From mboxrd@z Thu Jan 1 00:00:00 1970 From: Paul Walmsley Subject: [PATCH 10/12] ARM: OMAP3: hwmod data: fix IVA interface clock Date: Wed, 07 Mar 2012 19:38:39 -0700 Message-ID: <20120308023839.8205.66682.stgit@dusk> References: <20120308023614.8205.78768.stgit@dusk> Mime-Version: 1.0 Content-Type: text/plain; charset="utf-8" Content-Transfer-Encoding: 7bit Return-path: Received: from utopia.booyaka.com ([72.9.107.138]:45808 "EHLO utopia.booyaka.com" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1751894Ab2CHCmL (ORCPT ); Wed, 7 Mar 2012 21:42:11 -0500 In-Reply-To: <20120308023614.8205.78768.stgit@dusk> Sender: linux-omap-owner@vger.kernel.org List-Id: linux-omap@vger.kernel.org To: linux-omap@vger.kernel.org, linux-arm-kernel@lists.infradead.org The OMAP3 hwmod data listed iva2_ck as an interface clock between the IVA and L3. This is incorrect. iva2_ck is not an interface clock. Since it cannot auto-idle, specifying it here prevents the IVA and at least one of the CORE clockdomains from going idle, which causes PM problems such as these upon system suspend: [ 70.626129] Powerdomain (iva2_pwrdm) didn't enter target state 1 [ 70.626190] Powerdomain (core_pwrdm) didn't enter target state 1 Fix by specifying the actual interface clock in the hwmod data.
