Subject: [PATCH 0/5] arm64: dts: qcom: fix USB wakeup interrupts again

The USB DP/DM HS PHY interrupts need to be provided by the PDC interrupt
controller in order to be able to wake the system up from low-power
states and to be able to detect disconnect events, which requires
triggering on falling edges.

A recent commit updated the trigger type but failed to change the
interrupt provider as required. This leads to the current Linux driver
failing to probe instead of printing an error during suspend and USB
wakeup not working as intended.

While at it, fix also the SS PHY interrupt so that it too can be used to
wakeup the system up.

Thanks to Konrad for reporting the probe failure on sc8180x and
providing the corresponding PDC interrupts and to Krishna for providing
the remaining PDC interrupts. The exception is for the second controller
on sm8150 whose PDC vectors I inferred from sdm845.

Note sdm670 and sm6375 need similar fixes and I believe Bjorn is trying
to dig out the corresponding vectors. The SS PHY interrupt on sc8180x
should also be fixed.

Also note that these patches have only been compile tested.

Johan
