From mboxrd@z Thu Jan 1 00:00:00 1970 From: Geert Uytterhoeven Subject: [PATCH v2] PM / clock_ops: Print acquired clock name in addition to con_id Date: Fri, 29 May 2015 18:35:31 +0200 Message-ID: <1432917331-3285-1-git-send-email-geert+renesas@glider.be> Return-path: Received: from laurent.telenet-ops.be ([195.130.137.89]:55259 "EHLO laurent.telenet-ops.be" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1755970AbbE2Qfa (ORCPT ); Fri, 29 May 2015 12:35:30 -0400 Sender: linux-pm-owner@vger.kernel.org List-Id: linux-pm@vger.kernel.org To: "Rafael J. Wysocki" , Kevin Hilman , Ulf Hansson , Grygorii Strashko Cc: linux-pm@vger.kernel.org, linux-clk@vger.kernel.org, Geert Uytterhoeven Currently the con_id of the acquired clock is printed for debugging purposes. But in several cases, the con_id is NULL, which doesn't provide much debugging information when printed. These cases are: - When explicitly passing a NULL con_id (which means the first clock tied to the device, if available), - When not using pm_clk_add(), but pm_clk_add_clk() (which takes a "struct clk *" directly). Hence print the actual clock name in addition to (and not instead of; thanks Grygorii Strashko!) the con_id. Note that the clock name is not available with legacy clock frameworks, and the hex pointer address will be printed instead. Signed-off-by: Geert Uytterhoeven --- This is v2 of "PM / clock_ops: Print acquired clock name instead of con_id". v2: - Print both clock and con_id, as suggested by Grygorii Strashko . --- drivers/base/power/clock_ops.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/drivers/base/power/clock_ops.c b/drivers/base/power/clock_ops.c index 442ce010559bf531..acef9f9f759a2530 100644 --- a/drivers/base/power/clock_ops.c +++ b/drivers/base/power/clock_ops.c @@ -68,7 +68,8 @@ static void pm_clk_acquire(struct device *dev, struct pm_clock_entry *ce) } else { clk_prepare(ce->clk); ce->status = PCE_STATUS_ACQUIRED; - dev_dbg(dev, "Clock %s managed by runtime PM.\n", ce->con_id); + dev_dbg(dev, "Clock %pC con_id %s managed by runtime PM.\n", + ce->clk, ce->con_id); } } -- 1.9.1
