The patch set contains clk related register settings, see mxs_set_lcdclk, in patch [PATCH V2 07/14] imx: mx6: add clock api for lcdif. I need to address your comments about this patch. The is_cpu_type(MXC_CPU_MX6SX) handles the LCDIF2. I have not tested it for lCDIF2, but it's in fsl's vendor uboot, it should work. For now, I only have 6ul and 7d in hand to test LCDIF1.
