+- Copy IPU6 drivers to kernel source:

+	cp include/uapi/linux/ipu-psys.h <your-kernel>/include/uapi/linux/
+	```
+
+- Copy I2C sensor drivers to kernel source (depending on your need):
+	```sh
+	# Remove ipu6-drivers/drivers/media/i2c/{Kconfig,Makefile}
+	# as corresponding files in your kernel was changed by patches before
+	rm drivers/media/i2c/Kconfig drivers/media/i2c/Makefile
+	cp -r drivers/media/i2c <your-kernel>/drivers/media/
 	```
-- For kernel v6.8. patch/v6.8/0002-media-Add-IPU6-and-supported-sensors-config.patch will change the related Kconfig & Makefile.
-- For kernel v6.10. patch/v6.10/in-tree-build/0001-workaround-patch-to-build-psys.patch will change the Makefile to build IPU6 PSYS driver.
-- For latest linux-firmware repo, apply patch/linux-firmware/0001-Add-symbolic-link-for-Intel-IPU6-firmwares.patch to it to make driver work.
-- For kernel v6.10 and above, copy only drivers you need to kernel source:
-```sh
-# Out-Of-Tree IPU6 PSYS driver
-cp -r drivers/media/pci/intel/ipu6/psys <your-kernel>/drivers/media/pci/intel/ipu6/
-cp include/uapi/linux/ipu-psys.h <your-kernel>/include/uapi/linux/
-# Out-Of-Tree I2C sensor drivers
-cp -r drivers/media/i2c <your-kernel>/drivers/media/i2c
-```
-- For kernel version less than v6.10, copy `drivers` and `include` folders to kernel source **(except Kconfig & Makefile at drivers/media/pci/intel and drivers/media/i2c as they are modified by patches in previous step. You can delete them before you copy folders.)**.
