* phy: omap-usb2: Enable runtime PM of omap-usb2 phy properlyOussama Ghorbel2014-11-051-2/+4
| | | | | | | | | | | | | | | | | | 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: exynos-dp-video: Use syscon support to control pmu registerVivek Gautam2014-09-241-25/+54
| | | | | | | | | | | | | | | | | 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: Renesas R-Car Gen2 PHY driverSergei Shtylyov2014-09-243-0/+349
| | | | | | | | | | | | | | | | | | This PHY, though formally being a part of Renesas USBHS controller, contains the UGCTRL2 register that controls multiplexing of the USB ports (Renesas calls them channels) to the different USB controllers: channel 0 can be connected to either PCI EHCI/OHCI or USBHS controllers, channel 2 can be connected to PCI EHCI/OHCI or xHCI controllers. This is a new driver for this USB PHY currently already supported under drivers/ usb/phy/. The reason for writing the new driver was the requirement that the multiplexing of USB channels to the controller be dynamic, depending on what USB drivers are loaded, rather than static as provided by the old driver. The infrastructure provided by drivers/phy/phy-core.c seems to fit that purpose ideally. The new driver only supports device tree probing for now.

* usb: phy: twl4030-usb: Fix lost interrupts after ID pin goes downTony Lindgren2014-08-241-23/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 249751f22380 ("usb: phy: twl4030-usb: poll for ID disconnect") added twl4030_id_workaround_work() to deal with lost interrupts after ID pin goes down. Looks like commit f1ddc24c9e33 ("usb: phy: twl4030-usb: remove *set_suspend* and *phy_init* ops") changed things around for the generic phy framework, and delayed work no longer got called except initially during boot. The PHY connect and disconnect interrupts for twl4030-usb are not working after disconnecting a USB-A cable from the board, and the deeper idle states for omap are blocked as the USB controller stays busy. The issue can be solved by calling delayed work from twl4030_usb_irq() when ID pin is down and the PHY is not asleep like we already do in twl4030_id_workaround_work(). But as both twl4030_usb_irq() and twl4030_id_workaround_work() already do pretty much the same thing, let's call twl4030_usb_irq() from twl4030_id_workaround_work() instead of adding some more duplicate code. We also must call sysfs_notify() only when we have an interrupt and not from the delayed work as notified by Grazvydas Ignotas <notasas@gmail.com>.

* usb: phy: twl4030-usb: Fix regressions to runtime PM on omapsTony Lindgren2014-08-241-25/+63
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 30a70b026b4cd ("usb: musb: fix obex in g_nokia.ko causing kernel panic") attempted to fix runtime PM handling for PHYs that are on the I2C bus. Commit 3063a12be2b0 ("usb: musb: fix PHY power on/off") then changed things around to enable of PHYs that rely on runtime PM. These changes however broke idling of the PHY and causes at least 100 mW extra power consumption on omaps, which is a lot with the idle power consumption being below 10 mW range on many devices. As calling phy_power_on/off from runtime PM calls in the USB causes complicated issues with I2C connected PHYs, let's just let the PHY do it's own runtime PM as needed. This leaves out the dependency between PHYs and USB controller drivers for runtime PM. Let's fix the regression for twl4030-usb by adding minimal runtime PM support. This allows idling the PHY on disconnect. Note that we are changing to use standard runtime PM handling for twl4030_phy_init() as that function just checks the state and does not initialize the PHY. The PHY won't get initialized until in twl4030_phy_power_on().

* | | phy: add a driver for the Berlin SATA PHYAntoine Ténart2014-07-223-0/+292
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Berlin SoC has a two SATA ports. Add a PHY driver to handle them. The mode selection can let us think this PHY can be configured to fit other purposes. But there are reasons to think the SATA mode will be the only one usable: the PHY registers are only accessible indirectly through two registers in the SATA range, the PHY seems to be integrated and no information tells us the contrary. For these reasons, make the driver a SATA PHY driver. Signed-off-by: Antoine Ténart <antoine.tenart@free-electrons.com> Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since the USB 2.0 PHYs are required with EHCI/OHCI USB drivers and USB gadget controller supported by the DWC2 gadget driver, make it depend on them and default to ARCH_EXYNOS as they are meant for Exynos platforms. Also, make the sub-drivers silent options enabling them based on the SoC platforms that they are meant to work with. This will make life easier for end users who do not have any way knowing the dependencies.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for Exynos3250 SoC to Exynos2USB PHY driver. Although Exynos3250 has only one device phy interface, the register layout and all operations that are required to get it enabled are almost same as on Exynos4x12. The only different is one more register (REFCLKSEL) which need to be set and lack of MODE SWITCH register.
