phy: twl4030-usb: Fix unbalanced pm_runtime_enable on module reload

2016-02-10T06:16:01Z

If we reload phy-twl4030-usb, we get a warning about unbalanced pm_runtime_enable. Let's fix the issue and also fix idling of the device on unload before we attempt to shut it down. If we don't properly idle the PHY before shutting it down on removal, the twl4030 ends up consuming about 62mW of extra power compared to running idle with the module loaded.

phy: core: fix wrong err handle for phy_power_on

2016-02-10T06:15:41Z

If phy_pm_runtime_get_sync failed but we already enable regulator, current code return directly without doing regulator_disable. This patch fix this problem and cleanup err handle of phy_power_on to be more readable. Fixes: 3be88125d85d ("phy: core: Support regulator ...")

phy: Restrict phy-hi6220-usb to HiSilicon arm64

2016-02-03T06:25:28Z

The HiSilicon Hi6220 USB PHY is available in HiSilicon Hi6220 SoCs only. Restrict it to HiSilicon arm64, unless compile-testing. Signed-off-by: Geert Uytterhoeven Signed-off-by: Kishon Vijay Abraham I

Kishon writes: phy: for 4.5 *) new PHY driver for hi6220 usb and rcar gen3 usb2 *) deprecate phy-omap-control driver. phy-omap-control driver was added when there was no proper infrastructure for doing control module initialization. The phy-omap-control driver is not an 'actual' PHY driver and it was just a hack to do PHY related control module initialization. Now with SYSCON framework in the kernel, control module setttings can be done using APIs provided by syscon. *) usbphy-internal pll creates the needed 480MHz and is also a supply-clock back to the core clock-controller in Rockchip SoCs. This is now modeled as a real clock. *) calibrate mt65xx usb3 PHY for better eye diagram and receiver sensitivity. *) Miscellaneous cleanups. Signed-off-by: Kishon Vijay Abraham I

Felipe writes: usb: patches for v4.5 A ton of improvements to dwc2 have been made. The driver should be a lot more stable on v4.5 then ever before. Our good old dwc3 got a few cleanups and misc fixes and also added support to Xilinx's integration of this IP. Yoshihiro Shimoda gives us support for a new USB3 peripheral controller from Renesas. Other than these, the usual misc fixes all over the place.

phy: omap-usb2: use syscon framework API to power on/off the PHY

2015-12-21T08:56:28Z

Deprecate using phy-omap-control driver to power on/off the PHY, and use *syscon* framework to do the same. This handles powering on/off the PHY for the USB2 PHYs used in various TI SoCs. Signed-off-by: Kishon Vijay Abraham I

phy: omap-usb2: use omap_usb_power_off to power off the PHY during probe

2015-12-21T08:56:28Z

No functional change. Previously omap_control_phy_power() was used to power off the PHY during probe. But once phy-omap-usb2 driver is adapted to use syscon, omap_control_phy_power() cannot be used. Hence used omap_usb_power_off to power off the PHY. Signed-off-by: Kishon Vijay Abraham I Acked-by: Roger Quadros
