usb: Add base USB MCTP definitions

2025-02-22T00:45:21+00:00

Upcoming changes will add a USB host (and later gadget) driver for the
MCTP-over-USB protocol. Add a header that provides common definitions
for protocol support: the packet header format and a few framing
definitions. Add a define for the MCTP class code, as per
https://usb.org/defined-class-codes.

r8152: add vendor/device ID pair for Dell Alienware AW1022z

2025-02-11T01:57:35+00:00

The Dell AW1022z is an RTL8156B based 2.5G Ethernet controller.

Add the vendor and product ID values to the driver. This makes Ethernet
work with the adapter.

usb: musb: Constify struct musb_fifo_cfg

2025-02-03T15:29:53+00:00

'struct musb_fifo_cfg' are not modified in these drivers.

Constifying these structures moves some data to a read-only section, so
increase overall security.

On a x86_64, with allmodconfig, as an example:
Before:
======
   text	   data	    bss	    dec	    hex	filename
  64381	   5537	    202	  70120	  111e8	drivers/usb/musb/musb_core.o

After:
=====

usb: typec: tcpci: Prevent Sink disconnection before vPpsShutdown in SPR PPS

2025-01-17T11:40:20+00:00

The Source can drop its output voltage to the minimum of the requested
PPS APDO voltage range when it is in Current Limit Mode. If this voltage
falls within the range of vPpsShutdown, the Source initiates a Hard
Reset and discharges Vbus. However, currently the Sink may disconnect
before the voltage reaches vPpsShutdown, leading to unexpected behavior.

Prevent premature disconnection by setting the Sink's disconnect
threshold to the minimum vPpsShutdown value. Additionally, consider the
voltage drop due to IR drop when calculating the appropriate threshold.
This ensures a robust and reliable interaction between the Source and
Sink during SPR PPS Current Limit Mode operation.

usb: typec: Make active on port altmode writable

2024-12-24T07:56:05+00:00

The active property of port altmode should be writable (to prevent or
allow partner altmodes from entering) and needs to be part of
typec_altmode_desc so we can initialize the port to an inactive state if
desired.

usb: typec: tcpm: Add new AMS for Get_Revision response

2024-12-24T07:56:04+00:00

This commit adds a new AMS for responding to a "Get_Revision" request.
Revision message consists of the following fields:

 +----------------------------------------------------+
 |         Header             |         RMDO          |
 |  No. of data objects = 1   |                       |
 +----------------------------------------------------+

 While RMDO consists of:
  * B31..28     Revision Major
  * B27..24     Revision Minor
  * B23..20     Version Major
  * B19..16     Version Minor
  * B15..0      Reserved, shall be set to zero.

As per the PD spec ("8.3.3.16.2.1 PR_Give_Revision State"), a request is
only expected when an explicit contract is established and the port is
in ready state. This AMS is only supported for PD >= 3.0.
