The laptop design is similar to trogdor in the choice of primary components but the specifics on usage of those differ slightly. Add the devicetree for the laptop with support for most of the hardware present. Signed-off-by: Nikita Travkin --- 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. Changed in v2: - Various styling, ordering and node naming issues fixed.
