Subject: [PATCH RESEND v3 2/5] PM: domains: Add the domain HW-managed mode to the summary
Date: Wed, 01 Nov 2023 11:04:08 +0200 [thread overview]
Message-ID: <20231101-gdsc-hwctrl-v3-2-0740ae6b2b04@linaro.org> (raw)
In-Reply-To: <20231101-gdsc-hwctrl-v3-0-0740ae6b2b04@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.
