phy: omap-usb2: Enable runtime PM of omap-usb2 phy properly

2014-11-05T22:34:06Z

The USB OTG port does not work since v3.16 on omap platform. This is a regression introduced by the commit eb82a3d846fa (phy: omap-usb2: Balance pm_runtime_enable() on probe failure and remove). This because the call to pm_runtime_enable() function is moved after the call to devm_phy_create() function, which has side effect since later in the subsequent calls of devm_phy_create() there is a check with pm_runtime_enabled() to configure few things.

phy: remove .owner field for drivers using module_platform_driver

2014-09-24T09:48:34Z

This patch removes the superflous .owner field for drivers which use the module_platform_driver or platform_driver_register api, as this is overriden in __platform_driver_register. Signed-off-by: Peter Griffin Signed-off-by: Kishon Vijay Abraham I

phy: exynos-dp-video: Use syscon support to control pmu register

2014-09-24T09:48:34Z

Currently the DP_PHY_ENABLE register is mapped in the driver, and accessed to control power to the PHY. With mfd-syscon and regmap interface available at our disposal, it's wise to use that instead of using a 'reg' property for the controller and allocating a memory resource for that. To facilitate this, we have added another compatible string for Exynso5420 SoC to acquire driver data which contains different DP-PHY-CONTROL register offset.

phy: phy-stih41x-usb: Add usb phy support for STiH41x SoCs.

2014-09-24T09:48:33Z

This driver adds support for USB (1.1 and 2.0) phy for STiH415 and STiH416 System-On-Chips from STMicroelectronics. Signed-off-by: Maxime Coquelin Signed-off-by: Peter Griffin Signed-off-by: Kishon Vijay Abraham I

phy: phy-stih407-usb: Add usb picoPHY driver found on stih407 SoC family

2014-09-24T09:48:33Z

This is the generic phy driver for the picoPHY ports used by the USB2 and USB3 Host controllers when controlling usb2/1.1 devices. It is found on STiH407 SoC family from STMicroelectronics. Signed-off-by: Giuseppe Cavallaro Signed-off-by: Peter Griffin Signed-off-by: Kishon Vijay Abraham I

usb: phy: twl4030-usb: Use mutex instead of spinlock for protecting the data

2014-09-24T09:48:33Z

We're using threaded irq on a I2C bus and we're sleeping in twl4030_usb_irq() as it calls twl4030_usb_linkstat() which calls the i2c functions. If we ever need to lock for longer I2C transaction sequences a mutex will allow us to do that easily. Signed-off-by: Tony Lindgren Signed-off-by: Kishon Vijay Abraham I

usb: phy: twl4030-usb: Remove asleep and rely on runtime PM

2014-09-24T09:48:33Z

There's no longer need for tracking the phy state in the driver with asleep, we can now rely on runtime PM. Signed-off-by: Tony Lindgren Signed-off-by: Kishon Vijay Abraham I

usb: phy: twl4030-usb: Move code from twl4030_phy_power to the runtime PM calls

2014-09-24T09:48:32Z

We don't need twl4030_phy_power() any longer now that we have the runtime PM calls. Let's get rid of it as it's confusing. No functional changes, just move the code and use res instead of ret as we are not returning that value. Signed-off-by: Tony Lindgren Signed-off-by: Kishon Vijay Abraham I

usb: phy: twl4030-usb: Simplify phy init to use runtime PM

2014-09-24T09:48:32Z

We can now let the interrupt and delayed work do all that's needed with runtime PM. Signed-off-by: Tony Lindgren Signed-off-by: Kishon Vijay Abraham I

usb: phy: twl4030-usb: Remove unused irq_enabled

2014-09-24T09:48:32Z

It's not being used any longer. Signed-off-by: Tony Lindgren Signed-off-by: Kishon Vijay Abraham I
