Hi all,
This patch is the follow-up of a request from Philipp to add the Okaya display to the simple panel driver. http://lists.infradead.org/pipermail/linux-arm-kernel/2015-May/346657.html
Regards, Gary

Can you split this change into a separate patch? It needs an Acked-by from one of the device tree binding maintainers, so make sure to Cc them when you repost. scripts/get_maintainer.pl will list them for you.

It strikes me as odd that the porches and VSYNC width should be fixed for the panel. Is this really the case?
