From mboxrd@z Thu Jan 1 00:00:00 1970 From: Geert Uytterhoeven Date: Wed, 14 Jan 2015 12:11:24 +0000 Subject: [PATCH v2 6/6] drivers: sh: Disable PM runtime for multi-platform sh73a0 with genpd Message-Id: <1421237484-16847-7-git-send-email-geert+renesas@glider.be> List-Id: References: <1421237484-16847-1-git-send-email-geert+renesas@glider.be> In-Reply-To: <1421237484-16847-1-git-send-email-geert+renesas@glider.be> MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: linux-arm-kernel@lists.infradead.org If the default PM domain using PM_CLK is used for PM runtime, the real PM domain(s) cannot be registered from DT later. Hence do not enable it when running a multi-platform kernel with genpd support on an sh73a0. The R-Mobile PM domain driver will take care of PM runtime management of the module clocks. The default PM domain is still needed for: - platforms without genpd support, - the legacy (non-DT) case, where genpd may take over later, except for the C5 "always on" PM domain.
