[alsa-devel] [PATCH 0/2] ASoC: rsnd: reborn HDMI sound probing
Hi Mark
I noticed rsnd HDMI sound probing had been broken since v4.15. No board is using it at this point, thus, there is no real issue.
Kuninori Morimoto (2): ASoC: rsnd: add RSND_GEN3 for R-Car Gen3 ASoC: rsnd: don't assume node full path name for HDMI probing

rsnd driver is supporting Gen3. The difference between Gen1 and Gen2 were very big, but, between Gen2 and Gen3 are not so much. Thus, it is assuming Gen2 and Gen3 have compatible, therefore, there is no RSND_GEN3 and rsnd_is_gen3() macro. But in the future, it will need Gen2 and Gen3 different operation, and for Gen4. This patch adds missing RSND_GEN3 and rsnd_is_gen3() macro.

Current ssi.c is assuming below 2 things to probing HDMI node. 1) remote node is including "hdmi0" or "hdmi1" in node name 2) remote_ep->full_name is including full path name
But, these assumptions are broken by below 1) Node names should not use numerical suffixes commit 6b5ac2f1cb11 ("arm64: dts: renesas: r8a7795: Drop bogus HDMI node names suffixes") 2) node full_name no longer include full path name commit a7e4cfb0a7ca ("of/fdt: only store the device node basename in full_name")
Because of these reasons, ssi.c can't probe HDMI on current kernel. This patch probes HDMI0/1 by using its address. Note is that we need to keep updating for this address for future generation chip.

From: Kuninori Morimoto kuninori.morimoto.gx@renesas.com Date: Wed, 11 Apr 2018 02:10:45 +0000 Subject: [PATCH] ASoC: rsnd: don't assume node full path name for HDMI probing
Current ssi.c is assuming below 2 things to probing HDMI node. 1) remote node is including "hdmi0" or "hdmi1" in node name 2) remote_ep->full_name is including full path name
But, these assumptions are broken by below 1) Node names should not use numerical suffixes commit 6b5ac2f1cb11 ("arm64: dts: renesas: r8a7795: Drop bogus HDMI node names suffixes") 2) node full_name no longer include full path name commit a7e4cfb0a7ca ("of/fdt: only store the device node basename in full_name")
Because of these reasons, ssi.c can't probe HDMI on current kernel. This patch probes HDMI0/1 by using its address. Note is that we need to keep updating for this address for future generation chip.

Hi Mark
I got Tested-by privately
For all Tested-by: Nguyen Viet Dung dung.nguyen.aj@renesas.com
I noticed rsnd HDMI sound probing had been broken since v4.15. No board is using it at this point, thus, there is no real issue.
