phy: rockchip-inno-usb3: workaround for USB3 PHY disconnection det issue

it loses the ability to detect an absence of a far-end
receiver termination specified in USB3 spec Table 6-21,
and this causes the linkstate to change between SS.Inactive
and Polling state, but not return to correct state Rx.detect.

To workaround this bug, we depends on the hub_event to
detect the port linkstate change and do soft disconnect.
And then do USB3 PHY reset and reinit HCD to recovery
the whole USB3.

The workaround process is:
Plug out USB3 device -> hub_event detect PLC and find
USB 3.0 port in the Inactive -> call usb_remove_device()
to do soft disconnect -> call usb_phy_notify_connect()
-> send notifier to DWC3 controller driver to do USB3

UPSTREAM: PM / Domains: Allow runtime PM during system PM phases

In cases when a PM domain isn't powered off when genpd's ->prepare()
callback is invoked, genpd runtime resumes and disables runtime PM for the
device. This behaviour was needed when genpd managed intermediate states
during the power off sequence, as to maintain proper low power states of
devices during system PM suspend/resume.

Commit ba2bbfbf6307 (PM / Domains: Remove intermediate states from the
power off sequence), enables genpd to improve its behaviour in that
respect.

The PM core disables runtime PM at __device_suspend_late() before it calls
a system PM "late" callback for a device. When resuming a device, after a
corresponding "early" callback has been invoked, the PM core re-enables
runtime PM.

By changing genpd to allow runtime PM according to the same system PM
phases as the PM core, devices can be runtime resumed by their
corresponding subsystem/driver when really needed.

In this way, genpd no longer need to runtime resume the device from its
->prepare() callback. In most cases that avoids unnecessary and energy-
wasting operations of runtime resuming devices that have nothing to do,
only to runtime suspend them shortly after.

Although, because of changing this behaviour in genpd and due to that
genpd powers on the PM domain unconditionally in the system PM resume
"noirq" phase, it could potentially cause a PM domain to stay powered
on even if it's unused after the system has resumed. To avoid this,
schedule a power off work when genpd's system PM ->complete() callback
has been invoked for the last device in the PM domain.

To clean up the code, drop these wrapper functions as they have

to the pm_generic_*() helper functions.

While changing this, it has bocame clear that some of the current

UPSTREAM: PM / Domains: Allow genpd to power on during system PM phases

If a PM domain is powered off when the first device starts its system PM
prepare phase, genpd prevents any further attempts to power on the PM
domain during the following system PM phases. Not until the system PM
complete phase is finalized for all devices in the PM domain, genpd again
allows it to be powered on.

This behaviour needs to be changed, as a subsystem/driver for a device in
the same PM domain may still need to be able to serve requests in some of
the system PM phases. Accordingly, it may need to runtime resume its
device and thus also request the corresponding PM domain to be powered on.

To deal with these scenarios, let's make the device operational in the
system PM prepare phase by runtime resuming it, no matter if the PM domain
is powered on or off. Changing this also enables us to remove genpd's
suspend_power_off flag, as it's being used to track this condition.
Additionally, we must allow the PM domain to be powered on via runtime PM
during the system PM phases.

This change also requires a fix in the AMD ACP (Audio CoProcessor) drm
driver. It registers a genpd to model the ACP as a PM domain, but
unfortunately it's also abuses genpd's "internal" suspend_power_off flag
to deal with a corner case at system PM resume.

More precisely, the so called SMU block powers on the ACP at system PM
resume, unconditionally if it's being used or not. This may lead to that
genpd's internal status of the power state, may not correctly reflect the
power state of the HW after a system PM resume.

Because of changing the behaviour of genpd, by runtime resuming devices in
the prepare phase, the AMD ACP drm driver no longer have to deal with this
corner case. So let's just drop the related code in this driver.

UPSTREAM: PM / Domains: Remove redundant pm_runtime_get|put*() in pm_genpd_prepare()

The PM core increases and decreases the runtime PM usage count in the
system PM prepare phase. This makes some of the pm_runtime_get|put*()
calls in pm_genpd_prepare() redundant, so let's remove them.

5 years agoFROMLIST: serial: 8250_dw: Avoid "too much work" from bogus rx timeout interrupt
Douglas Anderson [Mon, 6 Feb 2017 23:30:00 +0000 (15:30 -0800)]
FROMLIST: serial: 8250_dw: Avoid "too much work" from bogus rx timeout interrupt

On a Rockchip rk3399-based board during suspend/resume testing, we
found that we could get the console UART into a state where it would
print this to the console a lot:
  serial8250: too much work for irq42

Followed eventually by:
  NMI watchdog: BUG: soft lockup - CPU#0 stuck for 11s!

Upon debugging I found that we're in this state:
  iir = 0x000000cc
  lsr = 0x00000060

It appears that somehow we have a RX Timeout interrupt but there is no
actual data present to receive.  When we're in this state the UART
driver claims that it handled the interrupt but it actually doesn't
really do anything.  This means that we keep getting the interrupt
over and over again.

Normally we don't actually need to do anything special to handle a RX
Timeout interrupt.  We'll notice that there is some data ready and
we'll read it, which will end up clearing the RX Timeout.  In this
case we have a problem specifically because we got the RX TImeout
without any data.  Reading a bogus byte is confirmed to get us out of
this state.

It's unclear how exactly the UART got into this state, but it is known
that the UART lines are essentially undriven and unpowered during
suspend, so possibly during resume some garbage / half transmitted
bits are seen on the line and put the UART into this state.

The UART on the rk3399 is a DesignWare based 8250 UART.  From mailing
list posts, it appears that other people have run into similar
problems with DesignWare based IP.  Presumably this problem is unique
to that IP, so I have placed the workaround there to avoid possibly of
accidentally triggering bad behavior on other IP.  Also note the RX
Timeout behaves very differently in the DMA case, for for now the
workaround is only applied to the non-DMA case.
