Your syscon.yaml change is not valid if you have child nodes. Do a
specific binding for this block.

Do you mean in addition to having platform specific binding for
scm-conf, I need to have platform specific binding for serdes-ln-ctrl.
Since the driver doesn't do any platform specific stuff, the driver
doesn't have to change. Is that correct?

I mean 'dt-bindings: syscon: Add TI's J721E specific compatible string'.
While not currently enforced because 'unevaluatedProperties: false'
doesn't yet do anything, the intent with syscon.yaml is child nodes
are not allowed. If you have child nodes, you need your own schema.

The USB controllers can be connected to one of the 2 SERDESes
using a MUX. Add a MUX controller node fot that.

USB0 supports super-speed mode on the EVM. Enable that.
On the EVM, USB0 uses SERDES3 for super-speed lane.
Since USB0 is a type-C port, it needs to support lane swapping
for cable flip support. This is provided using SERDES lane
swap feature. Provide the Type-C cable orientation GPIO
to the SERDES Wrapper driver.

The Type-C compainon chip on the board needs ~133ms (tCCB_DEFAULT)
to debounce the CC lines in order to detect attach and plug orientation
and reflect the correct DIR status. [1]
On the EVM however we need to wait upto 700ms before sampling the
Type-C DIR line else we can get incorrect direction state.
