+ * The i.MX28 has interesting feature when it comes to register access. There
+ * are four kinds of access to one particular register. Those are:
+ *
+ * 1) Common read/write access. To use this mode, just write to the address of
+ * the register.
+ * 2) Set bits only access. To set bits, write which bits you want to set to the
+ * address of the register + 0x4.
+ * 3) Clear bits only access. To clear bits, write which bits you want to clear
+ * to the address of the register + 0x8.
+ * 4) Toggle bits only access. To toggle bits, write which bits you want to
+ * toggle to the address of the register + 0xc.
+ *
+ * IMPORTANT NOTE: Not all registers support accesses 2-4! Also, not all bits
+ * can be set/cleared by pure write as in access type 1, some need to be
+ * explicitly set/cleared by using access type 2-3.
+ *
+ * The following macros and structures allow the user to either access the
+ * register in all aforementioned modes (by accessing reg_name, reg_name_set,
+ * reg_name_clr, reg_name_tog) or pass the register structure further into
+ * various functions with correct type information (by accessing reg_name_reg).
