"make dtbs_check" says:
bias-disable: boolean property with value b'\x00\x00\x00\x00'
Fix this by dropping the offending value.
Fixes: be497abe19bf08fb ("arm64: dts: qcom: Add support for Xiaomi Mi Mix2s")

Marked RFC as I do not have the hardware or documentation.
Perhaps the "bias-disable" property should be dropped instead?

This is correct, the ` = <0>` is a downstream style, but it does actually mean to disable the bias
afaik, from downstream docs:
- bias-disable:
Usage: optional
Value type: <none>
Definition: The specified pins should be configued as no pull.
