usb: phy: msm: Select secondary PHY via TCSR 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.

usb: phy: msm: Fix PTS definitions for MSM USB controller 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. Fix the definitions and use them correctly in the driver code.

usb: phy: msm: Correct USB PHY Reset sequence for newer platform 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.

usb: phy: msm: Add support for secondary PHY control Allow support to use 2nd HSPHY with USB2 Core. Some platforms may have configuration to allow USB controller work with any of the two HSPHYs present. By default driver configures USB core to use primary HSPHY. Add support to allow user select 2nd HSPHY using DT parameter. Signed-off-by: Ivan T. Ivanov <iivanov@mm-sol.com> Cc: Manu Gautam <mgautam@codeaurora.org> Signed-off-by: Felipe Balbi <balbi@ti.com>

USB: OTG: msm: Add support for power management Implement runtime and system pm ops to put hardware into low power mode (LPM). As part of LPM, USB clocks are turned off, PHY is put into suspend state and PHY comparators are turned off if VBUS/Id notifications are not required from PHY.

USB: Add MSM OTG Controller driver This driver implements PHY initialization, clock management, ULPI IO ops and simple OTG state machine to kick host/peripheral based on Id/VBUS line status. VBUS/Id lines are tied to a reference voltage on some boards. Hence provide debugfs interface to select host/peripheral mode.
