When vbus auto discharge is enabled, TCPCI based TCPC transitions
into Attached.SNK/Attached.SRC state. During PR_SWAP, TCPCI based
TCPC would disconnect when partner changes power roles. TCPC has
to be moved APPLY RC state during PR_SWAP. This is done by
ROLE_CONTROL.CC1 != ROLE_CONTROL.CC2 and
POWER_CONTROL.AutodischargeDisconnect is 0. Once the swap sequence
is done, AutoDischargeDisconnect is re-enabled.

On the Realtek high-speed Hub(0bda:5487), the port which has wakeup

There is no need to store the dentry for a fixed filename that we have
the string for. So just have debugfs look it up when we need it to
remove the file, no need to store it anywhere locally.
Note, this driver is broken in that debugfs will not work for more than
one instance of the device it supports. But given that this patch does
not change that, and no one has ever seemed to notice, it must not be an
issue...

Pull timer fixes from Thomas Gleixner:
"Two fixes for timers:
- Use the ALARM feature check in the alarmtimer core code insted of
the old method of checking for the set_alarm() callback.
Drivers can have that callback set but the feature bit cleared. If
such a RTC device is selected then alarms wont work.
- Use a proper define to let the preprocessor check whether Hyper-V
VDSO clocksource should be active.
The code used a constant in an enum with #ifdef, which evaluates to
always false and disabled the clocksource for VDSO"

clocksource/drivers/hyper-v: Re-enable VDSO_CLOCKMODE_HVCLOCK on X86

Merge tag 'x86_urgent_for_v5.13_rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 fixes from Borislav Petkov:
"The three SEV commits are not really urgent material. But we figured
since getting them in now will avoid a huge amount of conflicts
between future SEV changes touching tip, the kvm and probably other
trees, sending them to you now would be best.
The idea is that the tip, kvm etc branches for 5.14 will all base
ontop of -rc2 and thus everything will be peachy. What is more, those
changes are purely mechanical and defines movement so they should be
fine to go now (famous last words).
Summary:
- Enable -Wundef for the compressed kernel build stage
- Reorganize SEV code to streamline and simplify future development"
* tag 'x86_urgent_for_v5.13_rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
x86/boot/compressed: Enable -Wundef
x86/msr: Rename MSR_K8_SYSCFG to MSR_AMD64_SYSCFG
x86/sev: Move GHCB MSR protocol and NAE definitions in a common header
x86/sev-es: Rename sev-es.{ch} to sev.{ch}
- Fix a regression in the conversion of the 64-bit BookE interrupt entry to C.
- Fix KVM hosts running with the hash MMU since the recent KVM gfn changes.
- Fix a deadlock in our paravirt spinlocks when hcall tracing is enabled.
- Several fixes for oopses in our runtime code patching for security mitigations.
- A couple of minor fixes for the recent conversion of 32-bit interrupt entry/exit to C.
- Fix __get_user() causing spurious crashes in sigreturn due to a bad inline asm
constraint, spotted with GCC 11.
- A fix for the way we track IRQ masking state vs NMI interrupts when using the new scv
system call entry path.
- A couple more minor fixes.
