From mboxrd@z Thu Jan 1 00:00:00 1970 From: Kishon Vijay Abraham I Subject: [PATCH v2 00/16] omap_hsmmc: regulator usage cleanup and fixes Date: Mon, 3 Aug 2015 17:56:25 +0530 Message-ID: <1438604801-11823-1-git-send-email-kishon@ti.com> Mime-Version: 1.0 Content-Type: text/plain Return-path: Sender: linux-mmc-owner@vger.kernel.org To: ulf.hansson@linaro.org, afenkart@gmail.com, tony@atomide.com, devicetree@vger.kernel.org, linux-kernel@vger.kernel.org, linux-mmc@vger.kernel.org, linux-omap@vger.kernel.org Cc: nsekhar@ti.com, kishon@ti.com List-Id: devicetree@vger.kernel.org Changes from v1: *) return on -EPROBE_DEFER and other fatal errors. (Don't return only if the return value is -ENODEV) *) Remove the beagle x15 dts patch. It can be part of a different series. *) Avoid using regulator_is_enabled for vqmmc since if the regulator is shared and the other users are not using regulator_is_enabled then there can be unbalanced regulator_enable/regulator_disable This patch series does the following *) Uses devm_regulator_get_optional() for vmmc and then removes the CONFIG_REGULATOR check altogether. *) return on -EPROBE_DEFER and any other fatal errors *) enable/disable vmmc_aux regulator based on prior state I've pushed this patch series to git://git.ti.com/linux-phy/linux-phy.git mmc_regulator_cleanup_fixes_v2 Please note the branch also has the pbias fixes [1] & [2]. [1] -> https://lkml.org/lkml/2015/7/27/358 [2] -> https://lkml.org/lkml/2015/7/27/391 This series is in preparation for implementing the voltage switch sequence so that UHS cards can be supported. Did basic read/write test in J6, J6 Eco, Beagle-x15, AM437x EVM, Beaglebone black, OMAP5 uEVM and OMAP4 PANDA.
