Motorola Droid 4/Modem

Modem modules & integration with latest kernel + patches:

01:17 < tmlind_> you need to modprobe snd-soc-cpcap, snd-soc-motmdm, and then snd-soc-audio-graph-card
01:17 < tmlind_> try this led backlight series:
01:17 < tmlind_> https://lists.freedesktop.org/archives/dri-devel/2019-October/238988.html
01:17 < tmlind_> you may need to add something to the dts file too, not sure
01:18 < tmlind_> something to tell whichc led is the backlight, the binding patch should have info about it
01:18 < Wizzup> mhm, ok.
01:19 < tmlind_> for modem, you want phy-mapphone-mdm6600 and ohci-platform loaded, then the snd-soc drivers above
01:19 < tmlind_> oh and motorola-mdm too
01:20 < tmlind_> and for idling ohci when not in use, you want to configure /etc/udev/rules.d/ file with:
01:20 < tmlind_> ACTION=="add", SUBSYSTEM=="usb", ATTRS{idVendor}=="22b8", ATTRS{idProduct}=="2a70", TEST=="power/control"
                 ATTR{power/control}="auto"
01:21 < tmlind_> and you probably also need some entry for the /dev/motmdm* file permissions there too
