+title: Linksys Northstar partitioning
+
+description: |
+  Linksys devices based on Broadcom Northstar architecture often use two
+  firmware partitions. One is used for regular booting, the other is treated as
+  fallback.
+
+  This binding allows defining all fixed partitions and marking those containing
+  firmware. System can use that information e.g. for booting or flashing
+  purposes.

+title: Nvmem cells
+
+description: |
+  Any partition containing the compatible "nvmem-cells" will register as a
+  nvmem provider.
+  Each direct subnodes represents a nvmem cell following the nvmem binding.
+  Nvmem binding to declare nvmem-cells can be found in:
+  Documentation/devicetree/bindings/nvmem/nvmem.yaml
