So if you have the luxury of being able to influence (file bugs against or write)

Note: there is an expectation that the _PRP feature to go into the next version

ACPI platform) between the different platform enumeration API's (DT and ACPI).

Oh I wasn't aware. This makes things better, and gives con_id a clear usecase
in the ACPI probe path as well.

If there were ever an (upstream?) ACPI "binding"(?) for the Tegra SDHCI
controller, I would hope it would use the exact same names for the GPIO
signals.

me to!

Amen to that.
