18 * Most DCRs used for controlling devices such as the MAL, DMA engine,
19 * etc... are obtained for the device tree.
21 * The definitions in this files are fixed DCRs and indirect DCRs that
22 * are commonly used outside of specific drivers or refer to core
23 * common registers that may occasionally have to be tweaked outside
24 * of the driver main register set
