Subject: ASoC: audio-graph-port: add link-trigger-order
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=fafc20ded3f4659873c83c2af6d389983d480994;p=users%2Fdwmw2%2Flinux.git

ASoC: audio-graph-port: add link-trigger-order

Sound Card need to consider/adjust HW control ordering based on the
combination of CPU/Codec. The controlling feature is already supported
on ASoC, but Simple Audio Card / Audio Graph Card still not support it.
Let's support it.
