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.
