Commit Message

Mikko Perttunen July 2, 2018, 11:40 a.m.
HSP interrupts can be routed through exposed "shared interrupts". These
interrupts can be mapped to various internal interrupt lines. Add
interrupt properties for shared interrupts to the tegra186-hsp device
tree bindings.

Notes:
    v2:
    - Edited commit message to not say that doorbell interrupts cannot be
      routed to shared interrupts.
    - Added tegra194 compatibility string.
    
    v3:
    - Added Jon's A-b and Rob's R-b
