Hi,
I'm going to adapt Freescale's i.MX27 CPU to the SoC sound support via I2S. I found the imx21 already in the repository (may it will help for my job). Is anybody else working on i.MX27 support (to avoid to reinvention everything)?
It's not fully supported atm. However I've had interest from a few folks who are interested in completing support.
Currently working :-
o i.MX2x SSI is complete (same as i.MX3)
But why there are different files for different CPUs when their hardware "on chip" is the same?
Todo:
o i.MX2x DMA is not completed. There is a half ASoC ported OSS based implementation in git atm, although it's not complete due to my only remaining i.MX21 board dying. Should be only about 1 weeks effort to complete this.
I have an i.MX27 and i.MX31 board here. Question is, what kind of CPU/architecture support you are using for i.MX21? The one from arch/arm/imx? Or something from arch/arm/mxc3, arch/arm/plat-mxc?
So now we have a few (nearly working) implementations. What should be used? The implementations from soc/imx or from soc/fsl?
