Hi,
Just a gentle reminder, anybody have any comments on this series or
should we start queuing stuff?
Well omap4 seems to work for me just fine, and omap3 in legacy
mode. But looks like omap3 device tree based booting is breaking
after I pulled in your test branch. I get the following on
3630 based dm3730.
Uart4 breaks because of the issue with basic DT blobs. You need at least
this patch:
http://linux-kernel.2935.n7.nabble.com/RFC-PATCH-ARM-OMAP3630-Add-generic-machine-descriptor-td722791.html
... from Nishanth to get it to work right. Otherwise the clock init
tries to use omap3430 clock data for omap3630 which leaves uart4 nodes out.
