From mboxrd@z Thu Jan 1 00:00:00 1970 From: Dolev Raviv Subject: [PATCH/RESEND V4 00/17] UFS: Power management support Date: Tue, 23 Sep 2014 10:31:22 +0300 Message-ID: <1411457499-8074-1-git-send-email-draviv@codeaurora.org> Return-path: Sender: linux-scsi-owner@vger.kernel.org To: James.Bottomley@HansenPartnership.com, hch@infradead.org Cc: linux-scsi@vger.kernel.org, linux-scsi-owner@vger.kernel.org, linux-arm-msm@vger.kernel.org, santoshsy@gmail.com, Dolev Raviv List-Id: linux-arm-msm@vger.kernel.org This patch seies introduces support for power management in the driver as well as vendor specific initialization - registers, clocks, voltage regulators etc. It includes also a rework for the init sequence and other PM pre-requisite such as write protection support, handling well-known LUN, error handling (retries), bkops, START_STOP unit command, and ICC levels settings. -- Changes from V2: - Replaced "[01/16] scsi: support well known logical units" with "[09/17] scsi: ufs: manually add well known logical - add patch "[PATCH V4 05/17] scsi: ufs: add voting support for host" - Fix couple of compilation issues introduced in V3 - Add a NULL pointer test to hba->vops before accessing it - Changed disable/enable irq with request/free irq Changes from V2: - Reordered scsi core patches - add patch "[PATCH V3 02/16] scsi: balance out autopm get/put calls in" - Minor changes/fixes to the patches: * "[PATCH V3 10/16] scsi: ufs: add UFS power management support" * "[PATCH V3 12/16] scsi: ufs: Add support for clock gating" * "[PATCH V3 16/16] scsi: ufs: definitions for phy interface" In order to address community concerns, and as a result of further development and testing. Changes from V1: - 6 new patches apended at the end - Allow overriding power configuration with controller support and preferences/capabilities - Allow overriding power choice with controller capabilities - Add support for clock gating and clock scaling - Add capability to control the auto bkops during suspend - Add misc changes for phy/unipro driver usage Dolev Raviv (2): scsi: ufs: refactor configuring power mode scsi: ufs: definitions for phy interface Raviv Shvili (1): scsi: ufs: add voting support for host controller power Sahitya Tummala (3): scsi: ufs: Add support for clock gating scsi: ufs: Add freq-table-hz property for UFS device scsi: ufs: Add support for clock scaling using devfreq framework Subhash Jadavani (6): scsi: balance out autopm get/put calls in scsi_sysfs_add_sdev() scsi: ufs: refactor query descriptor API support scsi: ufs: manually add well known logical units scsi: ufs: introduce well known logical unit in ufs scsi: ufs: add UFS power management support scsi: ufs: tune bkops while power managment events Sujit Reddy Thumma (4): scsi: ufs: Allow vendor specific initialization scsi: ufs: Add regulator enable support scsi: ufs: Add clock initialization support scsi: ufs: improve init sequence Yaniv Gardi (1): scsi: ufs: Active Power Mode - configuring bActiveICCLevel .../devicetree/bindings/ufs/ufshcd-pltfrm.txt | 41 + drivers/scsi/scsi_sysfs.c | 5 +- drivers/scsi/sd.c | 2 + drivers/scsi/sr.c | 2 + drivers/scsi/st.c | 2 + drivers/scsi/ufs/Kconfig | 2 + drivers/scsi/ufs/ufs.h | 132 +- drivers/scsi/ufs/ufshcd-pci.c | 55 +- drivers/scsi/ufs/ufshcd-pltfrm.c | 291 ++- drivers/scsi/ufs/ufshcd.c | 2481 ++++++++++++++++++-- drivers/scsi/ufs/ufshcd.h | 277 ++- drivers/scsi/ufs/ufshci.h | 9 +- drivers/scsi/ufs/unipro.h | 56 + 13 files changed, 3047 insertions(+), 308 deletions(-) -- 1.8.5.2 -- QUALCOMM ISRAEL, on behalf of Qualcomm Innovation Center, Inc. is a member of Code Aurora Forum, hosted by The Linux Foundation
