Hi All,

will ALSA framework provide any customized IOCTL functionality in PCM platform driver.

No.

in my system there is a requirement to get some information from DSP to user space and I am thinking to add IOCTL's, is there any method to accommodate or how we can address this issue?

You can use hwdep device for any extra methods.
