[ Upstream commit 6bb1e09c4c ]
Cabling used to connect devices to USBH1 on RDU2 does not meet USB
spec cable quality and cable length requirements to operate at High
Speed, so limit the port to Full Speed only.

The correct DT property for specifying a GPIO used for reset
is "reset-gpios", the driver now accepts this name, use it here.
Note the GPIO polarity in the driver was ignored before and always
assumed to be active low, when all the DTs are fixed we will start
respecting the specified polarity. Switch polarity in DT to the
currently assumed one, this way when the driver changes the
behavior will not change.

- i.MX6SSL from NXP
- Renesas RZ/N1D SoC (R9A06G032), Dual Cortex-A7 with Ethernet, CAN and

- TI AM654 SoC, Quad Cortex-A53, safety subsystem with Cortex-R5

New boards and systems:

- Marvell Armada388-based Helios4 board from SolidRun
- Samsung Aires-based phones (s5pv210)
- Allwinner A64-based Pinebook laptop

of boards/platforms.

The Marvell switches report their interrupts in a level sensitive way.
When using edge sensitive detection a race condition in the interrupt
handler of the swich might result in the OS to miss all future events
which might make the switch non-functional.
The problem is that both mv88e6xxx_g2_irq_thread_fn() and
mv88e6xxx_g1_irq_thread_work() sample the irq cause register
(MV88E6XXX_G2_INT_SRC and MV88E6XXX_G1_STS respectively) once and then
handle the observed sources. If after sampling but before all observed
irq sources are handled a new irq source gets active this is not noticed
by the handler which returns unsuspecting, but the interrupt line stays
active which prevents the edge detector to kick in.
All device trees but imx6qdl-zii-rdu2 get this right (most of them by
not specifying an interrupt parent). So fix imx6qdl-zii-rdu2
accordingly.
