Fix uninitialized symbol 'actual' in function usbtmc_read. When symbol 'actual' is not initialized and usb_bulk_msg() fails, the subsequent kernel debug message shows a random value. Signed-off-by:

This patch adds support for R-Car E3. This SoC needs to release the PLL reset by the UGCTRL register like R-Car D3. So, this patch adds a usbhs_of_match entry for this SoC with "USBHS_TYPE_RCAR_GEN3_WITH_PLL". Signed-off-by:

This reverts commit 8ada211d. R-Car D3 can use OTG mode in fact. So, the commit doesn't need anymore. In other words, like other R-Car Gen3 SoCs, R-Car D3 can change the mode by using the phy-rcar-gen3-usb2 driver. Signed-off-by:

After commit 1cbd53c8 ("usb: core: introduce per-port over-current counters") usb ports expose a sysfs value 'over_current_count' to user space. This value on its own is not very useful as it requires manual polling. As a solution, fire a udev event from the usb hub device that specifies the values 'OVER_CURRENT_PORT' and 'OVER_CURRENT_COUNT' that indicate the path of the usb port where the over-current event occurred and the value of 'over_current_count' in sysfs. Additionally, call sysfs_notify() so the sysfs value supports poll(). Signed-off-by:

When the controller is configured for a fixed power role (Source only or Sink only), attach does not proceed within the TCPM state machine as there is no CC event generated by this driver to update the CC line status. To rectify this, when CC is configured as Source or Sink we now make use of the hardware's automatic fixed Source or Sink toggling mechanism, which detects attaches in the same way as for DRP toggling. In this way the result of toggling is handled in the same way by the 'fusb302_handle_togdone()' function, and CC events are generated as expected for TCPM allowing a contract to be established.

When USB bus host controller root hub resumes from autosuspend, it immediately tries to enter auto-suspend, but there can be a scenario when root hub is resuming its usb2 ports, in that particular case USB host controller auto suspend fails since it is busy to resuming its usb2 ports. This makes multiple failed cycles of auto-suspend until all usb2 ports of host controller root hub do not resume. This patch uses USB core framework usb_hcd_start_port_resume, usb_hcd_end_port_resume API's in order to autoresume/autosuspend root hub properly. Signed-off-by:

The XUSB firmware header is in little endian byte order, so make the fields __le32 and __le16 instead of u32 and u16 to avoid warnings from sparse when the fields are used with the endian-aware __le32_to_cpu() and __le16_to_cpu() accessors, respectively. Signed-off-by:

The xhci controller on Alpine and Titan Ridge keeps the whole thunderbolt awake if the host controller is not allowed tp sleep. This is the case even if no USB devices are connected to the host. Because of this bigger impact, allow runtime pm as default for these xhci controllers in the driver. Signed-off-by:

Use soft retry to recover from a USB Transaction Errors that are caused by temporary error conditions. The USB device is not aware that the xHC has halted the endpoint, and will be waiting for another retry A Soft Retry perform additional retries and recover from an error which has caused the xHC to halt an endpoint. Soft retry has some limitations: Soft Retry attempts shall not be performed on Isoch endpoints Soft Retry attempts shall not be performed if the device is behind a TT in a HS Hub Software shall limit the number of unsuccessful Soft Retry attempts to prevent an infinite loop. For more details on Soft retry see xhci specs 4.6.8.1 Signed-off-by:

The debugfs needs to be initialized as the last step in probe in this case. The struct dentry *rootdir can't be pointing to anything unless driver probe really finishes successfully. It is also not necessary to clear the i2c clientdata if the probe fails, so removing the extra label used for that. Acked-by:

It is not possible to use the parent of the port device when requesting mux handles as the parent may be a multiport USB Type-C or PD controller. The muxes must be assigned to the ports, not the controllers. This will also move the requesting of the muxes after the port device is initialized. Acked-by:

Assigning the mux to the USB Type-C port on top of fusb302. That will prepare this driver for the change in the USB Type-C class code, where the class driver will assume the muxes to be always assigned to the ports and not the controllers. Once the USB Type-C class driver has been updated, the connections between the mux and fusb302 can be dropped. Acked-by:

There is code in the .remove() hook to handle the drvdata being NULL, for good reasons: it is never set, so it will always be NULL. As I moved code around, static checkers start complaining. Instead of this, make sure to always set it on successful probe so we can always dereference it on the remove path. Use the platform_device_[set|get]_drvdata() since this is a platform device.

USB audio class 3.0 specification introduced many significant changes like - new power domains, support for LPM/L1 - new cluster descriptor - new high capability and class-specific string descriptors - BADD profiles - ... and many other things (check spec from link below: http://www.usb.org/developers/docs/devclass_docs/USB_Audio_v3.0.zip) Now that UAC3 is supported in linux, choose UAC3 configuration for audio if the device supports it. Selecting this configuration will enable the system to save power by leveraging the new power domains and LPM L1 capability and also support new codec types and data formats for consumer audio applications.
