The Spreadtrum platform has 2 EIC controllers, one is in digital chip and
another one is in PMIC. The digital-chip EIC controller has 4 sub-modules:
debounce EIC, latch EIC, async EIC and sync EIC, each sub-module can has
multiple groups and each group contains 8 EICs. The PMIC EIC controller has

According to PSCI standard v0.2, for CPU_SUSPEND call, which is
used by cpu idle framework, bit[16] of state parameter must be 0.
So update bit[16] of property 'arm,psci-suspend-param', which is
used as state parameter, to 0.

I2C transfer functions return number of successful operations (on success).
Do not return the received positive return code but instead return 0 on
success. The users of write_reg function already use this logic.

Find the sensor mode by comparing the size of the requested image size
and the sensor mode's image size. The distance between image sizes is the
size in pixels of the non-overlapping regions between the requested size
and the frame-specified size. This logic is borrowed from et8ek8 sensor

Banana Pi M2 Zero board is a H2+-based board by Sinovoip, with a form

It features:

- MicroSD slot
- Two MicroUSB Type-B ports (one can only be used
This patch adds support to walk through the free page blocks in the
system and report them via a callback function. Some page blocks may
leave the free list after zone->lock is released, so it is the caller's
responsibility to either detect or prevent the use of such pages.

This patch series is separated from the previous "Virtio-balloon
Enhancement" series. The new feature, VIRTIO_BALLOON_F_FREE_PAGE_HINT,
implemented by this series enables the virtio-balloon driver to report
hints of guest free pages to the host. It can be used to accelerate live
migration of VMs.
Negotiation of the VIRTIO_BALLOON_F_FREE_PAGE_HINT feature indicates the
support of reporting hints of guest free pages to host via virtio-balloon.
Host requests the guest to report free page hints by sending a new cmd
id to the guest via the free_page_report_cmd_id configuration register.

Move the PAGE_POISON value to page_poison.c and add a function to enable
callers from a kernel module to get the poison value if the page poisoning
feature is in use. This also avoids callers directly checking PAGE_POISON
regardless of whether the feature is enabled.

The VIRTIO_BALLOON_F_PAGE_POISON feature bit is used to indicate if the
guest is using page poisoning. Guest writes to the poison_val config
field to tell host about the page poisoning value in use.

Hi Linus!
Please pull the below for the only change I had in the CRIS tree for 4.16.
It looks as there was som breakage in 4.15-rc3 for CRIS, which I'll send
as a separate pull-request based on 4.15 asap.
