From mboxrd@z Thu Jan 1 00:00:00 1970 From: Lucas Stach Subject: [PATCH 1/2] mmc: tegra: properly disable card clock Date: Mon, 29 Feb 2016 21:56:24 +0100 Message-ID: <1456779385-18996-1-git-send-email-dev@lynxeye.de> Return-path: Received: from ns.lynxeye.de ([87.118.118.114]:60848 "EHLO lynxeye.de" rhost-flags-OK-OK-OK-FAIL) by vger.kernel.org with ESMTP id S1750732AbcB2U4c (ORCPT ); Mon, 29 Feb 2016 15:56:32 -0500 Sender: linux-mmc-owner@vger.kernel.org List-Id: linux-mmc@vger.kernel.org To: Ulf Hansson , Adrian Hunter Cc: Stephen Warren , Thierry Reding , Alexandre Courbot , Jon Hunter , linux-mmc@vger.kernel.org, linux-tegra@vger.kernel.org The new code to do the clock rate setting externally to the SDMMC module has a shortcut to not propagate changes with a 0 rate to the CAR by simply bailing out. This breaks proper cutting of the card clock. Fix it by directly calling the correct sdhci function.
