The way InvenSense MPU-6050 accelerometer is mounted on the user-facing side of the Pine64 PinePhone mainboard, which makes it rotated 90 degrees counter- clockwise, [1] requires the accelerometer's x- and y-axis to be swapped, and the direction of the accelerometer's y-axis to be inverted.
Rectify this by adding a mount-matrix to the accelerometer definition in the Pine64 PinePhone dtsi file.

Just a brief reminder about this patch... Please, let me know if some further work is needed for it to become accepted.
Notes: See also the linux-sunxi thread [2] that has led to this patch, which provides a rather detailed analysis with additional details and pictures. This patch effectively replaces the patch submitted in that thread.
