What does "for full HDMI audio support" mean? What's the partial support? =) Tomi ``` ## Re: \[PATCH 05/19\] OMAPDSS: Kconfig: Add depencies and help section to OMAP4\_DSS\_HDMI\_AUDIO - From: Jyri Sarha \ - Date: 2014-05-16 11:56:48 - Message: https://ratatoskr.run/linux-fbdev/2014/05/8091128.md ```text On 05/16/2014 01:52 PM, Tomi Valkeinen wrote: > Hi, > > On 12/05/14 12:12, Jyri Sarha wrote: >> Signed-off-by: Jyri Sarha >> --- >> drivers/video/fbdev/omap2/dss/Kconfig | 10 +++++++++- >> 1 file changed, 9 insertions(+), 1 deletion(-) >> >> diff --git a/drivers/video/fbdev/omap2/dss/Kconfig b/drivers/video/fbdev/omap2/dss/Kconfig >> index 8921a7a..ecc2f50 100644 >> --- a/drivers/video/fbdev/omap2/dss/Kconfig >> +++ b/drivers/video/fbdev/omap2/dss/Kconfig >> @@ -70,7 +70,15 @@ config OMAP4_DSS_HDMI >> HDMI support for OMAP4 based SoCs. >> >> config OMAP4_DSS_HDMI_AUDIO >> - bool >> + bool "HDMI audio support for OMAP4" >> + depends on OMAP4_DSS_HDMI >> + depends on SND_OMAP_SOC=y || OMAP2_DSS = SND_OMAP_SOC >> + default y >> + help >> + HDMI audio support for OMAP4 based SoCs.

The ASoC DAI component driver provides just that functionality. A machine, platform, and (in this case a dummy) codec component driver is also needed for a complete ALSA device functionality. Anyway, I look into Mark's suggestion of instantiating all the necessary component drivers from the HDMI driver. Best regards, Jyri ```
