PD#161621: gpio: core: Decouple open drain/source flag with active low/high
Currently, the GPIO interface is said to Open Drain if it is Single
Ended and active LOW. Similarly, it is said as Open Source if it is
Single Ended and active HIGH.
The active HIGH/LOW is used in the interface for setting the pin
state to HIGH or LOW when enabling/disabling the interface.
In Open Drain interface, pin is set to HIGH by putting pin in
high impedance and LOW by driving to the LOW.
In Open Source interface, pin is set to HIGH by driving pin to
HIGH and set to LOW by putting pin in high impedance.
With above, the Open Drain/Source is unrelated to the active LOW/HIGH
in interface. There is interface where the enable/disable of interface
is ether active LOW or HIGH but it is Open Drain type.
Hence decouple the Open Drain with Single Ended + Active LOW and
Open Source with Single Ended + Active HIGH.
Adding different flag for the Open Drain/Open Source which is valid
only when Single ended flag is enabled.
Note: the patch from v4.14-rc6 with original commit ID 4c0facddb

PD#160530: porting hard lockup without nmi support
Emulate NMIs on systems where they are not available by using timer
interrupts on other cpus. Each cpu will use its softlockup hrtimer
to check that the next cpu is processing hrtimer interrupts by
verifying that a counter is increasing.
This patch is useful on systems where the hardlockup detector is not
available due to a lack of NMIs, for example most ARM SoCs.
Without this patch any cpu stuck with interrupts disabled can
cause a hardware watchdog reset with no debugging information,
but with this patch the kernel can detect the lockup and panic,
which can result in useful debugging info.

PD#156734: optimise the clock divider of VID_PLL_DIV
This is a bridge of analog signal and digital signal module.
With VCO output 4.455Gbps/2160p60hzY420 12bits mode and the
ENCP needs 594MHz, there should divide half to reduce the
risk of HHI_VID_PLL_CLK_DIV.

PD#159608: mm: optimize for CMA allocate time
1. Make all amlogic-changed mm code configuarable, which are
wrapped by CONFIG_AMLOGIC_CMA/CONFIG_AMLOGIC_MEMORY_EXTEND
2. Implement some core code of CMA to a single file:
drivers/amlogic/memory_ext/aml_cma.c
3. detailed imporove steps:
a) use NOOP as default IO-scheduler for nand based storage.
which can avoid long time wait for page lock found in
CFQ scheduler;
b) use per-cpu thread to allocate CMA concurrent when driver
request large amount CMA memory; these threads have high
user nice value to reduce schedule delay;
c) increase task user nice of mmc queue and kswapd.
d) wake up kswapd if page are hold by kswap shrink list and
cma isolated test failed.
e) Fobidden low user nice task use CMA, which can avoid priority
inversion problem.
f) optimize for LRU usage, devide each type of LRU to 2 parts,
normal pages are linked after LRU head, CMA pages are linked
after cma_list.
g) avoid compaction case move cma forbidden pages to cma area.
h) Increase strength of lowmemory killer.
4. Improve read speed of /proc/pagetrace, a filter can be set to
reduce message which not print functions allocate memory less
than filter value:
echo filter=xxx > /proc/pagetrace
