i.MX6ULL has different speed grades than i.MX6UL. Signed-off-by: Sébastien Szymanski <sebastien.szyman...@armadeus.com> --- Notice that the i.MX6ULL RM says: 2b'00: 800MHz; 2b'01: 850MHz; 2b'10: 1GHz; 2b'11: 1.2Ghz; which seems incorrect. The commit [1] confirmed it, but I cannot find any 996MHz i.MX6ULL on the NXP website. According to [2], there are only 3 i.MX6ULL versions: 528, 792 and 900MHz.
