[PATCH v4 1/2] i2c: buses: add i2c bus driver for NVIDIA GPU

Latest NVIDIA GPU card has USB Type-C interface. There is a Type-C controller which can be accessed over I2C. This driver adds I2C bus driver to communicate with Type-C controller. I2C client driver will be part of USB Type-C UCSI driver. Signed-off-by: Ajay Gupta --- Changes from v1 -> v2

[PATCH v4 2/2] usb: typec: ucsi: add support for Cypress CCGx

Latest NVIDIA GPU cards have a Cypress CCGx Type-C controller over I2C interface. This UCSI I2C driver uses I2C bus driver interface for communicating with Type-C controller. Signed-off-by: Ajay Gupta --- Changes from v1 -> v2 Fixed identation in drivers/usb/typec/ucsi/Kconfig Changes

A few questions about gadgetfs

Hi Alan, I have a few questions about gadgetfs. According to documentation usb_gadget_driver->setup "queues a response to ep0, or returns negative to stall". Do I understand correctly, that "stall" in this case means "retry the same request later" and it's unrelated to the STALL USB packet? Is

A question about 'lsusb'

Based on my (limited) understanding if I were to disable udev, the userspace should not be able to enumerate/interact with any newly connected device since udev handles uevents generated by kernel. (right?) So as a test, I disabled systemd-udevd and then plugged in a flash drive. I disabled

Hello. FYI. I made a progress on this, but no solution yet. >The smartphone does use HNP, it is not iPhone Carplay, correct? At this point, I am trying to see original HNP behavior between two pocketbeagles. (After seeing it works, I plan to replace B-device with a phone, and so customization

[REGRESSION, BISECTED] cdc-acm: problem with MCP2200

Hello, I am using USB-UART optical serial converter [1], which is based on MCP2200. It is connected to my RaspberryPi and the other side is connected to my remeha gas boiller. My problems starts with this commit: commit a81cf9799ad7299b03a4dff020d9685f9ac5f3e0 Author: Oliver Neukum Date:

[PATCH] Revert "cdc-acm: implement put_char() and flush_chars()"

This reverts commit a81cf9799ad7299b03a4dff020d9685f9ac5f3e0. The patch causes a regression, which I cannot find the reason for. So let's revert for now, as a revert hurts only performance. I was trying to resolve the problem with Oliver but we don't get any conclusion for 5 months, so I am now
