Hi,
The simple-card is not common at present, soc maybe need own machine
driver for jack detection.
Add drivers for two families of rockchip-bases chromebooks. These
machine drives don't use simplecard because we need custom jack
detection plumbing.
- use ts3a227e for ext jack detection with max98090
- call rt5645_set_jack_detect function via rt5645 codec driver
Thanks.
