Recent i.MX51 Activities on Mainline Linux

[RobertSchwebel]

Hi,                                                                                                                                    
                                                                                                                                       
This is just a short note that we recently won a secret customer project which brings us into the position to be able to mainline many more MX51 components!
                                                                                                                                       
Watch the ARM Linux Kernel mailing list or Sascha Hauer's maintainer tree to get the latest updates. We have unified the different PMICs, are working on SPI, CAN-via-SPI, have AC97 audio, SDMA plus much more things.
                                                                                                                                       
Interested in the really sexy things, like accelerated video + graphics? Drop us a note! We have nicely reworked VPU drivers for the MX27 which could be ported to MX51 as well, have started reworking the IPUv3 drivers and many more. Things will go into the mainline the faster the more projects we get behind these activities! :-)

Hi,

I want to test AC97 on iMX51.

We need SSI initialization for AC97 codec.

Please let me know where the code is available.

Regards,

Geetha

Thanks for the link; in short, I am working on a fsl-based kernel for a custom video preview pipe (greyscale in -> framerate adaption -> LUT -> vf ), so syncing buffers on NFAcks gives a little bit more slack than the eof interrupt. Will work along your lines.. Simon

Simon, what exactly do you need? Btw, the latest code is inSaschas git tree. Robert

Great stuff - did you implement sdma irq handlers as well? Would be interested in them (or implement my own)
