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.

Wake-IRQ can be received just before Kernel issuing
suspend_noirq callback, such wake-IRQ would not be
handled by Kernel. So check if any tasklet most likely
CE2 is pending and abort suspend_noirq if true.

During deinit process we free the IRQs and call kill tasklet.
There is the possibility that Tasklet might be running when we
call kill tasklet and as part of tasklet exit it will try to
enable the corresponding CE IRQ which has already been freed.
Adding check for IRQ free condition to avoid any IRQ enable
calls after IRQ free is done.

DHCP packet is received in the IPA exception path when
system is suspending. As part of DHCP packet processing,
WMI_PEER_SET_PARAM_CMDID is sent to FW after WOW is
enabled resulting in self recovery getting triggered by

Fix is to do an explicit system wakeup if a WMI command
has to be sent post WOW enablement.

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.

In P2P GO mode, on system suspend to s2idle state, bus
is suspended and D0-WoW is enabled. Ping requests from
P2P client cause the REO interrupt to fire but since
system is in s2idle state, system is not woken-up. This
results in destination unreachability or large rtt for
ping on P2P client.
Fix is to do explicit system wakeup when group interrupts
fire after system is in suspend state.
