[PATCH] arm64: dts: qcom: sdm850-lenovo-yoga-c630: enable sensors DSP

Posted by Dmitry Baryshkov 6 months, 2 weeks ago

Enable SLPI, Sensors DSP on the Lenovo Yoga C630. The DSP boots the
firmware and provides QMI services, however it is of limited
functionality due to the missing fastrpc_shell_1 binary.

Check if the Flex 5G's signing key is different (or maybe Lenovo
had more sdm850 models?)

Flex5G is SC8180X, so it probably won't help.

Also, if we check the later generations (e.g. Slim7x and T14s),
different laptop models use different CAs.
