ENGR00220181-2 HDMI SDMA: workround for HDMI SDMA audio no sound issue Issue: When playback HDMI audio in SDMA stress test, HDMI audio may stop caused by SDMA channel's failing to work. While checking the SDMA register and HDMI module stauts, we found that SDMA fall to an unknown error state. The issue is detected both in RIGEL TO1.1 and ARIK TO1.2. This patch introduces a workround for this issue: For the memory passed to SDMA core, HDMI driver would allocate it with the attribute of C=0, B=0 instead of C=0, B=1. This patch have be tested in RIGEL TO1.1 for about 60 hours, no issue happens. Signed-off-by: Chen Liangjun <b36089@freescale.com>
