I'm trying to get a GPIO input to trigger a PRU interrupt. The wiki states PRUSSEVTSEL should be set to 1 to receive GPIO interrupts from bank 0 and 1 as events 27 and 28. However the OMAP-L137 documentation makes no mention of PRUSSEVTSEL as part of system register CFGCHIP3. This is not necessarily incorrect, because the wiki doesn't say it's valid for the OMAP-L137. However I cannot find any other documentation about PRU interrupts that give the correct configuration. How should the INTC be configured correctly?
