This patch set adds support for automatic configuration of GSBI DMA CRCI values. DMA operations require that the ADM CRCI mux values be properly configured in the TCSR (Top Control and Status Register) block. During probing of a GSBI device, the client mode must be declared and this can be used to lookup the correct TCSR ADM CRCI MUX settings and then program them so that they are correct before any clients are populated. These patches add the TCSR as a syscon device and that allows the GSBI to access and manipulate the ADM CRCI MUX registers to correctly configure the values based on the GSBI port configuration.
