From dedd14925ec6f82a2840c009bc175e2b528ace8e Mon Sep 17 00:00:00 2001 From: Ulf Hansson Date: Mon, 30 Dec 2019 13:59:30 +0100 Subject: PM / Domains: Introduce a genpd OF helper that removes a subdomain We already have the of_genpd_add_subdomain() helper, but no corresponding of_genpd_remove_subdomain(), so let's add it. Subsequent changes starts to make use of it. Signed-off-by: Ulf Hansson Acked-by: Rafael J.
