6cfae0c26b Char/Misc driver patches for 5.4-rc1
Here is the big char/misc driver pull request for 5.4-rc1.
 
 As has been happening in previous releases, more and more individual
 driver subsystem trees are ending up in here.  Now if that is good or
 bad I can't tell, but hopefully it makes your life easier as it's more
 of an aggregation of trees together to one merge point for you.
 
 Anyway, lots of stuff in here:
 	- habanalabs driver updates
 	- thunderbolt driver updates
 	- misc driver updates
 	- coresight and intel_th hwtracing driver updates
 	- fpga driver updates
 	- extcon driver updates
 	- some dma driver updates
 	- char driver updates
 	- android binder driver updates
 	- nvmem driver updates
 	- phy driver updates
 	- parport driver fixes
 	- pcmcia driver fix
 	- uio driver updates
 	- w1 driver updates
 	- configfs fixes
 	- other assorted driver updates
 
 All of these have been in linux-next for a long time with no reported
 issues.

4a79ce748f interconnect patches for 5.4
Here are the interconnect driver updates for the 5.4-rc1 merge window.
 
 - New feature is the path tagging support that helps with grouping and
 aggregating the bandwidth requests into separate buckets based on a tag.
 - The first user of the path tagging is the Qualcomm sdm845 driver that
 now implements support for wake/sleep sets. This allows consumer drivers
 to express their bandwidth needs for the different CPU power states.
 - New interconnect driver for the qcs404 platforms and a driver that
 communicates bandwidth requests with remote processor over shared memory.
 - Cleanups and fixes.

ec2da07ca1 memory: mtk-smi: Get rid of need_larbid
The "mediatek,larb-id" has already been parsed in MTK IOMMU driver.
It's no need to parse it again in SMI driver. Only clean some codes.
This patch is fit for all the current mt2701, mt2712, mt7623, mt8173
and mt8183.

After this patch, the "mediatek,larb-id" only be needed for mt2712
which have 2 M4Us. In the other SoCs, we can get the larb-id from M4U
in which the larbs in the "mediatek,larbs" always are ordered.

Correspondingly, the larb_nr in the "struct mtk_smi_iommu" could also
be deleted.

174ae4e96e ARCv2: IDU-intc: Add support for edge-triggered interrupts
This adds support for an optional extra interrupt cell to specify edge
vs level triggered. It is backward compatible with dts files with only
one cell, and will default to level-triggered in such a case.

Note that I had to make a change to idu_irq_set_affinity as well, as
this function was setting the interrupt type to "level" unconditionally,
since this was the only type supported previously.

4d2e26a38f docs: powerpc: convert docs to ReST and rename to *.rst
Convert docs to ReST and add them to the arch-specific
book.

The conversion here was trivial, as almost every file there
was already using an elegant format close to ReST standard.

The changes were mostly to mark literal blocks and add a few
missing section title identifiers.

One note with regards to "--": on Sphinx, this can't be used
to identify a list, as it will format it badly. This can be
used, however, to identify a long hyphen - and "---" is an
even longer one.

At its new index.rst, let's add a :orphan: while this is not linked to
the main index.rst file, in order to avoid build warnings.

5d1d046e28 soc: fsl: qbman_portals: add APIs to retrieve the probing status
Add a couple of new APIs to check the probing status of the required
cpu bound qman and bman portals:
 'int bman_portals_probed()' and 'int qman_portals_probed()'.
They return the following values.
 *  1 if qman/bman portals were all probed correctly
 *  0 if qman/bman portals were not yet probed
 * -1 if probing of qman/bman portals failed
Portals are considered successful probed if no error occurred during
the probing of any of the portals and if enough portals were probed
to have one available for each cpu.
The error handling paths were slightly rearranged in order to fit this
new functionality without being too intrusive.
Drivers that use qman/bman portal driver services are required to use
these APIs before calling any functions exported by these drivers or
otherwise they will crash the kernel.
First user will be the dpaa1 ethernet driver, coming in a subsequent
patch.

Trusted Firmware-A (TF-A) for rk3399 implements a SiP call to get the
on-die termination (ODT) and auto power down parameters from kernel,
this patch adds the functionality to do this. Also, if DDR clock
frequency is lower than the on-die termination (ODT) disable frequency
this driver should disable the DDR ODT.

This patch adds driver for Tegra210 BPMP firmware.

The BPMP is a specific processor in Tegra210 chip, which runs firmware
for assisting in entering deep low power states (suspend to ram), and
offloading DRAM memory clock scaling on some platforms.

Automatically add a device link between the actual device requesting the
dpaa2_io_service_register and the underlying dpaa2_io used. This link
will ensure that when a DPIO device, which is indirectly used by other
devices, is unbound any consumer devices will be also unbound from their
drivers.

For example, any DPNI, bound to the dpaa2-eth driver, which is using
DPIO devices will be unbound before its supplier device.

Also, add a new parameter to the dpaa2_io_service_[de]register functions
to specify the requesting device (ie the consumer).

991e873223 soc: fsl: dpio: use a cpumask to identify which cpus are unused
The current implementation of the dpio driver uses a static next_cpu
variable to keep track of the index of the next cpu available. This
approach does not handle well unbinding and binding dpio devices in a
random order. For example, unbinding a dpio and then binding it again
with the driver, will generate the below error:

$ echo dpio.5 > /sys/bus/fsl-mc/drivers/fsl_mc_dpio/unbind
$ echo dpio.5 > /sys/bus/fsl-mc/drivers/fsl_mc_dpio/bind

NR_CPUS.
[  103.955157] fsl_mc_dpio dpio.5: fsl_mc_driver_probe failed: -34
-bash: echo: write error: No such device

Fix this error by keeping a global cpumask of unused cpus that will be
updated at every dpaa2_dpio_[probe,remove].

4a598c7b3f soc/tegra: Changes for v4.21-rc1
These changes are mostly cleanups to the PMC driver, but they also add
