[PATCH v4 0/8] arm64: dts: librem5-devkit: description updates

[Martin Kepplinger]

Shawn, I included Fabio's feedback despite you've taken the changes already.
I don't know how "far out there" they are already, but in case you want to
rebase / force-push this again, here is v4: It basically only adds one Fixes
tag.


These are additions to the imx8mq-librem5-devkit devicetree description
we are running for quite some time. All users should have them:

revision history
----------------
v4: review by Fabio: add Fixes tag and reorder a bit. thanks.
v3: review by Shawn: newline / hyphen issues; squashed related ones.
    thanks a lot.
    https://lore.kernel.org/linux-arm-kernel/20200224062917.4895-1-martin.kepplinger@puri.sm/
v2: review by Shawn and Guido: remove a battery description
    add SoB tags, coding style fixes, squash and reorder audio
    descritions, remove redundant and unneeded changes.

[PATCH v4 8/8] arm64: dts: librem5-devkit: add lsm9ds1 mount matrix

[Martin Kepplinger]

The IMU chip on the librem5-devkit is not mounted at the "natural" place
that would match normal phone orientation (see the documentation for the
details about what that is).

Since the lsm9ds1 driver supports providing a mount matrix, we can describe
the orientation on the board in the dts:

Create a right-handed coordinate system (x * -1; see the datasheet for the
axis) and rotate 180 degrees around the y axis because the device sits on
the back side from the display.
