+title: LiteX SoC Controller driver
+
+description: |
+  This is the SoC Controller driver for the LiteX SoC Builder.
+  Its purpose is to verify LiteX CSR (Control&Status Register) access
+  operations and provide functions for other drivers to read/write CSRs
+  and to check if those accessors are ready to be used.
