Subject: [RFC PATCH 3/3] ARM: keystone: pm_domain: setup clk pm domain clocks from DT
Date: Fri, 25 Jul 2014 17:47:01 +0000 [thread overview]
Message-ID: <1406313096-29761-4-git-send-email-grygorii.strashko@ti.com> (raw)
In-Reply-To: <1406313096-29761-1-git-send-email-grygorii.strashko@ti.com>
This patch implements custom pm_clk_notifier callback for Keystone 2
CLK PM domain which fills list of clocks for Device with all
clocks assigned to this Device in DT.
After this patch .con_ids field in pm_clk_notifier_block is not
used and there are no limitation for clocks names in DT any more.
