Subject: [RFC PATCH 5/9] PM: domains: Add of_genpd_add_provider_simple_noclk()
Date: Tue, 12 Oct 2021 01:57:03 +0900 [thread overview]
Message-ID: <20211011165707.138157-6-marcan@marcan.st> (raw)
In-Reply-To: <20211011165707.138157-1-marcan@marcan.st>
This is analogous to of_genpd_add_provider_simple(), but calls
dev_pm_opp_of_add_table_noclk() instead of dev_pm_opp_of_add_table().
