[PATCH 0/4] ASoC: qcom: display port changes

[srinivas.kandagatla]

From: Srinivas Kandagatla <srinivas.kandagatla@linaro.org>

This patchset adds support for.
	1. parse Display Port module tokens from ASoC topology
	2. add support to DP/HDMI Jack events.
	3. fixes a typo in function name in sm8250

Verified these patches on X13s along with changes to tplg in 
https://git.codelinaro.org/linaro/qcomlt/audioreach-topology/-/tree/topic/x13s-dp?ref_type=heads
and ucm chagnes from https://github.com/Srinivas-Kandagatla/alsa-ucm-conf/tree/topic/x13s-dp

Thanks,
Srini

[PATCH 1/4] ASoC: qcom: q6dsp: parse Display port tokens

[srinivas.kandagatla]

From: Srinivas Kandagatla <srinivas.kandagatla@linaro.org>

DP Module needs to know the data format type which is specified in the
tplg file, parse that info before setting up the module.
