Date: Wed, 09 Apr 2014 15:20:15 +0200 From: Krzysztof Kozlowski <k.kozlowski@...sung.com> To: MyungJoo Ham <myungjoo.ham@...sung.com>, Chanwoo Choi <cw00.choi@...sung.com>, linux-kernel@...r.kernel.org Cc: Krzysztof Kozlowski <k.kozlowski@...sung.com> Subject: [PATCH 4/4] extcon: max8997: Use power efficient workqueue for delayed cable detection Schedule delayed cable detection work on power efficient workqueue so the scheduler won't wake up idle core for that work. This extends the idle time for CPU cores and conserves power.
