It's dangerous to use empty code define. Furthermore it lead to the following warning: "suggest braces around empty body in an « else » statement" So let's replace emptyness by "do {} while(0)" Furthermore, as suggested by Joe Perches, rename the macro to INCR.

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:

USB Type-C class driver now expects the muxes to be always assigned to the ports and not controllers, so the connections for the mux and fusb302 can be removed. 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:

Adding a connection for the DisplayPort alternate mode. PI3USB30532 is used for muxing the port to DisplayPort on CHT platforms. The connection allows the alternate mode device to get handle to the mux, and therefore make it possible to use the USB Type-C connector as DisplayPort. 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.

R-Car Gen3 needs to enable clocks of both host and peripheral. Since [eo]hci-platform disables the reset(s) when the drivers are removed, renesas_usbhs driver doesn't work correctly. To fix this issue, this patch adds multiple clocks management on this renesas_usbhs driver. Signed-off-by:

R-Car Gen3 needs to deassert resets of both host and peripheral. Since [eo]hci-platform is possible to assert the reset(s) when the probing failed, renesas_usbhs driver doesn't work correctly regardless of finished probing.

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.

Add ioctl USBTMC_IOCTL_API_VERSION to get current API version of usbtmc driver. This is to allow an instrument library to determine whether the driver API is compatible with the implementation. The API may change in future versions. Therefore the macro USBTMC_API_VERSION should be incremented when changing tmc.h with new flags, ioctls or when changing a significant behavior of the driver.

Insert a sleep of 50 ms between subsequent CHECK_ABORT_BULK_OUT_STATUS control requests to avoid stressing the instrument with repeated requests.

Add parameter 'tag' to function usbtmc_ioctl_abort_bulk_in_tag() for future versions. Remove calculation of max_size (=wMaxPacketSize) and wrong condition (actual == max_size) in while loop. An abort operation should always flush the complete Bulk-IN until a short packet is received. Return error code ENOMSG when transfer (specified by given tag) is not in progress and device returns code USBTMC_STATUS_TRANSFER_NOT_IN_PROGRESS. Use USBTMC_BUFSIZE (4k) instead of USBTMC_SIZE_IOBUFFER (2k). Using USBTMC_SIZE_IOBUFFER is deprecated. Use common macro USB_CTRL_GET_TIMEOUT instead of USBTMC_TIMEOUT. Check only bit 0 (field bmAbortBulkIn) of the CHECK_ABORT_BULK_IN_STATUS response, since other bits are reserved and can change in future versions. Signed-off-by:

Remove calculation of max_size (=wMaxPacketSize) and wrong condition (actual == max_size) in while loop. A device clear should always flush the complete Bulk-IN FIFO. Insert a sleep of 50 ms between subsequent CHECK_CLEAR_STATUS control requests to avoid stressing the instrument with repeated requests. Some instruments need time to cleanup internal I/O buffers. Polling and nonbraked requests slow down the response time of devices. Use USBTMC_BUFSIZE (4k) instead of USBTMC_SIZE_IOBUFFER (2k). Using USBTMC_SIZE_IOBUFFER is deprecated. Check only bit 0 (field bmClear) of the CHECK_CLEAR_STATUS response, since other bits are reserved and can change in future versions. Signed-off-by:
