              i.MX6Q    i.MX6DL
DESIGN_ID     0x13      0x13
REVISION_ID   0x0a      0x1a    <--- the only difference
PRODUCT_ID0   0xa0      0xa0
PRODUCT_ID1   0xc1      0xc1
CONFIG0_ID    0x8f      0x8f
CONFIG1_ID    0x01      0x01
CONFIG2_ID    0xf2      0xf2    <--- HDMI 3D TX PHY
CONFIG3_ID    0x02      0x02

I'm not sure, if i.MX6D and MX6S have the same DW HDMI IP as on i.MX6Q
and i.MXDL respectively, and I don't have i.MX6DP or i.MX6QP powered board
on hand to dump the registers.
