Subject: [PATCH v3 0/4] Add Acer Aspire 1

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)
