DP driver uses altmode glink interface whereas USB driver uses
UCSI interface for getting PPM based DP and USB related notification.
PPM based notification can come in different order specifically when
PPM is being restarted with SSR. With PPM SSR (here ADSP SSR) DP driver
is getting disconnect notification but USB driver won't be getting
disconnect notification. Once ADSP SSR is being completed, DP does go
through re-initialization and it does need USB DP combo PHY as
concurrent mode (2 lane USB and 2 lane DP usage). Current code goes
ahead disabling USB host mode with DP not connected notification.
In some case DP notification is coming after ADSP SSR is being completed
but before USB notification has gone through. This results into DP
initiailzation failure (aux timeout) due to USB host mode not started
configuring USB DP combo PHY into concurrent mode.
Consider case: USB DP concurrent mode usage with connecting MPA and
performing ADSP SSR
a. USB and DP are initialized (concurrent mode)
b. ADSP SSR is being performed
c. USB gets usb role as UFP/host mode
d. DP notifies as DP not connected
e. DP notified as 2 lane usage
Current code tears down USB host mode functionality with DP not connected
notification. If above step c notification comes after step d, then step e
based functionality goes through as USB host mode is active. Due to
asynchronous nature of notification, usage of multiple interfaces (altmode
link and UCSI) and ADSP doesn't notify USB disconnect with SSR (due to USB
audio use case requirement) whereas notify disconnect with DP. It is needed
to use refcounting mechnism to decide when to tear down USB host session to
allow sharing of USB DP combo PHY. This change adds ref count usage to
address above issue.

Pause will not be invoked through core control until after
walt has been initialized. However, the walt_pause apis are
made available to other vendor modules, and if those modules
attempt to invoke pause prior to walt being initialized, an
invalid reference to walt_drain_thread will be made.
Prevent the walt_pause and walt_resume apis from being used
until after walt has been properly initialized, walt_halt_init
has been called, and walt_drain_thread properly created.

When a kernel thread calls dma_buf_put() to release the last reference
to a dma-buf, fput_many() defers calling the release callback to a
workqueue. This means that if the same kernel thread later calls
dma_heap_buffer_alloc(), it has no guarantee that the memory from the
prior free is available, leading to random failures. As a short-term
workaround, call flush_delayed_fput() to ensure the free completes
synchronously.

This occurs because the message sent from TUIVM to PVM as part of the
file release callback is asynchonous. Resolve this by adding a new
message type which indicates when PVM has completed the free operation.
Additionally, define a separate obj_id instead of reusing the transaction
id for this purpose.
