d2dee94b66 greybus: es2: implement flush callback
Implement the flush callback which is called as part of connection tear
down to flush host-device queues and stop any ongoing transfers.

Note that this should be considered an optimisation of sort since if
the CPort is stuck waiting for credit, the CPort is likely still stuck
when we try to send the cport_shutdown request over it after the
callback returns.

6ac9166d4e greybus: power_supply: fix name setting location
We were checking for existing power supply names in the wrong place,
i.e, we were checking before any of the module power supply were
registered, because of that of course no name collision was detected.

Move the check to the register loop and with that we guarantee that this
mechanism works for greybus power supply naming.

Tested: using gbsim and using power supply with the same name and check
that: 1. no problems creating sysfs entries; 2. naming is done following
the desired rules.

cc43368a3c greybus: lights: Control runtime pm suspend/resume on AP side
According to runtime pm architecture, the kernel side driver should be
as smart as needed to know when the module is idle or active, so that it can
issue the suspend/resume operations to the firmware side at the right time.
To add logics prevents AP from issuing the suspend request to the firmware
when a channel turning to active state, and put it to suspend if the state
is going to inactive with still holding a reference.

be67e7e54b greybus: svc: drop unnecessary symbol exports
The svc functions are only supposed to be called by core and should not
be exported.

Most of these functions should never have been exported in the first
place, while a few no longer needs to be (e.g. since core gained support
for offloaded connections).

The only remaining exception is gb_svc_intf_set_power_mode() which is
needed by the camera driver until proper link management is in place.

When we receive a update request we shall not trust the cache mechanism
and for that we need a way to invalidate the cache. Add a field that
will control the cache status and refactor the code to check if cache is
valid in a helper function.

the cache expiration time after a previous update as happened and would
be ignored.

5f66d62e83 greybus: power_supply: fix update interval check at request handler
We use the update interval to control the remove path and we set it to
zero when we do not want to have more updates in transit. That means
that the check in the request handler needs to be for interval update
zero to discard the newly received request and not the other way around
like it is.

This will fix the issue that all incoming requests were being discard.

it can disable vibrator until timeout. But after Runtime PM control added

task will be interrupted by suspending event.

Because of this problem, the module can not be in charge of counting down

60e7327d54 greybus: audio: Find data connection based on id
Currently we are using dai->name to identify data connection from list
for a module. Now since we are enabling data path based on widget,
dai->name might be invalid by the time driver receives disable request
for a widget. So, use id fetched from AIF widget->sname to identify data
connection for a module.
