ASoC: hdmi-codec: callback function will be called with private data
Current hdmi-codec driver is assuming that it will be registered
from HDMI driver. Because of this assumption, each callback function
has struct device pointer which is parent device (= HDMI).
Then, it can use dev_get_drvdata() to get private data.
OTOH, on some SoC/HDMI case, SoC has VIDEO/SOUND and HDMI IPs.
This case, it needs SoC VIDEO, SoC SOUND and HDMI video, HDMI codec
driver. In DesignWare HDMI IP case, SoC VIDEO (= DRM/KMS) driver tries
to bind DesignWare HDMI video driver, and HDMI codec driver
(= hdmi-codec). This case, above "parent device" of HDMI codec driver
is DRM/KMS driver and its "device" already has private data.
And, from DT and ASoC CPU/Codec/Card binding point of view, HDMI codec
(= hdmi-codec) needs to have "parent device" (= DRM/KMS), otherwise,
it never detect sound card.
Because of these reasons, some driver can't use dev_get_drvdata() to
get private data on hdmi-codec driver. This patch add new void pointer
on hdmi_codec_pdata for private data, and callback function will be
called with it.

ASoC: hdmi-codec: callback function will be called with private data
Current hdmi-codec driver is assuming that it will be registered
from HDMI driver. Because of this assumption, each callback function
has struct device pointer which is parent device (= HDMI).
Then, it can use dev_get_drvdata() to get private data.
OTOH, on some SoC/HDMI case, SoC has VIDEO/SOUND and HDMI IPs.
This case, it needs SoC VIDEO, SoC SOUND and HDMI video, HDMI codec
driver. In DesignWare HDMI IP case, SoC VIDEO (= DRM/KMS) driver tries
to bind DesignWare HDMI video driver, and HDMI codec driver
(= hdmi-codec). This case, above "parent device" of HDMI codec driver
is DRM/KMS driver and its "device" already has private data.
And, from DT and ASoC CPU/Codec/Card binding point of view, HDMI codec
(= hdmi-codec) needs to have "parent device" (= DRM/KMS), otherwise,
it never detect sound card.
Because of these reasons, some driver can't use dev_get_drvdata() to
get private data on hdmi-codec driver. This patch add new void pointer
on hdmi_codec_pdata for private data, and callback function will be
called with it.

ASoC: hdmi-codec: enable multi probe for same device
hdmi-codec driver is common HDMI sound driver,
but it doesn't care about multi sound ports.
For example, hdmi-codec driver is supporting 1 I2S and 1 SPDIF ports,
so, we can't use this driver if HDMI has 2 or more I2S ports.
And we would like to use multi detection.
For example, DesignWare HDMI driver is providing dw_hdmi_bind() to
DRM/KMS driver, and it will setups HDMI video/sound.
Note is that it will be called under for_each loop of ports.
int dw_hdmi_bind(xxx)
{
/* register hdmi-codec driver here */
}
static int xxx_probe(struct platform_device *pdev)
{
for_each_xxx(xx) {
...
dw_hdmi_bind(xxx);
...
}
}
This case, dw_hdmi_bind() would like to use hdmi-codec,
and it will be called multiple times for each ports.
Here, ASoC's CPU/Codec/Card bind will checks each "of_node" on DT,
and hdmi-codec driver is assuming its parent device for it.
But it doesn't care about case.
Thus, ASoC never detect correct sound card in this case.
To solve this issue, this patch checks each parent device,
and names "hdmi-hifi.x" in order to each ports.
And uses struct snd_soc_component_driver :: of_xlate_dai_name
for snd_soc_get_dai_name().

ASoC: hdmi-codec: enable multi probe for same device
hdmi-codec driver is common HDMI sound driver,
but it doesn't care about multi sound ports.
For example, hdmi-codec driver is supporting 1 I2S and 1 SPDIF ports,
so, we can't use this driver if HDMI has 2 or more I2S ports.
And we would like to use multi detection.
For example, DesignWare HDMI driver is providing dw_hdmi_bind() to
DRM/KMS driver, and it will setups HDMI video/sound.
Note is that it will be called under for_each loop of ports.
int dw_hdmi_bind(xxx)
{
/* register hdmi-codec driver here */
}
static int xxx_probe(struct platform_device *pdev)
{
for_each_xxx(xx) {
...
dw_hdmi_bind(xxx);
...
}
}
This case, dw_hdmi_bind() would like to use hdmi-codec,
and it will be called multiple times for each ports.
Here, ASoC's CPU/Codec/Card bind will checks each "of_node" on DT,
and hdmi-codec driver is assuming its parent device for it.
But it doesn't care about case.
Thus, ASoC never detect correct sound card in this case.
To solve this issue, this patch checks each parent device,
and names "hdmi-hifi.x" in order to each ports.
And uses struct snd_soc_component_driver :: of_xlate_dai_name
for snd_soc_get_dai_name().
