7 title: Keystone 2 DSP GPIO controller
10 - Grygorii Strashko <grygorii.strashko@ti.com>
13 HOST OS userland running on ARM can send interrupts to DSP cores using
14 the DSP GPIO controller IP. It provides 28 IRQ signals per each DSP core.
17 For example TCI6638K2K SoC has 8 DSP GPIO controllers:
18 - 8 for C66x CorePacx CPUs 0-7
