Subject: [PATCH v1 0/4] Add missing features to FastRPC driver

This patch series adds the listed features that have been missing
in upstream fastRPC driver.

- Add early wakeup support to allow DSP user to send early response
  to CPU and improve fastrpc performance.
- Add polling mode support with which driver polls on memory to avoid
  CPU from going to low power modes.
- Add notifications frameworks to provide users with the DSP PD status
  notifications.
- Add a control mechanism to allow users to clean up DSP user PD

Ekansh Gupta (4):
  misc: fastrpc: Add early wakeup support for fastRPC driver
  misc: fastrpc: Add polling mode support for fastRPC driver
  misc: fastrpc: Add DSP PD notification support
  misc: fastrpc: Add support for users to clean up DSP user PD
