Hi Toshihiro San,

I'm trying to make PM suspend/resume capability for Audio driver when 
audio transmitting is active. I'm using 1710H3 and 2.6.10 kernel.
I make audio_dma_stop() & omap_mcbsp_stop() during suspend and 
audio_start_dma_chain() & omap_mcbsp_start() when resume,
the audio file continue playing normally _but_ LCD begins flickering and 
I see varying of frequency on the LCD from 5MHz to 20kHz.

Could you assist me what else should I do to go into suspend when audio 
is active to avoid LCD flickering issue?

TIA,
Vladimir
