[PATCH 2/2] arm64: mediatek: mt8195-cherry: Introduce the MT8195 Dojo Chromebook
From: AngeloGioacchino Del Regno
Date: Thu Mar 14 2024 - 06:36:35 EST
Add a devicetree for the Cherry Dojo (HP Chromebook x360 13b-ca0002sa)
convertible type machine.
Differences with the already supported Tomato machines include:
- Different speaker amplifiers (Dual MAX98380, one per channel)
- I2C Touchscreen is on a different address (though still a HID device)
- Has NVMe storage on the PCIe0 controller
- Slightly different keyboard top row keymap
