* This API allows the Host to access Target registers directly
* and relatively efficiently over PCIe.
* This allows the Host to avoid extra overhead associated with
* sending a message to firmware and waiting for a response message
* from firmware, as is done on other interconnects.
*
* Yet there is some complexity with direct accesses because the
* Target's power state is not known a priori. The Host must issue
* special PCIe reads/writes in order to explicitly wake the Target
* and to verify that it is awake and will remain awake.
*
* Usage:
/* Target exposes its registers for direct access. However before host can
* access them it needs to make sure the target is awake (ath10k_pci_wake,
* ath10k_pci_wake_wait, ath10k_pci_is_awake). Once target is awake it won't go
* to sleep unless host tells it to (ath10k_pci_sleep).
*
* Use ath10k_pci_read32 and ath10k_pci_write32 to access Target space.
* These calls must be bracketed by ath10k_pci_wake and
* ath10k_pci_sleep. A single BEGIN/END pair is adequate for
* multiple READ/WRITE operations.
* If host tries to access target registers without waking it up it can
* scribble over host memory.
*
* Use ath10k_pci_wake to put the Target in a state in
* which it is legal for the Host to directly access it. This
* may involve waking the Target from a low power state, which
* may take up to 2Ms!
*
* Use ath10k_pci_sleep to tell the Target that as far as
* this code path is concerned, it no longer needs to remain
* directly accessible. BEGIN/END is under a reference counter;
* multiple code paths may issue BEGIN/END on a single targid.
* If target is asleep waking it up may take up to even 2ms.
