+ *      (3) the peripheral's bus & kernel clock at the PRCC level
+ *
+ * (1) and (2) are handled by defining clk structs (DEFINE_PRCMU_CLK) for each
+ * of the cluster and peripheral clocks, and hooking these as the parents of
+ * the individual peripheral clocks.
+ *
+ * (3) is handled by specifying the bits in the PRCC control registers required
+ * to enable these clocks and modifying them in the ->enable and
+ * ->disable callbacks of the peripheral clocks (DEFINE_PRCC_CLK).
+ *
+ * This structure describes both the PRCMU-level clocks and PRCC-level clocks.
+ * The prcmu_* fields are only used for the PRCMU clocks, and the cluster,
+ * prcc, and parent pointers are only used for the PRCC-level clocks.

+          Historically, the kernel has used strongly ordered mappings to
+          provide DMA coherent memory.  With the advent of ARMv7, mapping
+          memory with differing types results in unpredictable behaviour,
+          so on these CPUs, this option is forced on.
+
+          Multiple mappings with differing attributes is also unpredictable
+          on ARMv6 CPUs, but since they do not have aggressive speculative
+          prefetch, no harm appears to occur.
+
+          However, drivers may be missing the necessary barriers for ARMv6,
+          and therefore turning this on may result in unpredictable driver
+          behaviour.  Therefore, we offer this as an option.
+
+          You are recommended say 'Y' here and debug any affected drivers.
