Date: Sat, 02 Mar 2013 18:53:01 +0530 From: Vivek Gautam <gautam.vivek@...sung.com> To: linux-usb@...r.kernel.org Cc: linux-kernel@...r.kernel.org, linux-omap@...r.kernel.org, linux-samsung-soc@...r.kernel.org, gregkh@...uxfoundation.org, balbi@...com, sarah.a.sharp@...ux.intel.com, kgene.kim@...sung.com, kishon@...com Subject: [PATCH v2 00/10] usb: dwc3/xhci/phy: Enable runtime power management This patch-series enables runtime power management on xhci-plat, dwc3-core, dwc3-exynos as well as on samsung-usb3 type PHY. This allows usb 3.0 host ports to be power managed at runtime. We also turn off the PHY ref_clk PLL, which supplies reference clock to USB3 type phy, when ports are not in use. Based on 'usb-next' alongwith following patch series: [PATCH v4 00/11] usb: dwc3: PM support patchset http://www.mail-archive.com/linux-usb@vger.kernel.org/msg14676.html [PATCH v2] usb: xhci: add the suspend/resume functionality http://www.mail-archive.com/linux-usb@vger.kernel.org/msg14614.html [PATCH v6 0/2] Adding USB 3.0 DRD-phy support for exynos5250 http://www.mail-archive.com/linux-usb@vger.kernel.org/msg15813.html Changes from v1: - Adding required PHY APIs to handle runtime power management instead of directly twiddling with phy->dev. - Handling runtime power management of usb PHYs in dwc3 core driver instead of in any glue layer. - Splitting the patch "[PATCH 4/4] usb: phy: samsung: Enable runtime power management on samsung-usb" to required number to bifurcate functionality.
