Some RSCs may only have sleep and wake TCS, i.e, there is no dedicated
TCS for active mode request, but drivers may still want to make active
requests from these RSCs. In such cases re-purpose the wake TCS to send
active state requests.
The requirement for this is that the driver is aware that the wake TCS
is being repurposed to send active request, hence the sleep and wake
TCSes be invalidated before the active request is sent.

Platform drivers need make a lot of resource state requests at the same
time, say, at the start or end of an usecase. It can be quite
inefficient to send each request separately. Instead they can give the
RPMH library a batch of requests to be sent and wait on the whole
transaction to be complete.
rpmh_write_batch() is a blocking call that can be used to send multiple
RPMH command sets. Each RPMH command set is set asynchronously and the
API blocks until all the command sets are complete and receive their
tx_done callbacks.

Platform drivers that want to send a request but do not want to block
until the RPMH request completes have now a new API -
rpmh_write_async().
The API allocates memory and send the requests and returns the control
back to the platform driver. The tx_done callback from the controller is
handled in the context of the controller's thread and frees the
allocated memory. This API allows RPMH requests from atomic contexts as
well.

Active state requests are sent immediately to the RSC controller, while
sleep and wake state requests are cached in this driver to avoid taxing
the RSC controller repeatedly. The cached values will be sent to the
controller when the rpmh_flush() is called.
Generally, flushing is a system PM activity and may be called from the
system PM drivers when the system is entering suspend or deeper sleep
modes during cpuidle.
Also allow invalidating the cached requests, so they may be re-populated
again.

Sleep and wake requests are sent when the application processor
subsystem of the SoC is entering deep sleep states like in suspend.
These requests help lower the system power requirements when the
resources are not in use.
Sleep and wake requests are written to the TCS slots but are not
triggered at the time of writing. The TCS are triggered by the firmware
after the last of the CPUs has executed its WFI. Since these requests
may come in different batches of requests, it is the job of this
controller driver to find and arrange the requests into the available
TCSes.

Add controller driver for QCOM SoCs that have hardware based shared
resource management. The hardware IP known as RSC (Resource State
Coordinator) houses multiple Direct Resource Voter (DRV) for different
execution levels. A DRV is a unique voter on the state of a shared
resource. A Trigger Control Set (TCS) is a bunch of slots that can house
multiple resource state requests, that when triggered will issue those
requests through an internal bus to the Resource Power Manager Hardened
(RPMH) blocks. These hardware blocks are capable of adjusting clocks,
voltages, etc. The resource state request from a DRV are aggregated
along with state requests from other processors in the SoC and the
aggregate value is applied on the resource.
Some important aspects of the RPMH communication -
- Requests are <addr, value> with some header information
- Multiple requests (upto 16) may be sent through a TCS, at a time
- Requests in a TCS are sent in sequence
- Requests may be fire-n-forget or completion (response expected)
- Multiple TCS from the same DRV may be triggered simultaneously
- Cannot send a request if another request for the same addr is in
progress from the same DRV
- When all the requests from a TCS are complete, an IRQ is raised
- The IRQ handler needs to clear the TCS before it is available for
reuse
- TCS configuration is specific to a DRV
- Platform drivers may use DRV from different RSCs to make requests
Resource state requests made when CPUs are active are called 'active'
state requests. Requests made when all the CPUs are powered down (idle
state) are called 'sleep' state requests. They are matched by a
corresponding 'wake' state requests which puts the resources back in to
previously requested active state before resuming any CPU. TCSes are
dedicated for each type of requests. Active mode TCSes (AMC) are used to
send requests immediately to the resource, while control TCS are used to
provide specific information to the controller. Sleep and Wake TCS send
sleep and wake requests, after and before the system halt respectively.

This adds nodes to SDM845-dtsi for all the I2C ports, all the SPI
ports, and UART9. Note that I2C / SPI / UART are a bit strange on
sdm845 because each "serial engine" has 4 pins associated with it and
depending on which firmware has been loaded into the serial engine
(loaded by the BIOS) the serial engine can behave like an I2C port, a
SPI port, or a UART. As per the landed bindings that means that we
need to create one node for each possible mode that the port could be
in. With 16 serial engines that means 16 x 3 = 48 nodes.
We get away with only creating 33 nodes for now because it seems very
likely that SDM845-based boards will actually all use the same UART
(UART 9) for debug purposes. While another UART could be used for
something like Bluetooth communication we can cross that path when we
come to it. Some documentation that I saw implied that using a UART
for "high speed" communications actually needs yet another different
serial engine firmware anyway.
Note that quick measurements adding all these nodes adds <10k of extra
space per dtb that they're included with. If this becomes a problem
we may need to think of a different way to structure this so that
boards only get the nodes they need (or figure out how to get dtc to
strip 'disabled' nodes). For now it seems OK.
These nodes were programmatically generated with a fairly dumb python
script. See http://crosreview.com/1091631 for the source.
NOTE: at the moment SPI chip select doesn't appear to work in my tests
with the latest posted SPI driver. All testing of SPI with this patch
has been done by hacking SPI to GPIO chip select.

The changes on this series are:
- can.rst: fix a footnote reference;
- crypto_engine.rst: Fix two parsing warnings;
- Fix a lot of broken references to Documentation/*;
- improve the scripts/documentation-file-ref-check script, in order
to help detecting/fixing broken references, preventing
false-positives.
After this patch series, only 33 broken references to doc files are
detected by scripts/documentation-file-ref-check"

This tag contains some small RISC-V updates I'd like to target for 4.18.
They are all fairly small this time. Here's a short summary, there's
more info in the commits/merges.
* A fix to __clear_user to respect the passed arguments.
* Enough support for the perf subsystem to work with RISC-V's ISA
defined performance counters.
* Support for sparse and cleanups suggested by it.
* Support for R_RISCV_32 (a relocation, not the 32-bit ISA).
* Some MAINTAINERS cleanups.
* The addition of CONFIG_HVC_RISCV_SBI to our defconfig, as it's always
present.
I've given these a simple build+boot test.
