From: Rob Clark <robdclark@chromium.org>

This is essentialy a squash of a bunch of history of cheza dt updates
from chromium kernel, some of which were themselves squashes of history
from older chromium kernels.

I don't claim any credit other than wanting to more easily boot upstream
kernel on cheza to have an easier way to test upstream driver work ;-)

I've added below in Cc tags all the original actual authors (apologies
if I missed any).

Updated from review comments and squashed.  I left out the the patch
related to deleting gpu_mem/zap_shader nodes as the corresponding
patch that adds them in sdm845.dtsi hasn't landed yet, but once it
has we will need to revisit that patch for cheza.

+	 * - The only source of DP is the single native Type C port.
+	 * - On cheza we want to be able to hook DP up to _either_ of the
+	 *   two Type C connectors and want to be able to achieve 4 lanes of DP.
+	 * - When you configure a Type C port for 4 lanes of DP you lose USB3.
+	 * - In order to make everything work, the native Type C port is always
+	 *   configured as 4-lanes DP so it's always available.
+	 * - The extra USB3 port on SDM845 goes to a USB 3 hub which is then
+	 *   sent to the two Type C connectors.
+	 * - The extra USB2 lines from the native Type C port are always
+	 *   setup as "peripheral" so that we can mux them over to one connector
+	 *   or the other if someone needs the connector configured as a gadget
+	 *   (but they only get USB2 speeds).
+	 *
+	 * All the hardware muxes would allow us to hook things up in different
+	 * ways to some potential benefit for static configurations (you could
+	 * achieve extra USB2 bandwidth by using two different ports for the
+	 * two conenctors or possibly even get USB3 peripheral mode), but in
