Hi All,

So I recently bought a (second-hand) Bay Trail tablet which has its LCD
mounted upside-down. As such I've ported Ville Syrjala's patches to deal
with this to current mainline and I'm hereby posting them upstream
for merging.

These patches fix the kernel-console as well as the boot-splash
(at leats plymouth does not reset the rotation) being upside down as
soon as a native kms driver such as the i915 driver is loaded.

This fixes the orientation of the displayed image from boot till the
Xserver or a Wayland compositor takes over.

I've a patch for iio-sensor-proxy which fixes the rotation under Xorg /
Wayland when using a desktop environment which honors iio-sensor-proxy's
rotation detection:

Regards,

Hans
