[V5,2/5] PM: domains: Add the domain HW-managed mode to the summary
Commit Message
From: Abel Vesa <abel.vesa@linaro.org>
Now that genpd supports dynamically switching the control for an
attached device between hardware- and software-mode, let's add this
information to the genpd summary in debugfs.

"under managed by column" would be good to add as well
