+Renesas R-Car LVDS Encoder
+==========================
+
+These DT bindings describe the LVDS encoder embedded in the Renesas R-Car
+Gen2, R-Car Gen3 and RZ/G SoCs.
+
+Required properties:
+
+- compatible : Shall contain one of
+  - "renesas,r8a7743-lvds" for R8A7743 (RZ/G1M) compatible LVDS encoders
+  - "renesas,r8a7790-lvds" for R8A7790 (R-Car H2) compatible LVDS encoders
+  - "renesas,r8a7791-lvds" for R8A7791 (R-Car M2-W) compatible LVDS encoders
+  - "renesas,r8a7793-lvds" for R8A7793 (R-Car M2-N) compatible LVDS encoders
+  - "renesas,r8a7795-lvds" for R8A7795 (R-Car H3) compatible LVDS encoders
+  - "renesas,r8a7796-lvds" for R8A7796 (R-Car M3-W) compatible LVDS encoders
+  - "renesas,r8a77970-lvds" for R8A77970 (R-Car V3M) compatible LVDS encoders
+  - "renesas,r8a77995-lvds" for R8A77995 (R-Car D3) compatible LVDS encoders
+
+- reg: Base address and length for the memory-mapped registers
+- clocks: A phandle + clock-specifier pair for the functional clock
+- resets: A phandle + reset specifier for the module reset
+
+Required nodes:
+
+The LVDS encoder has two video ports. Their connections are modelled using the
+OF graph bindings specified in Documentation/devicetree/bindings/graph.txt.
+
+- Video port 0 corresponds to the parallel RGB input
+- Video port 1 corresponds to the LVDS output
+
+Each port shall have a single endpoint.
+
+
+Example:
+
+	lvds0: lvds@feb90000 {
+		compatible = "renesas,r8a7790-lvds";
+		reg = <0 0xfeb90000 0 0x1c>;
+		clocks = <&cpg CPG_MOD 726>;
+		resets = <&cpg 726>;
+
+		ports {
+			#address-cells = <1>;
+			#size-cells = <0>;
+
+			port@0 {
+				reg = <0>;
+				lvds0_in: endpoint {
+					remote-endpoint = <&du_out_lvds0>;
+				};
+			};
+			port@1 {
+				reg = <1>;
+				lvds0_out: endpoint {
+				};
+			};
+		};
+	};

+ * Fence helper functions to deal with KFD memory eviction.
+ * Big Idea - Since KFD submissions are done by user queues, a BO cannot be
+ *  evicted unless all the user queues for that process are evicted.
+ *
+ * All the BOs in a process share an eviction fence. When process X wants
+ * to map VRAM memory but TTM can't find enough space, TTM will attempt to
+ * evict BOs from its LRU list. TTM checks if the BO is valuable to evict
+ * by calling ttm_bo_driver->eviction_valuable().
+ *
+ * ttm_bo_driver->eviction_valuable() - will return false if the BO belongs
+ *  to process X. Otherwise, it will return true to indicate BO can be
+ *  evicted by TTM.
+ *
+ * If ttm_bo_driver->eviction_valuable returns true, then TTM will continue
+ * the evcition process for that BO by calling ttm_bo_evict --> amdgpu_bo_move
+ * --> amdgpu_copy_buffer(). This sets up job in GPU scheduler.
+ *
+ * GPU Scheduler (amd_sched_main) - sets up a cb (fence_add_callback) to
+ *  nofity when the BO is free to move. fence_add_callback --> enable_signaling
+ *  --> amdgpu_amdkfd_fence.enable_signaling
+ *
+ * amdgpu_amdkfd_fence.enable_signaling - Start a work item that will quiesce
+ * user queues and signal fence. The work item will also start another delayed
