Implement active cable VDM support for SOP' according to the DisplayPort
Alt Mode 2.0 specification.

When probing the DisplayPort driver, the state machine will transition to
Enter Mode on SOP' if an active cable altmode is detected. The SVDM flow
is as followed:
    (1) Enter Mode     SOP'
    (2) Enter Mode     SOP
    (3) Status Update  SOP
    (4) Configure      SOP'
    (5) Configure      SOP

Status Update on SOP' after Enter Mode is optional and not implemented for
now. When exiting the alt mode, send Exit Mode over SOP' after SOP.

Should an altmode vdm fail on SOP', the DisplayPort driver will drop its
reference to the plug and attempt to continue in SOP operation.

Add new dp_state enums DP_STATE_ENTER_PRIME, DP_STATE_CONFIGURE_PRIME, and
DP_STATE_EXIT_PRIME. dp_altmode adds typec_displayport_data for the cable
plug to store the plug configuration and adds a typec_altmode reference
for the cable plug.

dp_altmode_configure takes the cable pin assignment capabilities into
account when deciding on pin configuration. dp_altmode_configure_vdm_cable
sends the configure message on SOP'.

dp_altmode_activate now attempts to enter on SOP' if applicable, and will
attempt to enter on SOP on failure.

dp_cable_altmode_vdm handles VDMs passed to the DisplayPort driver from
the tcpm.

svdm_consume_svids and svdm_consume_modes take the received SVDM's SOP*

Add data message handling and Discover Identity SVDM over SOP'

This patch contains the following changes:
    1. pd_vdo
Add VDO indices for active and passive cables, documentation to reflect
expected number of objects depending on PD Revision, and macro to indicate
port parter is data host capable.
    2. tcpm
Add typec_cable and typec_plug to tcpm_port to maintain cable and plug
information. tcpm_port also adds send_discover_prime to indicate that
Discover Identity should be sent out of the ready state.

tcpm_queue_vdm and tcpm_send_vdm now take the SOP* type when transmitting
messages. tcpm_handle_vdm_request and tcpm_pd_svdm also use the SOP* type.
tcpm_pd_svdm handles Discover Identity messages for SOP and SOP'. In the
SOP case, the port uses tcpm_attempt_vconn_swap_discovery to determine if
a Vconn swap is needed for cable communication. Otherwise, the port will
send Discover Identity on SOP' if it can, or default to Discover SVIDs.

svdm_consume_identity_sop_prime consumes the result of Discover Identity
on SOP'. It fills out cable identity and description, and it registers
the cable. The SOP' plug is registered as well.

The VDM state machine is adjusted to construct messages based on the SOP*
type. If a transmission error occurs after the max number of retries for
Discover Identity over SOP', then the port will send Discover SVIDs over
SOP.

VCONN_SWAP_TURN_ON_VCONN now moves to a new state,

tcpm_can_communicate_sop_prime is added as a helper to determine whether
the port is capable of communicating over SOP' at a given moment. Being

Some USB controller drivers call otg_set_vbus when entering host or
device mode. Implement this callback so that VBUS can be turned on and
off automatically. This is especially useful when there is no property
for a VBUS supply in the controller's binding.

This results in a change in semantics of the vbus_draw regulator.
Whereas before it represented the VBUS supplied by an A-Device when we
acted as a B-Device, now it represents an internal VBUS source.
Accordingly, we no longer set the current limit or enable/disable the
bus from nop_gpio_vbus_thread. Because this supply was never initialized
before the previous commit, there should be no change in behavior.

In Realtek SoC, the parameter of usb phy is designed to can dynamic
tuning base on port status. Therefore, add a notify callback of generic
phy driver when usb device connect and disconnect 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 connection 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.

Generic phy driver in usb core framework does not support device connect
and disconnect notifications. Therefore, we add an api to notify phy
the connection changes.

Additionally, the generic phy only specifies primary_hcd in the original
design. Added specific "usb2-phy" on primary_hcd and "usb3-phy" on

With the Cypress CCGx Type-C controller the following error is
sometimes observed on boot:
[   16.087147] ucsi_ccg 1-0008: failed to reset PPM!
[   16.087319] ucsi_ccg 1-0008: PPM init failed (-110)

When the above timeout occurs the following happens:
1. The function ucsi_reset_ppm() is called to reset UCSI controller.
   This function performs an async write to start reset and then
   polls for completion.
2. An interrupt occurs when the reset completes. In the interrupt
   handler, the OPM field in the INTR_REG is cleared and this clears
   the CCI data in the PPM. Hence, the reset completion status is
   cleared.
3. The function ucsi_reset_ppm() continues to poll for the reset
   completion, but has missed the reset completion event and
   eventually timeouts.

In this patch, we store CCI when handling the interrupt and make
reading after async write gets the correct value.

To align with the CCGx UCSI interface guide, this patch updates the
driver to copy CCI and MESSAGE_IN before they are reset when UCSI
interrupt acknowledged.

When a new command is sent, the driver will clear the old CCI to avoid
ucsi_ccg_read() getting wrong CCI after ucsi_ccg_async_write() when
the UCSI interrupt is not handled.

Finally, acking the UCSI_READ_INT interrupt before calling complete()
in ISR to ensure that the ucsi_ccg_sync_write() would wait for the
interrupt handling to complete.

Pull more bcachefs updates from Kent Overstreet:
 "Some fixes, Some refactoring, some minor features:

   - Assorted prep work for disk space accounting rewrite

   - BTREE_TRIGGER_ATOMIC: after combining our trigger callbacks, this
     makes our trigger context more explicit

   - A few fixes to avoid excessive transaction restarts on
     multithreaded workloads: fstests (in addition to ktest tests) are
     now checking slowpath counters, and that's shaking out a few bugs

   - Assorted tracepoint improvements

   - Starting to break up bcachefs_format.h and move on disk types so
     they're with the code they belong to; this will make room to start
     documenting the on disk format better.

   - A few minor fixes"

Pull timer updates from Thomas Gleixner:
 "Updates for time and clocksources:

   - A fix for the idle and iowait time accounting vs CPU hotplug.

     The time is reset on CPU hotplug which makes the accumulated
     systemwide time jump backwards.

   - Assorted fixes and improvements for clocksource/event drivers"
