2014-04-30usb: phy: msm: Vote for corner of VDD CX instead of voltage of VDD CXIvan T. Ivanov
New platform uses RBCPR hardware feature, with that voting for absolute voltage of VDD CX is not required. Hence vote for corner of VDD CX which uses nominal corner voltage on VDD CX.

2014-04-30usb: phy: msm: Select secondary PHY via TCSRTim Bird
Select the secondary PHY using the TCSR register, if phy-num=1 in the DTS (or phy_number is set in the platform data). The SOC has 2 PHYs which can be used with the OTG port, and this code allows configuring the correct one. Note: This resolves the problem I was seeing where I couldn't get the USB driver working at all on a dragonboard, from cold boot. This patch depends on patch 5/14 from Ivan's msm USB patch set. It does not use DT for the register address, as there's no evidence that this address changes between SoC versions. Signed-off-by: Tim Bird <tim.bird@sonymobile.com> Signed-off-by: Ivan T.

Fix the value used for Parallel Transceiver Select (PTS) for the MSM USB controller. This is a standard chipidea PORTSC definition, where a PHY_TYPE of 10b (<<30) is ULPI and 11b (<<30) is SERIAL.

2014-04-30usb: phy: msm: Correct USB PHY Reset sequence for newer platformIvan T. Ivanov
On few legacy platforms, USB PHY is having dedicated reset clk. It is used to reset USB PHY after putting USB PHY into low power mode and for calibration of USB PHY. Putting USB PHY into low power mode is causing ulpi read/write timeout as expected. USB PHY reset clk is not available on newer platform. For 28nm PHY, reset USB PHY after resetting USB LINK. Also reset USB PHY using USB_PHY_PON bit with USB_OTG_HS_PHY_CTRL register after programming USB PHY Override registers as suggested with hardware programming guidelines. Signed-off-by: Ivan T.

2014-04-24usb: phy: mv_u3d: Remove usb phy driver for mv_u3dPaul Bolle
The usb phy driver for mv_u3d got added in v3.7 through commit a67e76ac904c ("usb: phy: mv_u3d: Add usb phy driver for mv_u3d"). It then depended on USB_MV_U3D. And that symbol depended on CPU_MMP3 at that time. But CPU_MMP3 has never been part of the tree. This means that this drive was unbuildable when it was added. In commit 60630c2eabd4 ("usb: gadget: mv_u3d: drop ARCH dependency") MV_U3D_PHY was made depended directly on CPU_MMP3. That kept it unbuildable, of course. Remove this driver. It can be re-added once its dependencies are part of the tree. Signed-off-by: Paul Bolle <pebolle@tiscali.nl> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-next Felipe writes: usb: patches for v3.15 another substantial pull request with new features all over the place. dwc3 got a bit closer towards hibernation support with after a few patches re-factoring code to be reused for hibernation. Also in dwc3 two new workarounds for known silicon bugs have been implemented, some randconfig build errors have been fixed, and it was taught about the new generic phy layer. MUSB on AM335x now supports isochronous transfers thanks to George Cherian's work. The atmel_usba driver got two crash fixes: one when no endpoint was specified in DeviceTree data and another when stopping the UDC in DEBUG builds. Function FS got a much needed fix to ffs_epfile_io() which was copying too much data to userspace in some cases. The printer gadget got a fix for a possible deadlock and plugged a memory leak. Ethernet drivers now use NAPI for RX which gives improved throughput. Other than that, the usual miscelaneous fixes, cleanups, and the like. Signed-of-by: Felipe Balbi <balbi@ti.com>

Both the PM_RUNTIME and PM_SLEEP callbacks call into the common msm_otg_{suspend,resume} routines, however these routines are only being built when CONFIG_PM_SLEEP. In addition, msm_otg_{suspend,resume} also depends on msm_hsusb_config_vddcx(), which is only built when CONFIG_PM_SLEEP. Fix the CONFIG_PM_RUNTIME, !CONFIG_PM_SLEEP case by changing the preprocessor conditional, and moving msm_hsusb_config_vddcx(). While we're here, eliminate the CONFIG_PM conditional for setting up the dev_pm_ops.
