- * The i.MXS 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).
