Similarly to R-Car E3, RZ/G2E doesn't come with automatic
transmission registers, as such it is not considered compatible
with the existing fallback bindings.
Add SoC specific binding compatibility to allow for later
support for automatic transmission.

at24: updates for 4.21
Adding a new compatible for 24c2048.
This patch is based on commit a86caa9ba5 ("pinctrl: msm: fix gpio-hog
related boot issues").
It fixes the issue that the gpio ranges needs to be defined before
gpiochip_add().
Therefore, we also have to swap the order of registering the pinctrl
driver and registering the gpio chip.
You also have to add the "gpio-ranges" property to the pinctrl device
node to get it finally working.

Existing libraries and tracing frameworks work around this kernel
version check by automatically deriving the kernel version from
uname(3) or similar such that the user does not need to do it
manually; these workarounds also make the version check useless
at the same time.
Moreover, most other BPF tracing types enabling bpf_probe_read()-like
functionality have /not/ adapted this check, and in general these
days it is well understood anyway that all the tracing programs are
not stable with regards to future kernels as kernel internal data
structures are subject to change from release to release.
Back at last netconf we discussed [0] and agreed to remove this
check from bpf_prog_load() and instead document it here in the uapi
header that there is no such guarantee for stable API for these
programs.

This patch adds support to run dual pipes simultaneously.
A private ioctl to configure the pipe mode (video or still)
is also implemented.
IPU3 hardware supports a maximum of 2 streams per pipe.
With the support of dual pipes, more than 2 stream outputs
can be achieved.
This helps to support advanced camera features like
Continuous View Finder (CVF) and Snapshot During Video(SDV).
Extend ipu3 IMGU driver to support dual pipes
1. Extend current IMGU device to contain 2 groups
of video nodes and 2 subdevs
2. Extend current css to support 2 pipeline and make
CSS APIs to support 2 pipe
3. Add a v4l2 ctrl to allow user to specify the mode
of the pipe
4. Check media pipeline link status to get enabled
pipes

Merge tag 'tpmdd-next-20181217' of git://git.infradead.org/users/jjs/linux-tpmdd into next-tpm
tpmdd updates for Linux v4.21
From Jarkko:
v4.21 updates:
* Support for partial reads of /dev/tpm0.
* Clean up for TPM 1.x code: move the commands to tpm1-cmd.c and make
everything to use the same data structure for building TPM commands
i.e. struct tpm_buf.
From Mimi:
In Linux 4.19, a new LSM hook named security_kernel_load_data was
upstreamed, allowing LSMs and IMA to prevent the kexec_load
syscall. Different signature verification methods exist for verifying
the kexec'ed kernel image. This pull request adds additional support
in IMA to prevent loading unsigned kernel images via the kexec_load
syscall, independently of the IMA policy rules, based on the runtime
"secure boot" flag. An initial IMA kselftest is included.
In addition, this pull request defines a new, separate keyring named
".platform" for storing the preboot/firmware keys needed for verifying
the kexec'ed kernel image's signature and includes the associated IMA
kexec usage of the ".platform" keyring.
(David Howell's and Josh Boyer's patches for reading the
preboot/firmware keys, which were previously posted for a different
use case scenario, are included here.)

Now, when we have a dedicated uplink representor, the netdev instance
set over the esw manager vport (PF) is of no-use. As such, remove it
once we're on switchdev mode and get it back to life when off switchdev.
This is done by reloading the Ethernet interface as well (we already
do that for the IB interface) from the eswitch code while going in/out
of switchdev mode.
The Eth add/remove entries are modified to act differently when called in
switchdev mode. In this case we only deal with registration of the eth
vport representors. The rep netdevices are created from the eswitch call
to load the registered eth representors.
