This improves device-tree of Lenovo Flex/Yoga 5G laptop with these changes:
- fix GPU firmware path (make it use device-specific firmware directory);
- set names for i2c hid nodes (so it is clear which node corresponds to
which device);
- add touchscreen support;
- fix touchpad issue when it gets stuck on right or middle click;
- allow UFS regulators load/mode setting;
- move some pinctrl properties to appropriate nodes.
---
Changes in v2:
- fix the description for touchpad i2c patch;
- move touchscreen reset gpio pinctrl to appropriate node;
- add a patch splitting and moving some other pinctrl stuff, so it is in
correct nodes as well;
- change touchscreen interrupt from edge falling to active low, because
edge falling is apparently against i2c hid specification, and ACPI uses
active low as well.
