Rich Graph Card settings is a little bit difficult for beginner,
and Customizing it also difficult/confusable too.
So, this patch adds sample for it.
You can easily use it by adding below line on your DT file,
and select CONFIGs to your .config.
#include "../../../../../sound/soc/generic/rich-graph-card-sample.dtsi"
CONFIG_SND_RICH_GRAPH_CARD
CONFIG_SND_RICH_CUSTOM_CARD_SAMPLE
CONFIG_SND_TEST_COMPONENT
This patch uses rich-graph-card base sample custom driver.
You can directly use rich-graph-card instead of custom driver
by modifing compatible.
- compatible = "rich-custom-card-sample";
+ compatible = "rich-graph-card";
Sample custom driver will indicate customized print.
It is using Test-Component driver for CPU/Codec.
It can indicate more detail print of each behavior if user want to.
In such case, you need to update compatible to "xxx-nv" or "xxx-vv".
- compatible = "test-cpu";
+ compatible = "test-cpu-nv";
