usb: dwc3: core: purge dev_dbg() calls

2015-12-15T15:12:41Z

The last few dev_dbg() messages are converted to tracepoints and we can finally ignore dev_dbg() messages during debug sessions. Signed-off-by: Felipe Balbi

usb: dwc3: Add dis_enblslpm_quirk

2015-10-09T21:06:59Z

Add a quirk to clear the GUSB2PHYCFG.ENBLSLPM bit, which controls whether the PHY receives the suspend signal from the controller. Cc: # v3.18+ Signed-off-by: John Youn Signed-off-by: Felipe Balbi

usb: dwc3: Support Synopsys USB 3.1 IP

2015-10-09T21:06:58Z

This patch allows the dwc3 driver to run on the new Synopsys USB 3.1 IP core, albeit in USB 3.0 mode only. The Synopsys USB 3.1 IP (DWC_usb31) retains mostly the same register interface and programming model as the existing USB 3.0 controller IP (DWC_usb3). However the GSNPSID and version numbers are different. Add checking for the new ID to pass driver probe. Also, since the DWC_usb31 version number is lower in value than the full GSNPSID of the DWC_usb3 IP, we set the high bit to identify DWC_usb31 and to ensure the values are higher. Finally, add a documentation note about the revision numbering scheme. Any future revision checks (for STARS, workarounds, and new features) should take into consideration how it applies to both the 3.1/3.0 IP.

usb: dwc3: core: convert to unified device property interface

2015-09-27T15:54:31Z

No functional affect on existing platforms, but the driver is now ready to extract the properties also from ACPI tables as well as from DT. Signed-off-by: Heikki Krogerus Signed-off-by: Felipe Balbi

usb: common: of_usb_get_dr_mode to usb_get_dr_mode

2015-09-27T15:54:31Z

By using the unified device property interface, the function can be made available for all platforms and not just the ones using DT. Signed-off-by: Heikki Krogerus Signed-off-by: Felipe Balbi

usb: dwc3: support for pinctrl state change during system sleep

2015-09-27T15:54:31Z

Add support for USB DRVVBUS pinctrl state change during suspend/resume. This helps is conserving power during system sleep. Signed-off-by: Sekhar Nori Signed-off-by: Felipe Balbi

usb: dwc3: Add frame length adjustment quirk

2015-09-27T15:54:31Z

Add adjust_frame_length_quirk for writing to fladj register which adjusts (micro)frame length to value provided by "snps,quirk-frame-length-adjustment" property thus avoiding USB 2.0 devices to time-out over a longer run Signed-off-by: Nikhil Badola Signed-off-by: Felipe Balbi

usb: dwc3: core: remove unnecessary dev_warn()

2015-07-29T14:59:19Z

When a SoC supports both PHY interfaces but doesn't define HSPHY in DT/pdata, we will get an unnecessary dev_warn() which can mislead users into thinking that they're missing something. Instead, let's just silently rely on a correct default. If the HW default is wrong, then HSPHY is required and USB won't work, this will be motivation enough for engineers to patch their way into a working setup.

usb: dwc3: core: avoid NULL pointer dereference

2015-07-06T17:34:08Z

commit 3e10a2ce98d1 ("usb: dwc3: add hsphy_interface property") introduced a possible NULL pointer dereference because dwc->hsphy_interface can be NULL. In order to fix it, all we have to do is guard strncmp() against a NULL argument.
