Dgpio-dsp-keystone.txt1 Keystone 2 DSP GPIO controller bindings
3 HOST OS userland running on ARM can send interrupts to DSP cores using
4 the DSP GPIO controller IP. It provides 28 IRQ signals per each DSP core.
7 For example TCI6638K2K SoC has 8 DSP GPIO controllers:
8 - 8 for C66x CorePacx CPUs 0-7
10 Keystone 2 DSP GPIO controller has specific features:
11 - each GPIO can be configured only as output pin;
12 - setting GPIO value to 1 causes IRQ generation on target DSP core;
13 - reading pin value returns 0 - if IRQ was handled or 1 - IRQ is still
17 - compatible: should be "ti,keystone-dsp-gpio"
