From mboxrd@z Thu Jan 1 00:00:00 1970 From: Laxman Dewangan Subject: [PATCH 1/2] regulator: palmas: configure enable time for LDOs Date: Tue, 10 Sep 2013 16:48:07 +0530 Message-ID: <1378811888-2268-1-git-send-email-ldewangan@nvidia.com> Mime-Version: 1.0 Content-Type: text/plain Return-path: Sender: linux-doc-owner@vger.kernel.org To: broonie@kernel.org Cc: rob.herring@calxeda.com, mark.rutland@arm.com, swarren@wwwdotorg.org, rob@landley.net, devicetree@vger.kernel.org, linux-doc@vger.kernel.org, linux-kernel@vger.kernel.org, lgirdwood@gmail.com, Laxman Dewangan List-Id: devicetree@vger.kernel.org As per datasheet (Referred TPS65913), the on-time for LDO is 500micro second. If LDO6 is in vibrator mode then the on-time is 2000us. Set the enable_time on regulator descriptor accordingly.
