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. At the same time, add the compatibility string for tegra194-hsp, which is backwards compatible with tegra186.
Signed-off-by: Mikko Perttunen <mperttu...@nvidia.com> --- Notes: v2: - Edited commit message to not say that doorbell interrupts cannot be routed to shared interrupts. - Added tegra194 compatibility string.
