Hi Jessica,

I will be submitting a v3 shortly, the change to the sleep time was not 
necessary for the new panel
to work.

I have been able to re-use the gip sequence from the kd50t048a panel 
used in the Hardkernel Odroid
Go Super as I have been led to believe it is the same elida panel, 
unfortunately the same modes
used by that device do not work for the Odroid Go Ultra and so its still 
necessary to have the
patchset,

Best regards,

Adam
