Nobody is proposing to start from scratch, don't worry. Right now the plan is as follows: 1) compare samsungs latest (2.6.28 based) 6410 support and the mainline 6410 support and determine missing bits (if any). Submit those missing bits 2) compare driver support for 6410 in samsungs 2.6.28 based tree and current mainline. Go over each driver, determine if a) mainline has no driver and samsungs driver will get polished+submitted b) mainline has a different version of the same driver. if there are missing features, submit them on top of what mainline has c) mainline ha a completely different driver. Decide what to do on case-by- case basis. In parallel to 1+2, we want to discuss and refine an actual structure for future SoC's. Once that is done, 3) work on migrating samsungs existing s5p6440, s5pc100, s5pc110 code to conform to the new naming/structure, regularly post this for review 4) eventually submit that code mainline, keeping <= 6410 as-is or only with minimal modifications. 5) work on the various existing and new device drivers, gradually submit them to the respective subsystem maintainers. > > > Finally, we should talk with Ben Dooks who is a maintainer of s3c24xx > > series, so hope Ben's reply especially :) > > You probably want to CC him on messages like this - I've added him here. I've already sent him a mail about a week ago about what's happening at Samsung at the moment, so he should be generally aware. But yes, explicit Cc is still not a bad idea. -- - Harald Welte http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."
