HWMOD Framework Enhancements

Reset Management Support in HWMOD

• Problem Statement
  • Most processor IPs do have a HW reset signal controlled by the PRM.
  • There is currently no abstraction layer to control the PRM reset register.
  • Since these reset signals are IP specific, they should be controlled manually by the driver code.

• Proposed Solution
  • Add two APIs for asserting / deasserting reset lines in hwmods processor that require manual reset control.
  • Add one API to get the current reset state.

• RFC patches can be found at
  • RFC Patches Branch: hwmod_reset
