* usb: phy: msm: Vote for corner of VDD CX instead of voltage of VDD CXIvan T. Ivanov2014-04-30
| | | | | | | | | | 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. Signed-off-by: Ivan T.

* usb: phy: msm: Add support for secondary PHY controlIvan T. Ivanov2014-04-30
| | | | | | | | | | | | 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.

* usb: phy: msm: Remove unused pclk_src_nameIvan T. Ivanov2014-04-30
| | | | | | | | There are no references to 'pclk_src_name' in plaform code, so it is unused. Signed-off-by: Ivan T. Ivanov <iivanov@mm-sol.com> Signed-off-by: Felipe Balbi <balbi@ti.com>
* usb: phy: msm: Replace custom enum usb_mode_type with enum usb_dr_modeIvan T. Ivanov2014-04-30
| | | | | | | | | | | | Use enum usb_dr_mode and drop default usb_dr_mode from platform data. USB DT bindings states: dr_mode: "...In case this attribute isn't passed via DT, USB DRD controllers should default to OTG...", so remove redundand field. Signed-off-by: Ivan T.

* usb: phy: msm: Move global regulators variables to driver stateIvan T. Ivanov2014-04-30

* usb: phy: msm: Move mach dependent code to platform dataIvan T. Ivanov2014-01-09
| | | | | | | | | | | | | | | | | | | | | | | This patch fix compilation error when driver is compiled in multi-platform builds. drivers/built-in.o: In function `msm_otg_link_clk_reset': ./drivers/usb/phy/phy-msm-usb.c:314: undefined reference to `clk_reset' ./drivers/usb/phy/phy-msm-usb.c:318: undefined reference to `clk_reset' Use platform data supplied reset handlers and adjust error messages reported when reset sequence fail. This is an intermediate step before adding support for reset framework and newer targets. Signed-off-by: Ivan T.

* USB: OTG: msm: Implement charger detectionPavankumar Kondeti2011-05-06
| | | | | | | | | | | | | | | | | Implement good battery algorithm defined in the battery charging V1.2 spec for detecting different charging ports. USB hardware is put into low power mode when connected to a dedicated charging port. vbus_draw and set_power methods are implemented for determining the allowed current from Host in different states (un-configured/suspend/configured). The charger block is implemented using vendor specific registers and the PHY used in MSM8960(28nm PHY) different from older targets like MSM8x60 and MSM7x30(45nm PHY). The PHY vendor and product id registers are not implemented in the above chipsets. Hence PHY type is passed via platform data.

| | | | | | | | | | | | HSUSB core clock is derived from daytona fabric clock and for HSUSB operational require minimum core clock at 55MHz. Since, HSUSB cannot tolerate daytona fabric clock change in the middle of HSUSB operational, vote for maximum Daytona fabric clock while usb is operational Signed-off-by: Anji jonnala <anjir@codeaurora.org> Signed-off-by: Pavankumar Kondeti <pkondeti@codeaurora.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* USB: Rename "msm72k_otg.c" to "msm_otg.c"Pavankumar Kondeti2011-03-07
| | | | | | | | This driver is used across all MSM SoCs. Hence give a generic name. All Functions and strutures are also using "msm_otg" as prefix. Signed-off-by: Pavankumar Kondeti <pkondeti@codeaurora.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* USB: OTG: msm: Add support for power managementPavankumar Kondeti2010-12-10
| | | | | | | | | | 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 driverPavankumar Kondeti2010-12-10
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.
