• Added fully support for SM-N910U device, now we have a barebone kernel for (C/H/U)
• Kernel now fully compiled from DTS device tree source

Synapse:

• Added Exynos Core control
• Various ramfs tweaks

##Kernel-V1.3b:## Kernel:

• Increasing throttling freq in device tree source
• Reverted GPU DVFS delay and pm time and GPU "all core on param" to stock value.
• drivers: battery: Add unstable power detection switch to charger controls.
• drivers: battery: extern charge_control to SIOP levels control (screen on charge limits).
• drivers: battery: increase siop limits to higher value, it is fixed the negative Inow value when screen is on and the normal AC charging connected.

Synapse:

• Added AC/Main screen off control under Battery TAB.

##Kernel-V1.3:## Kernel:

• Merged N910CXXU1BNL8 sourcecode from OSRC release.
• Drivers: battery: fully reverted stupid fast_charging driver and make Universal5433 Max77843 charge control (original version thx to Andreilux).
• Mach-Exynos: added exynos-interface for control min/max online SOC core control.
• Varios fixes for workqueue/procfs/mm/iosched/ext4/sched/irq.
• I think the WIFI touchlag has gone away.
• I made Device Tree image file generating script, now we can use a compiled dt.img from our dts source code.

Synapse:

• I added a new TAB to Synapse: HMP: under this TAB we can controlling HMP UP/DOWN migrating thresholds .
• New charge-control interface under Battery TAB: support and fully controlled the normal and the adaptive-fastcharging, USB, and various MHL charging current.

##Kernel-V1.2:## Kernel:

• Input-touchscreen: Added input-booster event (from S6)
• Optimized Makefile

Synapse:

• Fixed GPU always used lowest freq (266-350MHz) at some devices, now 3D performance is restored normally (52-55k in Antutu).

##Kernel-V1.1:## Kernel:

• wireless: dhd: Enable standby ARP and multicast packet filters
• security: SELinux: revert Samsung hard enforcing
• cpufreq: Remember last policy min/max on cluster restart
• HMP: Added HMP_LITTLE_PACKING control from sysfs
• HMP: sched: Clean up hmp_up_threshold checks
• HMP: fix out-of-range CPU possible
• HMP: Do not fork-boost tasks coming from PIDs <= 2
• HMP: Make idle balance behaviour normal when HMP: HMP_LITTLE_PACKING is disabled
• ARM: Mali-T760: disabled min/max lock sysfs
• Various sched/mm/writeback/workqueue fixes
• gpio: sysfs: fix memory leak in gpiod_export_link
• gpio: sysfs: fix memory leak in gpiod_sysfs_set_active_low
• ARM: DMA: ensure that old section mappings are flushed from the TLB
• cpufreq: interactive: merge interactive governor from new G920F source
• input_booster: ported from SM-G920F
• cypress-touchkey: Added input-booster event (from S6)
• misc: Input booster: Allow configurable levels
• Exynos-Thermal: Smoothen throttling levels
• CPUFREQ: EGL: increase booting freq to 1.7GHz
• ARM: enable UNALIGNED_ACCESS

Synapse:

• Added HMP packing mode control for Advanced TAB ( Auto mode will be able to use automatic when you are in POWER_SAVE_MOD in TW ROM, if disabled POWER_SAVE_MOD hmp_little_packing auto disabled so kernel use normal packing (more performance)

##Kernel-V0.1-V1.0:##
