 * All these mipi controller register declaration provide reg address offset,
 * bits width, bit offset for a specified register bits. With these message, we
 * can set or clear every bits individually for a 32bit widthregister. We use
 * DSI_HOST_BITS macro definition to combinat these message using the following
 * format: val(32bit) = addr(16bit) | width(8bit) | offest(8bit)
 * For example:
 *    #define SHUTDOWNZ           DSI_HOST_BITS(0x004, 1, 0)
 * means SHUTDOWNZ is a signal reg bit with bit offset qual 0,and it's reg addr
 * offset is 0x004.The conbinat result  = (0x004 << 16) | (1 << 8) | 0
