usb: typec: ucsi: Add debugfs for ucsi commands
Add support for UCSI commands through the following debugfs:
# /sys/kernel/debug/usb/ucsi/$UCSI_DEVICE/command
# /sys/kernel/debug/usb/ucsi/$UCSI_
usb: typec: ucsi: Add debugfs for ucsi commands
Add support for UCSI commands through the following debugfs:
# /sys/kernel/debug/usb/ucsi/$UCSI_DEVICE/command
# /sys/kernel/debug/usb/ucsi/$UCSI_DEVICE/response
Eg: To execute UCSI GetCapabilities:
# echo 0x6 > /sys/kernel/debug/usb/ucsi/<ucsi device>/command
Then read the result,
# cat /sys/kernel/debug/usb/ucsi/<ucsi device>/response
0x02000320000000020000ff0400000445
UCSI command will be written into the command file and the
response for the command can be viewed under the response file.
