Detailed description for patchset:

- extcon-max77843.c driver support the MAXIM MAX77843 MUIC (Micor-USB Interface
Controller) device which handles the various external connectors such as TA/USB
/USB-HOST/JIG and so on.
- extcon-usb-gpio.c driver support the USB and USB-HOST cable detection by
using the GPIO pin which is connected to USB ID pin. This GPIO pin updates the
USB cable states.
2. Rename the filename of extcon core driver and add missing locking mechanism
- Rename the previous extcon-class driver.c as extcon.c because '-class'
postfix is not necessary word.
- extcon core driver (extcon.c) used the raw_notifier_chain. It must be
protected by locking mechanism to avoid the list changing while
extcon_update_state() is executed.
3. Fix minor issue of extcon drviers
- Fix cable name by using the capital letter instead of small letter on
extcon-max77693.c driver.
- Clean-up code of extcon-arizona.c to detect headphone cable.
- Fix the wrong return type and variable type on extcon-max77843.c.
- Fix the checkpatch warning of all extcon drivers.

Add a driver for the NAND/External Memory Controller (NEMC) on JZ4780
and later SoCs.
The primary function of this driver is to configure parameters, such
as timings, for external memory devices using data supplied in the
device tree. Devices connected to the NEMC are represented in the DT
as children of the NEMC node, the driver uses optional properties
specified in these child nodes to configure the parameters of each
bank.

According to spmi spec a slave powers up into startup state and then
transitions into active state. Thus, the wakeup command is not required
before calling the slave's probe. The wakeup command is only needed for
slaves that are in sleep state after receiving the sleep command.

Memory blocks can be onlined in random order. When this order is not natural
some memory pages are not onlined because of the redundant check in
hv_online_page().
Here is a real world scenario:
1) Host tries to hot-add the following (process_hot_add):
pg_start=rg_start=0x48000, pfn_cnt=111616, rg_size=262144
2) This results in adding 4 memory blocks:
[ 109.057866] init_memory_mapping: [mem 0x48000000-0x4fffffff]
[ 114.102698] init_memory_mapping: [mem 0x50000000-0x57ffffff]
[ 119.168039] init_memory_mapping: [mem 0x58000000-0x5fffffff]
[ 124.233053] init_memory_mapping: [mem 0x60000000-0x67ffffff]
The last one is incomplete but we have special has->covered_end_pfn counter to
avoid onlining non-backed frames and hv_bring_pgs_online() function to bring
them online later on.
3) Now we have 4 offline memory blocks: /sys/devices/system/memory/memory9-12
$ for f in /sys/devices/system/memory/memory*/state; do echo $f `cat $f`; done | grep -v onlin
/sys/devices/system/memory/memory10/state offline
/sys/devices/system/memory/memory11/state offline
/sys/devices/system/memory/memory12/state offline
/sys/devices/system/memory/memory9/state offline
4) We bring them online in non-natural order:
$grep MemTotal /proc/meminfo
MemTotal: 966348 kB
$echo online > /sys/devices/system/memory/memory12/state && grep MemTotal /proc/meminfo
MemTotal: 1019596 kB
$echo online > /sys/devices/system/memory/memory11/state && grep MemTotal /proc/meminfo
MemTotal: 1150668 kB
$echo online > /sys/devices/system/memory/memory9/state && grep MemTotal /proc/meminfo
MemTotal: 1150668 kB
As you can see memory9 block gives us zero additional memory. We can also
observe a huge discrepancy between host- and guest-reported memory sizes.
The root cause of the issue is the redundant pg >= covered_start_pfn check (and
covered_start_pfn advancing) in hv_online_page(). When upper memory block in
being onlined before the lower one (memory12 and memory11 in the above case) we
advance the covered_start_pfn pointer and all memory9 pages do not pass the
check. If the assumption that host always gives us requests in sequential order
and pg_start always equals rg_start when the first request for the new HA
region is received (that's the case in my testing) is correct than we can get
rid of covered_start_pfn and pg >= start_pfn check in hv_online_page() is
sufficient.

the bug.
