ENGR00182769 HDMI: No sound when playing audio in 480p mode

2012-05-18T06:59:53+00:00

It is cause by HDMI audio driver can't get right pixel clock
from IPU driver if pixel clock source from HSP clock not from
DI clock.
HDMI driver get pixel clock by call clk_get_rate() function,
but the function return actually clock, in some videomode the
actually pixel clock is not right equal the pixel clock in CEA spec.

Get pixel clock from video mode struct instead of CCM register.
480P HDMI audio can work.

ENGR00179601 Synopsys approved hdmi fifo workaround - rev 3

2012-04-14T01:08:57+00:00

This patch includes some of the clk enable/disable changes from rev2

Check the version of the HDMI IP to determine whether the fifo
threshold needs to be high.  The i.Mx6dl version of the HDMI doesn't
need the workaround.  All other parts of the workaround are used
for both parts for code simplicity.

----------------------------------------------------------
For i.Mxq, set the Threshold of audio fifo as: FIFO depth - 2 (fixed
and independent of the number of channels actually used).

Use unspecified length ahb bursts (using fixed INCRx will make the
audio dma fail).

Additionally and in order to get it working on all conditions it will
be necessary to run the following sw steps at startup of video and audio
(or when video changes or audio changes):

1-Configure AUD_N1 and AUD_CTS1 registers with final value and let the
  AUD_N2, AUD_N3, AUD_CTS2 and AUD_CTS3 to 0s.
2-Configure start and end addresses of audio DMA registers.
3-Start DMA operation
4-Configure the AUD_CTS2 and AUD_CTS3 with the final value.
5-Configure the AUD_N2 and AUD_N3 with final value.
