Hi Jessica,

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

Hi Adam,

Got it. If the panel isn't affected by the 20ms sleep time, I'd prefer to keep it since 100ms is a pretty big increase.


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,
Got it. FWIW, I do see the Odroid Go Ultra being described as having the kd50t048a panel [1] [2]. Looking forward to seeing the v3 changes.

Thanks,

Jessica Zhang
