The patch ASoC: simple-card-utils: fixup asoc_simple_card_get_dai_id() ID method has been applied to the asoc tree at https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted. You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail.

It will get DAI ID from OF graph "port", but, we want to consider about "endpoint", too. And, we also want to keep compatibility. This patch fixup it as if (driver has specified DAI ID) use it as DAI ID else if (OF graph endpoint has reg) use it as DAI ID else if (OF graph port has reg) use it as DAI ID else use endpoint count as DAI ID Fixes: commit b6f3fc005a2c8 ("ASoC: simple-card-utils: fixup asoc_simple_card_get_dai_id() counting") Reported-by: Tony Lindgren <tony@xxxxxxxxxxx> Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@xxxxxxxxxxx> Tested-by: Tony Lindgren <tony@xxxxxxxxxxx> Signed-off-by: Mark Brown <broonie@xxxxxxxxxx> --- sound/soc/generic/simple-card-utils.c | 32 +++++++++++++++++++++++---- 1 file changed, 28 insertions(+), 4 deletions(-) diff --git a/sound/soc/generic/simple-card-utils.c b/sound/soc/generic/simple-card-utils.c index 17d8aee43835..b807a47515eb 100644 --- a/sound/soc/generic/simple-card-utils.c +++ b/sound/soc/generic/simple-card-utils.c @@ -269,22 +269,46 @@ EXPORT_SYMBOL_GPL(asoc_simple_card_parse_dai); static int asoc_simple_card_get_dai_id(struct device_node *ep) { + struct device_node *node; + struct device_node *endpoint; struct of_endpoint info; + int i, id; int ret; + /* use driver specified DAI ID if exist */ ret = snd_soc_get_dai_id(ep); if (ret != -ENOTSUPP) return ret; + /* use endpoint/port reg if exist */ + ret = of_graph_parse_endpoint(ep, &info); + if (ret == 0) { + if (info.id) + return info.id; + if (info.port) + return info.port; + } + + node = of_graph_get_port_parent(ep); + /* * Non HDMI sound case, counting port/endpoint on its DT * is enough.
