USB: core: add endpoint-blacklist quirk

2020-02-28T15:38:46Z

commit 73f8bda9b5dc1c69df2bc55c0cbb24461a6391a9 upstream. Add a new device quirk that can be used to blacklist endpoints. Since commit 3e4f8e21c4f2 ("USB: core: fix check for duplicate endpoints") USB core ignores any duplicate endpoints found during descriptor parsing. In order to handle devices where the first interfaces with duplicate endpoints are the ones that should have their endpoints ignored, we need to add a blacklist.

USB: serial: ir-usb: fix link-speed handling

2020-02-01T09:37:01Z

commit 17a0184ca17e288decdca8b2841531e34d49285f upstream. Commit e0d795e4f36c ("usb: irda: cleanup on ir-usb module") added a USB IrDA header with common defines, but mistakingly switched to using the class-descriptor baud-rate bitmask values for the outbound header. This broke link-speed handling for rates above 9600 baud, but a device would also be able to operate at the default 9600 baud until a link-speed request was issued (e.g. using the TCGETS ioctl).

usb: typec: tcpm: Notify the tcpc to start connection-detection for SRPs

2020-01-27T13:50:40Z

[ Upstream commit 7893f9e1c26d1f9ea02622902ee671de45ad377b ] Some tcpc device-drivers need to explicitly be told to watch for connection events, otherwise the tcpc will not generate any TCPM_CC_EVENTs and devices being plugged into the Type-C port will not be noticed. For dual-role ports tcpm_start_drp_toggling() is used to tell the tcpc to watch for connection events. Sofar we lack a similar callback to the tcpc for single-role ports. With some tcpc-s such as the fusb302 this means no TCPM_CC_EVENTs will be generated when the port is configured as a single-role port. This commit renames start_drp_toggling to start_toggling and since the device-properties are parsed by the tcpm-core, adds a port_type parameter to the start_toggling callback so that the tcpc_dev driver knows the port-type and can act accordingly when it starts toggling. The new start_toggling callback now always gets called if defined, instead of only being called for DRP ports. To avoid this causing undesirable functional changes all existing start_drp_toggling implementations are not only renamed to start_toggling, but also get a port_type check added and return -EOPNOTSUPP when port_type is not DRP.

usb: typec: tcpm: Do not disconnect link for self powered devices

2019-01-26T08:32:34Z

[ Upstream commit 23b5f73266e59a598c1e5dd435d87651b5a7626b ] During HARD_RESET the data link is disconnected. For self powered device, the spec is advising against doing that. >From USB_PD_R3_0 7.1.5 Response to Hard Resets Device operation during and after a Hard Reset is defined as follows: Self-powered devices Should Not disconnect from USB during a Hard Reset (see Section 9.1.2). Bus powered devices will disconnect from USB during a Hard Reset due to the loss of their power source. Tackle this by letting TCPM know whether the device is self or bus powered. This overcomes unnecessary port disconnections from hard reset. Also, speeds up the enumeration time when connected to Type-A ports.

USB: Wait for extra delay time after USB_PORT_FEAT_RESET for quirky hub

ALSA: usb-audio: Initial Power Domain support

2018-07-31T13:01:22Z

Thee USB Audio Class 3 (UAC3) introduces Power Domains as a new feature to let a host turn individual parts of an audio function to different power states via USB requests. This lets the device get to know a bit amore about what the host is up to in order to optimize power consumption efficiently. The Power Domains are optional for UAC3 configuration but all UAC3 devices shall include at least one BADD configuration where the support for Power Domains is compulsory. This patch adds a set of features/helpers to parse these power domains and change their status. Signed-off-by: Jorge Sanjuan Signed-off-by: Takashi Iwai

ALSA: usb-audio: Add support for Processing Units in UAC3

2018-07-16T14:35:34Z

This patch adds support for the Processig Units defined in the UAC3 spec. The main difference with the previous specs is the lack of on/off switches in the controls for these units and the addiction of the new Multi Function Processing Unit. The current version of the UAC3 spec doesn't define any useful controls for the new Multi Function Processing Unit so no control will get created once this unit is parsed.
