+Subject: [PATCH] overlays: tc358743: Use intra-overlay fragments
+
+The tc358743 overlay was written using a workaround to a problem with
+fragments that target other fragments, but this had the unfortunate
+side-effect of preventing the overlay from being applied at runtime
+(the kernel doesn't allow nodes to be overwritten by an overlay, only
+properties).
+
+The current firmware and dtoverlay/dtparam utilities include support
+for these "intra-overlay" fragments, so remove the workaround and do
+it properly.
