+ * Function: omxVCM4P10_InvTransformDequant_ChromaDC (6.3.5.6.4)
+ *
+ * Description:
+ * This function performs inverse 2x2 Hadamard transform and then dequantizes
+ * the coefficients.
+ *
+ * Input Arguments:
+ *
+ * pSrc - Pointer to the 2x2 array of the 2x2 Hadamard-transformed and
+ * quantized coefficients. 8 byte alignment required.
+ * iQP - Quantization parameter; must be in the range [0,51].
+ *
+ * Output Arguments:
+ *
+ * pDst - Pointer to inverse-transformed and dequantized coefficients.
+ * 8-byte alignment required.
+ *
+ * Return Value:
+ *
+ * OMX_Sts_NoErr - no error
+ * OMX_Sts_BadArgErr - bad arguments; returned if any of the following
+ * conditions are true:
+ * - at least one of the following pointers is NULL: pSrc
+ * - pSrc or pDst is not aligned on an 8-byte boundary
