MSM8998 (or Snapdragon 835) is a high-end Qualcomm SoC released in 2017 with mainline support originally added for the MTP (proven reference design) board towards the end of 2018.

UFS internal storage
To enable the device's internal UFS 2.1 host controller (& 14nm UFS QMP PHY), compile the kernel with the following modules enabled:
CONFIG_SCSI_UFS_QCOM=y CONFIG_PHY_QCOM_QMP=y CONFIG_PHY_QCOM_UFS=y
You can optionally set CONFIG_SCSI_SCAN_ASYNC=y
for some additional speedup while booting. Consider also enabling CONFIG_QFMT_V2
if you intend on writing data to a userdata
partition formatted by Android where disk quotas are normally enabled by default for ext4
volumes.
Bluetooth
Getting Bluetooth to work should be trivial assuming you compile the kernel with the following modules enabled:
CONFIG_RFKILL=m CONFIG_BT_RFCOMM=y CONFIG_BT_BNEP=y CONFIG_BT_HIDP=y CONFIG_BT_HS=y CONFIG_BT_LE=y
After those are set and you've copied the needed kernel modules over to the rootfs in /lib/modules/
you just need the following firmware files in /lib/firmware/qca/
:
crbtfw21.tlv crnv21.bin
Those can be supplied directly from linux-firmware
and they should work fine, but if not you'll need to grab the files from your device's firmware partitions.
