Squashed backup commit (no shallow-clone history issues) of xiaomi-mt6833-dev/kernel_xiaomi_mt6833 (lineage-23.2 branch, upstream commit 9eece662e) plus all fixes applied to get everpal_defconfig building clean against a modern (GCC 15.2.0) toolchain -- see the previous commit message on the lineage-23.2 branch (also in this repo history is not available here since this is a squashed snapshot; full incremental history lives in the local DL380 checkout and the upstream GitHub remote).

Description:
|
|
This is mounting matrix for motion sensors. Mounting matrix
|
|
is a 3x3 unitary matrix. A typical mounting matrix would look like
|
|
[0, 1, 0; 1, 0, 0; 0, 0, -1]. Using this information, it would be
|
|
easy to tell the relative positions among sensors as well as their
|
|
positions relative to the board that holds these sensors. Identity matrix
|
|
[1, 0, 0; 0, 1, 0; 0, 0, 1] means sensor chip and device are perfectly
|
|
aligned with each other. All axes are exactly the same.
