The SBU and HSL orientation may be fixed/static from the mux
PoW. Apparently the retimer may take care of the orientation
of these lines. Handling the static SBU (AUX) and HSL
orientation with device properties.
If the SBU orientation is static, a device property
"sbu-orintation" can be used.

There is actually only one change to the driver in patch 2/4 where I'm

The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:
struct foo {
int stuff;
struct boo array[];
};
