The mechanism is dependent on the common chip core ID and enabled only for a few specific chipsets. But the in-firmware country code/revision is actually a function of the CLM blob, not the chip core. Indeed, while it was reported that the fallback mechanism causes regressions on a board with a chip identified by the driver as BCM4359, we too have such a board with a BCM4359-identified chip, and in our case we really do want to use this fallback mechanism. Put another way, our CLM blob is using ISO3166 country codes, and the revision is always 0. Since this is evidently a property of the firmware, it would be nice to be able to specify this in the device tree, since the driver has no general mechanism for finding out based on the hardware type alone. This series adds such a property: brcm,ccode-map-trivial.
