Thank you for your contribution! Sashiko AI review found 1 potential issue(s) to consider:
- [Medium] Two separate GPIO switches map to the same absolute switch code (`SW_DOCK`) in the same `gpio-keys` device, causing erratic state clobbering.

ARM: tegra: Add device-tree for Motorola Atrix 4G and Droid X2
This commit adds device-trees for the Motorola Atrix 4G and Droid X2,
which are NVIDIA Tegra20-based smartphones.

[Severity: Medium]
Both switch-dock-hall-sensor-north and switch-dock-hall-sensor-south map
to the same SW_DOCK code within a single gpio-keys device.
Since the gpio-keys driver creates a single input device for the extcon-keys
node and iterates sequentially over all defined buttons to report their
current state at boot and resume, won't the south sensor state overwrite
the north sensor state before input_sync() is called?
If the device is docked in a way that activates the north sensor but not
the south sensor, it seems this could result in an incorrect undocked state
being reported. At runtime, could changes in one sensor also incorrectly
clobber the shared SW_DOCK state, such as an undocked event being emitted
if the south sensor drops while the north sensor remains active?
