Qualcomm Technologies Inc MSS QDSP6v5 Peripheral Image Loader

pil-qdsp6v5-mss is a peripheral image loader (PIL) driver. It is used for

loading QDSP6v5 (Hexagon) firmware images for modem subsystems into memory and

preparing the subsystem's processor to execute code. It's also responsible for

shutting down the processor when it's not needed.

- reg:		      Pairs of physical base addresses and region sizes of

		      memory mapped registers.

- reg-names:	      Names of the bases for the above registers. "qdsp6_base",

		      "rmb_base", "restart_reg" or "restart_reg_sec"(optional

		      for secure mode) are expected.

		      If "halt_base" is in same 4K pages this register then

		      this will be defined else "halt_q6", "halt_modem",

		      "halt_nc" is required.

       help

         This option enables the MSM subsystem restart framework.

         The MSM subsystem restart framework provides support to boot,

         It also notifies userspace of transitions between these states via

         sysfs.

         This option adds support for MSM System Monitor APIs using the GLINK
