As for several other exynos devices we need to disable the
video4linux's udev rule OR disable FIMC IS and patch kernel to fix
build error without FIMC IS.
Add dependency on postmarketos-base-downstream-disable-udev-v4l to
override the v4l rule with symlink to /dev/null. We can then drop
FIMC IS patch and keep kernel config more similar to original one.
Simply disabling FIMC IS does not work however due to compilation
errors and a null pointer dereference. 01-fix-FIMC-IS-disabling.patch
takes care of this.
As with other exynos devices some additional things had to be disabled
to make the kernel compile after FIMC IS had been disabled,
specifically:
CONFIG_CAMERA_EEPROM
CONFIG_VIDEO_EXYNOS_MIPI_CSIS
CONFIG_LEDS_MAX77803
Apart from that we also have:
02-netfilter-symbols.patch, which fixes another compilation error.
03-usb_gadget-set-random-rndis-host-MAC-address-to-prev.patch (taken
from another device) which prevents host mac address being set to
00:00:00:00:00.
Kernel sources have been changed to the lineage-16.0 branch in the
exynos5420 repo, as that is where development happens at the moment.
