From: Suman Anna <s-anna@xxxxxx> The remoteproc core creates certain standard debugfs entries, that does not give a whole lot of useful information for the PRUs. The PRU remoteproc driver is enhanced to add additional debugfs entries for PRU. These will be auto-cleaned up when the parent rproc debug directory is removed. The enhanced debugfs support adds two new entries: 'regs' and 'single_step'. The 'regs' dumps out the useful CTRL sub-module registers as well as each of the 32 GPREGs and CT_REGs registers. The GPREGs and CT_REGs though are printed only when the PRU is halted and accessible as per the IP design.
If the driver used regmap to access the CTRL I/O memory, then 'regs' wouldn't be needed since regmap already does debugfs.
