[PATCH 2/2] pinctrl: tegra238: add missing AON pin groups

[Prathamesh Shete]

Add 24 pin groups on ports EE, FF, GG and HH to the AON pin controller
group table (tegra238_aon_groups[]). Their pin arrays, drive-group
macros and pin descriptors were already defined, but the matching
PINGROUP() entries were not present, so these pins could not be muxed
or configured through the AON pin controller.

The pin arrays were not referenced, so the build emitted
-Wunused-const-variable warnings, and commit 119de2c33d96 ("pinctrl:
tegra238: remove unused entries") removed three of them. Restore those
arrays and add the full set of PINGROUP() entries to make the pins
usable.

dt-bindings: pinctrl: tegra238: add missing AON pin groups

Add 24 pin groups, and their matching drive groups, on ports EE, FF,
GG and HH to the Tegra238 AON pinmux binding. These groups are present
on the AON pin controller, so device trees that mux these pins through
it validate against the schema.

[Severity: Low]
Does this order violate the comment preceding the drive groups?

The comment explicitly specifies that the drive groups should be ordered by
port (PAA, PBB, PCC, PDD, PEE, PFF, PGG, PHH).

However, the newly added drive groups appear to be jumbled and not ordered
by port. For example, drive_soc_gpio86_phh3 appears before
drive_soc_gpio72_pff3, and drive_soc_gpio76_pff7 appears before
drive_soc_gpio74_pff5.

Should these be sorted sequentially by port to match the documented
formatting constraint?
