This renames all the pinmux pins, drive groups, and functions so they have a prefix which matches the type name. These lists are also auto- generated using scripts that were also used to generate the kernel pinctrl drivers. This ensures that the lists are consistent between the two. The entries in tegra124_pingroups[] are all updated to remove the columns which are no longer used. All affected code is updated to match. There are differences in the set of drive groups. I have validated this against the TRM. There are differences order of pin definitions in pinmux.c; these previously had significant mismatches with the correct order:-( I adjusted a few entries in pinmux-config-venice2.h since the set of legal functions for some pins was updated to match the TRM.
