transmission
path.

Currently DMA mask for the device is set during hif_enable_bus.
If the datapath memory prealloc feature is enabled, there are
a few dma memory allocation which is done before the DMA mask
is set for the device. This leads to the aforementioned dma
memory pre-allocation to be attempted at the default DMA mask.
Due to this the entire device capability of dma address might
not be used.
Add hif api to set dma mask before hif is initialized. This
is needed to set dma mask in case of datapath memory pre allocation.
