LinuxLists.cc - [PATCH 00/11] ARM/arm64: dts: qcom: fix USB wakeup interrupt types

Subject: [PATCH 00/11] ARM/arm64: dts: qcom: fix USB wakeup interrupt types

When testing a recent series that addresses resource leaks in the
Qualcomm dwc3 glue driver [1], I realised that probe deferral can break
wakeup from suspend due to how the wakeup interrupts are currently
requested.

The following series fixes this by no longer overriding the firmware
defined trigger types for the wakeup interrupts:

https://lore.kernel.org/lkml/[email protected]/

It turns out a number Qualcomm devicetrees have also gotten the trigger
types wrong, something which this series addresses.

Specifically, the HS/SS PHY wakeup interrupts are level triggered while
the DP/DM HS PHY interrupts are edge triggered, and which edge to
trigger on depends both on the use-case and on whether a Low speed or
Full/High speed device is connected.

Fortunately, there should be no dependency between this series and USB
one as all devicetree use the correct trigger type for the HS/SS PHY
interrupts and the HS one has never been armed by Linux anyway. The
DP/DM interrupt trigger types are also updated on suspend currently.

The only exception may be sc7280 where a recent cleanup patch
inadvertently switched the SS and DP trigger types, but that one should
just be backported anyway.

Note that the binding example is updated in the USB driver series
mentioned above.

Subject: [PATCH 02/11] arm64: dts: qcom: sa8775p: fix USB wakeup interrupt types

The DP/DM wakeup interrupts are edge triggered and which edge to trigger
on depends on use-case and whether a Low speed or Full/High speed device
is connected.

Note that only triggering on rising edges can be used to detect resume
events but not disconnect events.

Konrad reported off-list that the sc8180x patch in this series breaks
probe of the dwc3 driver.

Turns out a number of these SoCs were using GIC interrupts for the
DP/DM_HS_PHY interrupts despite the fact that the driver tries to
reconfigure these as IRQ_TYPE_EDGE_FALLING (which the GIC does not
support) to detect disconnect events during suspend.

This is obviously broken and the proper fix is to replace the GIC
interrupts with the corresponding PDC interrupts. I believe Konrad is
digging out the magic numbers at this moment.

The following patches will need a follow-up fix:

SM6375, I think GIC_SPI is fine but I will try to get back on this.

Thanks, Krisha, that helps a lot.

I've sent two series (for arm and arm64) based on yours and Konrad's

Do you have the corresponding numbers also for the second controller on
SM8150? I inferred them from SDM845, but it would good to verify that.

And can someone dig out the corresponding SS PHY interrupt for sc8180x?
