From mboxrd@z Thu Jan 1 00:00:00 1970 From: Shawn Lin Subject: [PATCH v2 2/2] mmc: core: expose MMC_CAP2_NO_* to dt Date: Thu, 14 Jul 2016 16:26:04 +0800 Message-ID: <1468484764-32353-2-git-send-email-shawn.lin@rock-chips.com> References: <1468484764-32353-1-git-send-email-shawn.lin@rock-chips.com> Return-path: In-Reply-To: <1468484764-32353-1-git-send-email-shawn.lin@rock-chips.com> Sender: linux-kernel-owner@vger.kernel.org To: Ulf Hansson Cc: Adrian Hunter , Jaehoon Chung , Rob Herring , linux-mmc@vger.kernel.org, linux-kernel@vger.kernel.org, devicetree@vger.kernel.org, Shawn Lin List-Id: devicetree@vger.kernel.org The reason for why we expose these to dt is that some of the controller is unable to send special cmd type due to the hw limitation.
