[PATCH v2 0/8] arm64: mediatek: mt8186-corsola: Consolidate and add new devices

[Chen-Yu Tsai]

Hi everyone,

This is v2 of my "component probe for Corsola devices" series.

Changes since v1:
- Reworded commit message for Elan I2C-HID binding change
- Dropped I2C address constraint from Elan I2C-HID binding completely
- Dropped enum from new compatible string entry in Elan I2C-HID binding
- Picked up Rob's ack on two binding changes
- Rebased onto next-20250417, resolving conflicts with "spherion
  component prober" changes
- Link to v1:
  https://lore.kernel.org/all/20250312104344.3084425-1-wenst@chromium.org/

Here's a follow up series of the I2C component probers for Chromebooks.
This series enables the component prober for the Corsola series of
devices, combines the two existing Voltorb SKUs, and adds a new
device, codename Squirtle.

Patch 1 adds a new HID-over-I2C touchscreen from Elan.

Patch 2 merges the Voltorb entries in the device tree bindings into one.

Patch 3 adds a new entry for the Squirtle device to the bindings.

Patch 4 fixes up the existing device trees for the component prober to
be active.

Patch 5 merges the device trees for the Voltorb device.

Patch 6 adds a device tree file for the Squirtle device, with I2C
components ready to be probed by the prober.

Patch 7 enables the prober to probe trackpads on some devices in the
Corsola family.

Patch 8 enables the prober to probe touchscreens on Squirtle.

Please take a look.


Thanks
ChenYu
