The GPIO ops can be selected by platform_data which allows the
codec platform device to probe without the sound card's driver
intervention.
The downside is that it will request GPIOs on behalf of the codec
device and thus allow only one user on the bus, but it desn't seem
to be a limitation with current code and usage of the GPIO ops is
optional anyway.
The proper approach would presumably be to create a proper Linux
bus driver for L3, should this rather ancient bus specification
suddenly gain more interest.

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().

Currently, if the driver has control of MCLK then it remains
enabled as long as the codec is in STANDBY or above. The MCLK is
only really required in STANDBY when a 3-pole jack is inserted
and the HP detect procedure is required to run.
This patch updates the code to enable/disable the MCLK when moving
between the STANDBY and PREPARE bias level, and when a 3-pole jack
is inserted and HP detection is required, thus saving power at all
other times.

Currently the handling of the PLL in the driver is a little clunky,
and not ideal for all modes. This patch updates the code to make it
cleaner and more sensible for the various PLL states.
Key items of note are:
- MCLK squaring is now handled directly as part of the sysclk()
function, removing the need for a private flag to set this feature.
- All PLL modes are defined as an enum, and are handled as a case
statement in pll() function to clean up configuration. This also
removes any need for a private flag for SRM.
- For 32KHz mode, checks are made on codec master mode and correct
MCLK rates, to avoid incorrect usage of PLL for this operation.
- For 32KHz mode, SRM flag now correctly enabled and fout set to
sensible value to achieve appropriate PLL dividers.

In chromium, the following steps will make codec function fail.
\1. plug in headphones, Play music
\2. run "powerd_dbus_suspend"
\3. resume from S3
After resume, the jack detection will restart and make configuration
for the headset. Meanwhile, the playback prepares and starts to work.
The two sequences will conflict and make wrong register configuration.
Originally, the driver adds protection for the case when it finds
the playback is active. But the "powerd_dbus_suspend" command will
close the pcm stream before suspend. Therefore, the driver can't
detect the playback after resume, and the protection not works.
For the issue, the driver raises protection every time after resume.
The protection will release after jack detection and configuration
completes, and then the playback just will goes on.
