Re: [PATCH v2 2/2] ARM: dts: imx51: Fix inconsistent display port names

Hi Marco,

The parallel display interface pad groups are called DISP0 and DISP1 in 
the reference manuals, but in the i.MX51 dts files they are called DISP1 
and DISP2.
To me, this sounds like they are called DISP0/1 also in the i.MX51
reference manual, but if I'm not mistaken, the i.MX51 reference manual
actually calls them DISP1/2.
I'd change the comment to say something to the effect of: "Contrary to
later SoCs, the parallel display interface pad groups on i.MX51 are
called DISP1 and DISP2, not DISP0 and DISP1."
Fix this inconsistence by changing the DISP names in the i.mx51 dts.
