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.

Fix so that FIMC IS can be disabled
|
|
|
|
* mach-exynos: don't set EXYNOS5_{DEV,SETUP}_FIMC_IS for universal5420
|
|
|
|
* board-universal5420-media: add ifdef guard to fix compilation error
|
|
|
|
* pm_domains: always init exynos54xx_pd_isp to prevent null pointer dereference
