How to tell which drivers are required? For a bare-bones driver build

[Marc Bourgoin]

Heyyo, I've been trying to figure out a good way to tell which drivers are exactly needed for an android device in order to build a kernel and drivers as slim as possible.

I'm working with a LeEco Le Max 2 (x829) with 4GB of RAM and 64GB storage.

I've used Device Info HW app from the Play store to determine a few things like:

Accelerometer BMI160

Als/ps PA22A

Magnetometer AK09915

Gyroscope BMI160

Charger USE PMIC

Sound msm8996tashamtp

SCSI THGLF2G9J8LBATRH

Camera uses: imx230, imx230_lg, img230_sunny, ov8865, ov8865_ofilm

qpnp_pon (/devices/virtual/input/input0)

HDMI CEC User or Deck Control (/devices/virtual/input/input1)

qbt1000_key_input (/devices/virtual/input/input2)

synaptics_dsx (/devices/soc/75ba00.i2c/i2c-12/12-004b/input/input3)

hbtp_vm (/devices/virtual/input/input4)

gpio-keys (/devices/soc/soc:gpio_keys/input/input5)

msm8996-tasha-mtp-snd-card Heatset Jack (/devices/soc/soc:sound-9335/sound/card0/input6)

msm8996-tasha-mtp-snd-card Button Jack (/devices/soc/soc:sound-9335/sound/card0/input7)

But is there another recommended app or way to tell what my device is using and what drivers are required?
