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.
