Currently, the async job member of the ioctl structure is not
being initialized properly while making an unmap call to the
remote subsystem because of which an indeterminate value is used
to incorrectly mark this RPC call as an asynchronous job.
Initialize the async job field to NULL before making the RPC call
to unmap memory on DSP.

This change is a performance optimization. Instead of sending a DRI
deassert command at the end of a Data Ready DRI, the FW shall get a FIFO
empty internal signal. FW sets the don't deassert bit in relevant cases,
like Data Ready DRI, or SYSASSERT DRI.

Data read over SPI was guaranteed to be in a full burst size. This change
enables FW to raise the Data Ready DRI earlier, before the full burst is
ready. The driver must handle the case where data size reported by the HW
is less than a full burst, and then execute another iteration until the
whole burst is read.
This change causes a performance optimization, since the FW can raise the
Data Ready DRI earlier. The whole burst data is usually in place when the
driver handles it.

In case user space application requests for data size which is not a
multiple of the burst size and there is enough data in the drivers internal
buffer, a partial burst may be read by the application, which may cause
loss of burst boundary.
This patch fixes the above. In case the application supplies a buffer which
is smaller than the burst size, an error is returned to the application.

This driver adds support for sensing use cases over 60GHz frequency band.
Sensing uses 60GHz radio signal to 'sense' the environment, allowing
various use cases such as proximity detection, face recognition, gesture
detection and more.
The driver communicates with the QCA6436 HW using SPI bus. The driver
requires SPI and wil6210 drivers to operate.
