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 is functionally identical but simpler and slightly faster.
The PU domain is turned on at boot time and never turned off. In the
current implementation the pm core will repeatedly call power_off when
the domain is unused and get -EBUSY back. If the domain is marked as
"always on" instead the pm core won't even attempt to turn it off.
In theory on 6qp it is safe to turn PU off in suspend, however that is
best accomplished with a new core flag.

Merge tag 'arm-soc/for-4.19/drivers' of https://github.com/Broadcom/stblinux into next/drivers
This pull request contains Broadcom ARM/ARM64/MIPS SoCs drivers changes
for 4.19, please pull the following:
- Doug updates the low-level suspend/resume code for ARM SoCs to support
the latest rev B3.0 memory controllers found on newer chips with an
appropriate match structure to perform the correct entry sequencing
- Florian updates the Device Tree binding document for these memory
controllers to list all possible compatible strings that exist given
the supported memory controllers.
- Stefan adds the GET_THROTTLED firmware property value that is required
for the Rasperry Pi voltage monitoring driver and updates the
Raspberry Pi firmware driver accordingly to register such a device
using the HWMON subsystem. Finally he adds support for reporting under
voltage conditions using a specialized HWMON driver.

Instead of checking the return value of platform_get_resource(), we can
use devm_ioremap_resource() which has the NULL pointer check and the
memory region requesting. devm_ioremap_resource is designed to replace
calls to devm_request_mem_region followed by devm_ioremap, so let's use
the same.

The imx6sl chip errata document describes ERR006287 like this:
> Upon resuming from power gating, the modules in the display power domain
(eLCDIF, EPDC, PXP and SPDC) might fail to perform register reads
correctly.
> When the modules listed above are used, do not use power gating on the
display power domain.
Link: https://www.nxp.com/docs/en/errata/IMX6SLCE.pdf#page=62
Handle this in the safest possible way by keeping the DISP domain
always-on.

The Reset Controller should be registered in the end of probe, otherwise
Memory Controller device goes away if IRQ requesting fails and the Reset
Controller stays registered. To avoid having to unwind the MC probing in
a case of SMMU probe failure, let's simply print the error message without
failing the MC probe. This allows us to just move the Reset Controller
registering before the SMMU registration, reducing code churning. Also
let's not fail MC probe in a case of Reset Controller registration failure
as it doesn't prevent the MC driver to work.

This pull request brings in the new HWMON driver for getting
under-voltage detection from the Raspberry Pi firmware, and a change
from Kees to remove another instance of VLA stack usage.
Signed-off-by: Florian Fainelli <f.fainelli@gmail.com>
In the quest to remove all stack VLA usage from the kernel[1], this
removes the VLA in favor of a maximum size and adds a sanity check.
Existing callers of the firmware interface never need more than 24
bytes (struct gpio_set_config). This chooses 32 just to stay ahead
of future growth.
v2: Fix the length passed to rpi_firmware_property_list (by anholt,
acked by Kees).

Currently there is no easy way to detect undervoltage conditions on a
remote Raspberry Pi. This hwmon driver retrieves the state of the
undervoltage sensor via mailbox interface. The handling based on
Noralf's modifications to the downstream firmware driver. In case of
an undervoltage condition only an entry is written to the kernel log.

The "pi->dom_info" buffer is allocated in init() and it can't be NULL
here. These tests are sort of weird as well because if "pi->dom_info"
was NULL but "domain" was non-zero then it would lead to an Oops.

Everyone gets these #ifdefs wrong, leading to another warning here:
drivers/soc/ti/wkup_m3_ipc.c:547:12: error: 'wkup_m3_ipc_resume' defined but not used [-Werror=unused-function]
static int wkup_m3_ipc_resume(struct device *dev)
drivers/soc/ti/wkup_m3_ipc.c:539:12: error: 'wkup_m3_ipc_suspend' defined but not used [-Werror=unused-function]
static int wkup_m3_ipc_suspend(struct device *dev)
The easiest way to get it right is to remove all the #ifdefs and
let the compiler drop the unused functions silently after we
mark them as __maybe_unused.
