If memory accesses by the Tegra XUSB controller are translated through the SMMU (System MMU), the hardware may continue accessing memory even after the SMMU translations have been disabled during the shutdown process and this can in turn cause unpredictable crashes. Fix this by adding a shutdown implementation that ensures the hardware is turned off during system reboot or shutdown. Signed-off-by:

This patch allows users to set up MIDI 1.0 ports more flexibly. Namely, instead of the fixed mapping only from FB 0, now multiple block definitions are applied to build up the MIDI 1.0 mapping. The each block config has midi1_first_group and midi1_num_groups attributes, and those specify which Groups are used for MIDI 1.0. Those fields must be within the UMP Groups defined in the block itself. Signed-off-by:

Add a new ALSA control element to watch the current operation mode (MIDI 1.0 or MIDI 2.0). It's a read-only control that reflects the current value of altsetting, and 0 means unused, 1 for MIDI 1.0 (altset 0) and 2 for MIDI 2.0 (altset 1). Signed-off-by:

This patch extends MIDI 2.0 function driver to add more proper support for MIDI 1.0 interface. Before this patch, the driver only exposes the USB descriptor of a MIDI 1.0 interface in altset 0 while no actual I/O is running for it. This patch enables the actual I/O for the altset 0; the backend UMP rawmidi is translated from/to the MIDI 1.0 USB commands. For converting to USB MIDI 1.0 data protocol, a helper function is copied from the existing f_midi driver, in addition to a few other UMP Core helper functions. For the MIDI 1.0 OUT (that is, input for gadget), the incoming USB MIDI 1.0 packet is translated to UMP packets via UMP Core helper, and tossed to the attached UMP rawmidi. It's a relatively straightforward. OTOH, for MIDI 1.0 IN (i.e. output for gadget), it's a bit more complex: we need to convert a source UMP packet once to the standard MIDI 1.0 byte stream, and convert it again to USB MIDI 1.0 packets, then send them out.

This patch extends MIDI 2.0 function driver to deal with more MIDI1 Jacks depending on the given Block configuration. For MIDI 1.0, we take the configuration given in Function Block 0, and create MIDI Jacks and Endpoints depending on the definition there. That is, when more UMP Groups are defined in the Block 0, the corresponding MIDI1 Jacks will be created. Signed-off-by:

This patch adds the support of configfs to MIDI 2.0 function driver for users to allow configuring the UMP Endpoint and Function Blocks more flexibly. The configuration is in a tree form. The top-most contains some card-level configurations. UMP Endpoints are defined in subdirectories (ep.0, ep.1, etc) that contain Endpoint-specific configurations such as ep_name, etc. And, UMP Function Blocks are defined in the subdirectories (block.0, block.1, etc) under EP subdirectory. As default, the driver creates a single UMP Endpoint (ep.0) and a single Function Block (block.0) to work in a minimalistic manner. User can modify those attributes freely to fit with the demands. When multiple Function Blocks are required, user can create another directory as block.1, block.2, and so on (up to block.31). A block.* directory can be deleted dynamically, too. A caveat is that the block number has to be continuous. Similarly, when multiple UMP Endpoints are required, user can create another directory as ep.1, ep.2, up to ep.3. Also, some driver behavior can be controlled in the card top-level configs. e.g. you can pass process_ump=0 to disable the processing of UMP Stream messages. This would be equivalent with the older MIDI 2.0 spec that doesn't support UMP v1.1 features. The configfs interface checks upper- / lower-bound of input values, and more sanity checks are performed at binding. Attributes can't be changed any longer once when the instance is linked to UDC.

This patch adds the support for USB MIDI 2.0 gadget function driver. The driver emulates a USB MIDI 2.0 interface with one or more UMP Endpoints, where each of UMP Endpoint is a pair of MIDI Endpoints for handling MIDI 2.0 UMP packets. When the function driver is bound, the driver creates an ALSA card object with UMP rawmidi devices. This is a kind of loop-back where the incoming and upcoming UMP packets from/to the MIDI 2.0 UMP Endpoints are transferred as-is. In addition, legacy (MIDI 1.0) rawmidi devices are created, so that legacy applications can work in the gadget side, too. When a USB MIDI 2.0 gadget interface appears, the connected host can use it with the snd-usb-audio driver where MIDI 2.0 support is enabled. Both gadget and connected hosts will have the similar UMP Endpoint and Function Block (or Group Terminal Block) information. Slight differences are the direction and UI-hint bits; it's due to the nature of gadget driver, and the input/output direction is swapped in both sides (the input for gadget is the output for host, and vice versa). The driver supports the brand-new UMP v1.1 feature, including the UMP Stream message handling for providing UMP Endpoint and Function Block information as well as dealing with the MIDI protocol switch. The driver responds to UMP Stream messages by itself. OTOH, MIDI-CI message handling isn't implemented in the kernel driver; it should be processed in the user-space through the loopback UMP device. As of this patch, the whole configuration is fixed, providing only one bidirectional UMP Endpoint containing a single FB/GTB with a single UMP Group. The configuration will be dynamically changeable in the following patches. The traditional MIDI 1.0 is still provided in the altset 0 (which is mandatory per spec). But it's only about the configuration, and no actual I/O will be running for the altset 0 as of this patch. The proper support MIDI 1.0 altset will follow in later patches, too. Signed-off-by:

In Realtek SoC, the parameter of usb phy is designed to can dynamic tuning base on port status. Therefore, add a notify callback of phy driver when usb port status change. The Realtek phy driver is designed to dynamically adjust disconnection level and calibrate phy parameters. When the device connected bit changes and when the disconnected bit changes, do port status change notification: Check if portstatus is USB_PORT_STAT_CONNECTION and portchange is USB_PORT_STAT_C_CONNECTION. 1. The device is connected, the driver lowers the disconnection level and calibrates the phy parameters. 2. The device disconnects, the driver increases the disconnect level and calibrates the phy parameters. When controller to notify connect that device is already ready. If we adjust the disconnection level in notify_connect, the disconnect may have been triggered at this stage. So we need to change that as early as possible. The status change of connection is before port reset. Therefore, we add an api to notify phy the port status changes. In this stage, the device is not port enable, and it will not trigger disconnection. Signed-off-by:

The function mxs_phy_is_otg_host() will return true if OTG_ID_VALUE is 0 at USBPHY_CTRL register. However, OTG_ID_VALUE will not reflect the real state if the ID pin is float, such as Host-only or Type-C cases. The value of OTG_ID_VALUE is always 1 which means device mode. This patch will fix the issue by judging the current mode based on last_event. The controller will update last_event in time.

The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes. Acked-by:

The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Eventually after all drivers are converted, .remove_new() is renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant. Signed-off-by:

Now that the driver core allows for struct class to be in read-only memory, remove the usb_class structure and create the usbmisc_class const class structure declared at build time which places it into read-only memory, instead of having it to be dynamically allocated at load time. Additionally, now we register usb class at startup and unregister it when shutting down, so we don't have to count uses of the class. Therefore we don't need the 'usb_class' structure anymore. Due to this fact, remove all static functions related to class initialization and deinitialization. We can't use them in 'usb.c' since they are static and we don't really need them anymore. Since we have to register the class in usb_init function in 'usb.c' and use it in 'file.c' as well, declare the usbmisc_class structure as 'export' in the 'usb.h' file. Debatable moment: the class registration and unregistration functions could be extracted to the 'file.c'. I think we don't want to do this since it would be one-line functions. They would make the code paths more confusing and add calling overhead. Suggested-by:
