[PATCH 0/4] Add new driver for WCSS secure PIL loading

[Gokul Sriram Palanisamy]

This series depends on q6 clock removal series [1].

- Secure PIL is signed, split firmware images which only TrustZone (TZ) can
  authenticate and load. Linux kernel will send a request to TZ to
  authenticate and load the PIL images.

- When secure PIL support was added to the existing wcss PIL driver
  earlier in [2], Bjorn suggested not to overload the existing WCSS
  rproc driver [2], instead post a new driver for secure PIL alone.
  This series adds a new secure PIL driver for the same.
