Declare snd_soc_codec_driver structures as const as they are only passed
as an argument to the function snd_soc_register_codec. This argument is
of type const, so declare the structures with this property as const.
In file codecs/sn95031.c, snd_soc_codec_driver structure is also used in
a copy operation along with getting passed to snd_soc_register_codec.
So, it can be made const too.

As a preparatory work to support DP MST this patch adds below changes:
1. Defines the port structure and moves all stream related information
like ELD, converter list, chmap to port.
2. Creates ports for each pin based on the max_ports support.
3. Based on Pin-Port combination creates DAPM Mux widget instead of Pin
to allow user to select a converter.
4. Port zero is the default port when pin does not support MST.

DP MST provides the capability to send multiple video and audio streams
through a single port. This requires the API's between i915 and audio
drivers to distinguish between multiple audio capable displays that can be
connected to a port. Currently only the port identity is shared in the
APIs. This patch adds support for MST with an additional parameter
'int pipe'. The existing parameter 'port' does not change it's meaning.
pipe =
MST : display pipe that the stream originates from
Non-MST : -1
Affected APIs:
struct i915_audio_component_ops
- int (*sync_audio_rate)(struct device *, int port, int rate);
+ int (*sync_audio_rate)(struct device *, int port, int pipe,
+ int rate);
- int (*get_eld)(struct device *, int port, bool *enabled,
- unsigned char *buf, int max_bytes);
+ int (*get_eld)(struct device *, int port, int pipe,
+ bool *enabled, unsigned char *buf, int max_bytes);
struct i915_audio_component_audio_ops
- void (*pin_eld_notify)(void *audio_ptr, int port);
+ void (*pin_eld_notify)(void *audio_ptr, int port, int pipe);
This patch makes dummy changes in the audio drivers (thanks Libin) for
build to succeed. The audio side drivers will send the right 'pipe' values
for MST in patches that will follow.
v2:
Renamed the new API parameter from 'dev_id' to 'pipe'. (Jim, Ville)
Included Asoc driver API compatibility changes from Jeeja.
Added WARN_ON() for invalid pipe in get_saved_encoder(). (Takashi)

v3:

v4:

this patch the AFG node is set to D3 and codec power is turned

Also setting power state for AFG node is optimized. With this the
