* Generic Subsystem Peripheral Image Loader

subsys-pil-tz is a generic peripheral image loader (PIL) driver. It is

used for loading the firmware images of the 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.

Required properties:

- compatible:	      Must be "qcom,pil-tz-generic"

- qcom,firmware-name: Base name of the firmware image.

Optional properties:

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

		      memory mapped registers.

- reg-names:	      Names of the bases for the above registers. Not required for

		      PIL usage. Ex. "wrapper_base", "vbif_base".

- interrupts:	      Subsystem to Apps watchdog bite interrupt.

- vdd_'reg'-supply: Reference to the regulator that supplies the corresponding

		    'reg' domain.

- qcom,proxy-reg-names: Names of the regulators that need to be turned on/off

			during proxy voting/unvoting.

- qcom,active-reg-names: Names of the regulators that need to be turned on for the

			subsystem to run. Turned off when the subsystem is shutdown.

- qcom,vdd_'reg'-uV-uA:    Voltage and current values for the 'reg' regulator.

- qcom,proxy-clock-names:  Names of the clocks that need to be turned on/off during

			   proxy voting/unvoting.

- qcom,active-clock-names: Names of the clocks that need to be turned on for the

			   subsystem to run. Turned off when the subsystem is shutdown.

- clock-names:	      Names of all the clocks that are accessed by the subsystem.

- qcom,<clock-name>-freq: Frequency to be set for that clock in Hz. If the property

			  isn't added for a clock, then the default clock frequency

			  would be set to 19200000 Hz.

- qcom,msm-bus,name:  Name of the bus client for the subsystem.

- qcom,msm-bus,num-cases: Number of use-cases.

- qcom,msm-bus,num-paths: Number of paths.

- qcom,msm-bus,active-only: If not set, uses the dual context by default.

- qcom,msm-bus,vectors-KBps: Vector array of master id, slave id, arbitrated

			     bandwidth and instantaneous bandwidth.

- qcom,pas-id:	      pas_id of the subsystem.

- qcom,proxy-timeout-ms: Proxy vote timeout value for the subsystem.

- qcom,smem-id:	      ID of the SMEM item for the subsystem.

- qcom,is-not-loadable: Boolean. Present if the subsystem's firmware image does not

			need to be loaded.

- qcom,pil-no-auth: Boolean. Present if the subsystem is not authenticated and brought

		    out of reset by using the PIL ops.

- qcom,mem-protect-id: Virtual ID used by PIL to call into TZ/HYP to protect/unprotect

			subsystem related memory.

- qcom,gpio-err-fatal: GPIO used by the subsystem to indicate error fatal to the apps.

- qcom,gpio-err-ready: GPIO used by the subsystem to indicate error ready to the apps.

- qcom,gpio-proxy-unvote: GPIO used by the subsystem to trigger proxy unvoting in

			  the apps.

- qcom,gpio-force-stop: GPIO used by the apps to force the subsystem to shutdown.

- qcom,gpio-stop-ack: GPIO used by the subsystem to ack force stop or a graceful stop

		      to the apps.

- qcom,restart-group: List of subsystems that will need to restart together.

- qcom,keep-proxy-regs-on: Boolean. Present if during proxy unvoting, PIL needs to leave

			the regulators enabled after removing the voltage/current votes.

- qcom,edge:		GLINK logical name of the remote subsystem

- qcom,ssctl-instance-id: Instance id used by the subsystem to connect with the SSCTL

			  service.

- qcom,sysmon-id:	platform device id that sysmon is probed with for the subsystem.

- qcom,pil-force-shutdown: Boolean. If set, the SSR framework will not trigger graceful shutdown

                           on behalf of the subsystem driver.

- qcom,pil-generic-irq-handler: generic interrupt handler used for communication with subsytem

				based on bit values in scsr registers.

- qcom,spss-scsr-bits: array of bit positions into the scsr registers used in generic handler.

- qcom,complete-ramdump: Boolean. If set, complete ramdump i.e. region between start address of

			first segment to end address of last segment will be collected without

			leaving any hole in between.

- qcom,ignore-ssr-failure: Boolean. If set, SSR failures are not considered fatal.

- qcom,signal-aop: Boolean. If set, when subsystem is brought up, pil will send a notification

			to AOP through qmp mailbox driver.

config MSM_SERVICE_LOCATOR

	bool "Service Locator"

	depends on MSM_QMI_INTERFACE

	help

	  The Service Locator provides a library to retrieve location

	  information given a service identifier. Location here translates

	  to what process domain exports the service, and which subsystem

	  that process domain will execute in.

config MSM_SERVICE_NOTIFIER

	bool "Service Notifier"

	depends on MSM_SERVICE_LOCATOR && MSM_SUBSYSTEM_RESTART

	help

	  The Service Notifier provides a library for a kernel client to

	  register for state change notifications regarding a remote service.

	  A remote service here refers to a process providing certain services

	  like audio, the identifier for which is provided by the service

	  locator.

config MSM_SUBSYSTEM_RESTART

	bool "MSM Subsystem Restart"

	help

	  This option enables the MSM subsystem restart framework.

	  The MSM subsystem restart framework provides support to boot,

	  shutdown, and restart subsystems with a reference counted API.

	  It also notifies userspace of transitions between these states via

	  sysfs.

config MSM_PIL

	bool "Peripheral image loading"

	select FW_LOADER

	default n

	help

	  Some peripherals need to be loaded into memory before they can be

	  brought out of reset.

	  Say yes to support these devices.

config MSM_SYSMON_GLINK_COMM

	bool "MSM System Monitor communication support using GLINK transport"

	depends on MSM_GLINK && MSM_SUBSYSTEM_RESTART

	help

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

	  transport layer. The APIs provided may be used for notifying

	  subsystems within the SoC about other subsystems' power-up/down

	  state-changes.

config MSM_PIL_SSR_GENERIC

	tristate "MSM Subsystem Boot Support"

	depends on MSM_PIL && MSM_SUBSYSTEM_RESTART

	help

	  Support for booting and shutting down MSM Subsystem processors.

	  This driver also monitors the SMSM status bits and the watchdog

	  interrupt for the subsystem and restarts it on a watchdog bite

	  or a fatal error. Subsystems include LPASS, Venus, VPU, WCNSS and

	  BCSS.
