Hi, Takashi I use git to generate patches. (I run git-fetch origin, git-fetch-rebase origin, and git-format-patch origin)
There are two patch, one for the addition of HDMI, and one for the fix for our aza controller.
Please check it.
Thanks

Hi, Takashi
About the "long delay", it seemed that we need to add this "delay" to fix some issue on our aza controller. Because it related with the controller, not just codec, so I think
this
flag should not be added in codec-initialization part. I think it's better to add the flag in that place which I submitted.
OK, then could you split the patch to separate ones, i.e. one for the fix for this problem regarding Nvidia controller chip, and one for the addition of HDMI?
Don't forget to add a proper description for each patch, please ;)
As mentioned, that flag is a last resort, and I think it can be fixed in a saner way. But, the flag is surely safe, and we can track down the problem later on.
thanks,
Takashi
Thanks

Thanks for your reply.
About the "long delay", we had some problems on reading RIRB buffer
when
testing this driver, so we add this "delay" We will try to find a best way to fix this issue.
And we didn't familiar with git, we will research it more such as "rebase" and then submit the patch file again.
Thanks

Thanks!
But, the patch looks like no "rebase". You secretly added a new function call that wasn't in your previous patch, namely...

This flag is the last resort and should be avoided as much as possible. This results in a significant slow down of suspend/resume speed, for example.
If it's really needed with some devices and there is no other way to fix it, add this flag rather in the codec-initialization part.
Also, if you resend a patch, please add the original patch description
again. This helps my patch work a lot indeed.
thanks,
Takashi
