/*
* 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).
