Bug#828818: Same issue on a LAMINA 2-in-1 tablet
I'm having the same issue on a LAMINA tablet.
A collegue has a similar tablet with Mint on it, that one has
INTEL_SOC_PMIC_CHTDC_TI built as a module (it can be seen with lsmod).
It seems this module is not built in Debian.
The following could maybe be relevant:
# CONFIG_INTEL_SOC_PMIC_CHTWC is not set
# CONFIG_INTEL_SOC_PMIC_CHTDC_TICONFIG_INTEL_SOC_PMIC_CHTDC_TICONFIG_IN
TEL_SOC_PMIC_CHTDC_TI is not set
I think these are for different controllers.
I tried enabling CONFIG_INTEL_SOC_PMIC_CHTDC_TI as a module, but upon
booting the newly installed kernel it panics (I think it can't find the
boot file system, not sure how to properly do this, or if I did
something wrong).
Also screen brightness is non-working, in the boot log I can see
something about "Failed to own the pwm chip". Also suspend/resume is
very flaky, sometimes it works once, but then never wakes up (actually
I think it's still running, as the battery seems to drain), maybe this
is somehow related to power management or that it fails turning on the
screen again.
