commit 23e26d0577535f5ffe4ff8ed6d06e009553c0bca upstream.

The patch addresses the compliance test failures while running  TDA
2.3.1.1 and  TDA 2.3.1.2 of the "PD Communications Engine USB PD
Compliance MOI" test plan published in https://www.usb.org/usbc.
For a product to be Type-C compliant, it's expected that these tests
are run on usb.org certified Type-C compliance tester as mentioned in
https://www.usb.org/usbc.

While the purpose of TDA 2.3.1.1 and  TDA 2.3.1.2 is to verify that
the static and dynamic electrical capabilities of a Source meet the
requirements for each PDO offered,  while doing so, the tests also
monitor that the timing of the VBUS waveform versus the messages meets
the requirements for Hard Reset defined in PROT-PROC-HR-TSTR as
mentioned in step 11 of TDA.2.3.1.1 and step 15 of TDA.2.3.1.2.

TDB.2.2.13.1: PROT-PROC-HR-TSTR Procedure and Checks for Tester
Originated Hard Reset
Purpose: To perform the appropriate protocol checks relating to any
circumstance in which the Hard Reset signal is sent by the Tester.

UUT is behaving as source:
The Tester sends a Hard Reset signal.
1. Check VBUS stays within present valid voltage range for
tPSHardReset min (25ms) after last bit of Hard Reset signal.
[PROT_PROC_HR_TSTR_1]
2. Check that VBUS starts to fall below present valid voltage range by
tPSHardReset max (35ms). [PROT_PROC_HR_TSTR_2]
3. Check that VBUS reaches vSafe0V within tSafe0v max (650 ms).
[PROT_PROC_HR_TSTR_3]
4. Check that VBUS starts rising to vSafe5V after a delay of
tSrcRecover (0.66s - 1s) from reaching vSafe0V. [PROT_PROC_HR_TSTR_4]
5. Check that VBUS reaches vSafe5V within tSrcTurnOn max (275ms) of
rising above vSafe0v max (0.8V). [PROT_PROC_HR_TSTR_5] Power Delivery
Compliance Plan 139 6. Check that Source Capabilities are finished
sending within tFirstSourceCap max (250ms) of VBUS reaching vSafe5v
min. [PROT_PROC_HR_TSTR_6].

This is in line with 7.1.5 Response to Hard Resets of the USB Power
Delivery Specification Revision 3.0, Version 1.2,
"Hard Reset Signaling indicates a communication failure has occurred
and the Source Shall stop driving VCONN, Shall remove Rp from the
VCONN pin and Shall drive VBUS to vSafe0V as shown in Figure 7-9. The
USB connection May reset during a Hard Reset since the VBUS voltage
will be less than vSafe5V for an extended period of time. After
establishing the vSafe0V voltage condition on VBUS, the Source Shall
wait tSrcRecover before re-applying VCONN and restoring VBUS to
vSafe5V. A Source Shall conform to the VCONN timing as specified in
[USB Type-C 1.3]."

With the above guidelines from the spec in mind, TCPM does not turn
off VCONN while entering SRC_HARD_RESET_VBUS_OFF. The patch makes TCPM
turn off VCONN while entering SRC_HARD_RESET_VBUS_OFF and turn it back
on while entering SRC_HARD_RESET_VBUS_ON along with vbus instead of
having VCONN on through hardreset.

Also, the spec clearly states that "After establishing the vSafe0V
voltage condition on VBUS",  the Source Shall wait tSrcRecover before
re-applying VCONN and restoring VBUS to vSafe5V.
TCPM does not conform to this requirement. If the TCPC driver calls
tcpm_vbus_change with vbus off signal, TCPM right away enters
SRC_HARD_RESET_VBUS_ON without waiting for tSrcRecover.
For TCPC's which are buggy/does not call tcpm_vbus_change, TCPM
assumes that the vsafe0v is instantaneous as TCPM only waits
tSrcRecover instead of waiting for tSafe0v + tSrcRecover.
This patch also fixes this behavior by making sure that TCPM waits for
tSrcRecover before transitioning into SRC_HARD_RESET_VBUS_ON when
tcpm_vbus_change is called by TCPC.
When TCPC does not call tcpm_vbus_change, TCPM assumes the worst case
i.e.  tSafe0v + tSrcRecover before transitioning into
SRC_HARD_RESET_VBUS_ON.

Commit 081da1325d35 ("usb: typec: ucsi: displayport: Fix a potential race
during registration") made the ucsi code hold con-&gt;lock in
ucsi_register_displayport(). But we really don't want any interactions
with the connector to run before the port-registration process is fully
complete.

This commit moves the taking of con-&gt;lock from ucsi_register_displayport()
into ucsi_register_port() to achieve this.

commit 25794e3079d2a98547b6bf5764ef0240aa89b798 upstream.

The ppm_lock really only needs to be hold during 2 functions:
ucsi_reset_ppm() and ucsi_run_command().

Push the taking of the lock down into these 2 functions, renaming
ucsi_run_command() to ucsi_send_command() which was an existing
wrapper already taking the lock for its callers.

This simplifies things for the callers and removes the difference
between ucsi_send_command() and ucsi_run_command() which has led
to various locking bugs in the past.

commit 7e90057f125c8c852940b848e06e7a72f050fc6f upstream.

Fix 2 unlocked ucsi_run_command calls:

1. ucsi_handle_connector_change() contains one ucsi_send_command() call,
which takes the ppm_lock for it; and one ucsi_run_command() call which
relies on the caller have taking the ppm_lock.
ucsi_handle_connector_change() does not take the lock, so the
second (ucsi_run_command) calls should also be ucsi_send_command().

2. ucsi_get_pdos() gets called from ucsi_handle_connector_change() which
does not hold the ppm_lock, so it also must use ucsi_send_command().

This commit also adds a WARN_ON(!mutex_is_locked(&amp;ucsi-&gt;ppm_lock)); to
ucsi_run_command() to avoid similar problems getting re-introduced in
the future.

commit 0ff0705a2ef2929e9326c95df48bdbebb0dafaad upstream.

Lockdep reports an AB BA lock inversion between ucsi_init() and
ucsi_handle_connector_change():

AB order:

1. ucsi_init takes ucsi-&gt;ppm_lock (it runs with that locked for the
   duration of the function)
2. usci_init eventually end up calling ucsi_register_displayport,
   which takes ucsi_connector-&gt;lock

BA order:

1. ucsi_handle_connector_change work is started, takes ucsi_connector-&gt;lock
2. ucsi_handle_connector_change calls ucsi_send_command which takes
   ucsi-&gt;ppm_lock

The ppm_lock really only needs to be hold during 2 functions:
ucsi_reset_ppm() and ucsi_run_command().

This commit fixes the AB BA lock inversion by making ucsi_init drop the
ucsi-&gt;ppm_lock before it starts registering ports; and replacing any
ucsi_run_command() calls after this point with ucsi_send_command()
(which is a wrapper around run_command taking the lock while handling
the command).

Some of the replacing of ucsi_run_command with ucsi_send_command
in the helpers used during port registration also fixes a number of
code paths after registration which call ucsi_run_command() without
holding the ppm_lock:
1. ucsi_altmode_update_active() call in ucsi/displayport.c
2. ucsi_register_altmodes() call from ucsi_handle_connector_change()
   (through ucsi_partner_change())

John reported screaming irq caused by rt1711h when system boot[1],
this is because irq request is done before tcpci_register_port(),
so the chip-&gt;tcpci has not been setup, irq handler is entered but
can't do anything, this patch is to address this by moving the irq
request after tcpci_register_port().

The PMC needs to be notified separately about HPD (hotplug
detected) signal being high after mode entry. There is a bit
"HPD High" in the Alternate Mode Request that the driver
already sets, but that bit is only valid when the
DisplayPort Alternate Mode is directly entered from
disconnected state.

<title>usb: typec: Ensure USB_ROLE_SWITCH is set as a dependency for tps6598x</title>

<id>e9ccc35b86653cb15e9bffbe2cbef8781ea2c1dd</id>
<content type='text'>
When I switched on USB role switching for the tps6598x I completely forgot
to add the Kconfig dependency.

Ensure USB_ROLE_SWITCH is selected to prevent the typs6598x driver being
compiled in but the role-switch driver being compiled as a module, leading
to link error.
