Hi Yusuf, > >I want to query status of pwm, resizer and video processing back end >drivers. I ported these drivers from MV tree and using them since >2.6.27.

We are just planning to start working on the vpbe drivers. Initial plan was to port the driver as is using the current architecture. But there are issues that we need to work on to submit the drivers to the community for acceptance. But since you have done initial porting already, could you send us a summary of the changes you have done on these drivers? If you could send us the source code, we could test it as well. >PWM and resizer drivers are relatively simple and in a good shape >for latest kernels. > Is the resizer you are talking about is the DM6446 resizer driver? Is it also based on that on MV kernel? For submission to community, it needs to re-written as a v4l2 device.

We could keep this version in the davinci tree if the changes done are only to support additional devices. Also for submission to open we could use this as base code. >Any comments about the future of these devices are welcome. > >Regards, >Caglar > > >[*] Given that addition of vpfe drivers are real soon plus dsplink > and friends working well with recent kernels, more user space > libraries can be integrated with latest kernels including DMAI > and GStreamer. > >-----BEGIN PGP SIGNATURE----- >Version: GnuPG v2.0.9 (GNU/Linux) >Comment: Using GnuPG with SUSE - http://enigmail.mozdev.org > >iEYEARECAAYFAko2aRYACgkQ/nL+S5dojehMFACfSEaW0apqEjhQGugALct/G/XV >7BIAoLgOafxE2Lp9CBm1UBYOIO+u0qc2 >=O9Sy >-----END PGP SIGNATURE----- > >_______________________________________________ >Davinci-linux-open-source mailing list >[email protected] >http://linux.davincidsp.com/mailman/listinfo/davinci-linux-open-source _______________________________________________ Davinci-linux-open-source mailing list [email protected] http://linux.davincidsp.com/mailman/listinfo/davinci-linux-open-source
