UPSTREAM: spi: rockchip: check requesting dma channel with EPROBE_DEFER

Let's defer probing the driver if the return value of
dma_request_slave_channel is ERR_PTR(-EPROBE_DEFER) instead
of disabling dma capability directly.

 commit ea98491133439773b69345eb9a314fc5f15e07a4)

UPSTREAM: dmaengine: Add transfer termination synchronization support

The DMAengine API has a long standing race condition that is inherent to
the API itself. Calling dmaengine_terminate_all() is supposed to stop and
abort any pending or active transfers that have previously been submitted.
Unfortunately it is possible that this operation races against a currently
running (or with some drivers also scheduled) completion callback.

Since the API allows dmaengine_terminate_all() to be called from atomic
context as well as from within a completion callback it is not possible to
synchronize to the execution of the completion callback from within
dmaengine_terminate_all() itself.

This means that a user of the DMAengine API does not know when it is safe
to free resources used in the completion callback, which can result in a
use-after-free race condition.

This patch addresses the issue by introducing an explicit synchronization
primitive to the DMAengine API called dmaengine_synchronize().

The existing dmaengine_terminate_all() is deprecated in favor of
dmaengine_terminate_sync() and dmaengine_terminate_async(). The former
aborts all pending and active transfers and synchronizes to the current
context, meaning it will wait until all running completion callbacks have
finished. This means it is only possible to call this function from
non-atomic context. The later function does not synchronize, but can still
be used in atomic context or from within a complete callback. It has to be
followed up by dmaengine_synchronize() before a client can free the
resources used in a completion callback.

In addition to this the semantics of the device_terminate_all() callback
are slightly relaxed by this patch. It is now OK for a driver to only
schedule the termination of the active transfer, but does not necessarily
have to wait until the DMA controller has completely stopped. The driver
must ensure though that the controller has stopped and no longer accesses
any memory when the device_synchronize() callback returns.

This was in part done since most drivers do not pay attention to this
anyway at the moment and to emphasize that this needs to be done when the
device_synchronize() callback is implemented. But it also helps with
implementing support for devices where stopping the controller can require
operations that may sleep.

arm: topology: Define TC2 energy and provide it to the scheduler

This patch is only here to be able to test provisioning of energy related
data from an arch topology shim layer to the scheduler. Since there is no
code today which deals with extracting energy related data from the dtb or
acpi, and process it in the topology shim layer, the content of the
sched_group_energy structures as well as the idle_state and capacity_state
arrays are hard-coded here.

This patch defines the sched_group_energy structure as well as the
idle_state and capacity_state array for the cluster (relates to sched
groups (sgs) in DIE sched domain level) and for the core (relates to sgs
in MC sd level) for a Cortex A7 as well as for a Cortex A15.
It further provides related implementations of the sched_domain_energy_f
functions (cpu_cluster_energy() and cpu_core_energy()).

To be able to propagate this information from the topology shim layer to
the scheduler, the elements of the arm_topology[] table have been
provisioned with the appropriate sched_domain_energy_f functions.

UPSTREAM: usb: dwc3: core: improve reset sequence

According to Synopsys Databook, we shouldn't be

necessary. Note that this reduces amount of time
spent on dwc3_probe() by a long margin.

We're still gonna wait for reset to finish for a

4.1.1 Physical CPU Interface:
The effects of reading ICC_IAR0_EL1 and ICC_IAR1_EL1

UPSTREAM: ARM: dts: rockchip: move rk3036 memory definition to board files

The amount of available memory is clearly a board-specific value, so
the core per-soc dtsi should not define a default of any sort.
Therefore move the memory-nodes to the two board files.

Also fix the amount of memory on Kylin (512MB instead of 1GB).
While in most cases the bootloader will override this with the
actual amount of memory, there is no need to keep known wrong values
in the board-dts.
