From: Francesco Dolcini <francesco.dolcini@xxxxxxxxxxx> Add configuration for parallel data format register, tc358768 supports different mapping on the parallel input RGB interface, enable the configuration for it. Valid values, and the related meaning, are: 0 = R[7:0], G[7:0], B[7:0] 1 = R[1:0], G[1:0], B[1:0], R[7:2], G[7:2], B[7:2] 2 = 8’b0, R[4:0], G[5:0], B[4:0] Use 0 by default, consistently with the HW default.
