[PATCH v3 0/4] Add Acer Aspire 1

From: Nikita Travkin

This series introduces Acer Aspire 1 - A WoA laptop with sc7180.

The dts adds mostly complite support for the hardware and the device,
with minor patches on top, can be used as a normal laptop daily.

Notable features absent from this patch:
- Sound
While the dedicated sound components are defined, since the
ADSP must be used, sound requires additions of that remoteproc
as well some extra "glue" to connect the i2s outputs to it.
I was able to hack together some sound based on sm8250 stuff
but it needs more work.
- Embedded Controller
The laptop has a dedicated EC that controls, notably,
battery/charger and notifies the device about the USB-C DisplayPort
HPD events. As per this patch, there is no battery status
indication and external display support. Also, due to the EC
defaults, the fn key is disabled. I have an experimental driver that
implements all of that, which needs more work and will be submitted
at a later date.
- PSCI OSI Mode
Firmware on this laptop does not support the PC mode, as is usual
for Qualcomm. This change would require adding OSI related
power-domains to the SoC dtsi and is omitted in expectation that
this can be handled when (if?) CrOS team handles their tf-a, like
they did with sc7280.

Changed in v3:
- Disable lpass clocks by default (Konrad)
- Drop status=disabled for mdp in the common soc dtsi (Konrad)
