More Qualcomm driver updates for 5.13

This improves the Qualcomm SCM driver logic related to detecting the
calling convention, in particular on SC7180, and fixes a few small
issues in the same.

It introduces additonal sanity checks of the size of loaded segments in
the MDT loader and adds a missing error in the return path of
pdr_register_listener().

It makes it possible to specify the OEM specific firmware path in the
wcn36xx control (and WiFi) driver.

Lastly it adds a missing path specifier in the MAINTAINERS' entry and
fixes a bunch of kerneldoc issues in various drivers.

311bf0f18c ARM: dts: Remove LPC BMC and Host partitions
The LPC controller has no concept of the BMC and the Host partitions.

A concrete instance is that the HICRB[5:4] are for the I/O port address
configurtaion of KCS channel 1/2. However, the KCS driver cannot access
HICRB for channel 1/2 initialization via syscon regmap interface due to
the parition boundary. (i.e. offset 80h)

In addition, for the HW design backward compatibility, a newly added HW
control bit could be located at any reserved one over the LPC addressing
space. Thereby, this patch removes the lpc-bmc and lpc-host child node
and thus the LPC partitioning.

Note that this change requires the synchronization between device tree
change and the driver change. To prevent the misuse of old devicetrees
with new drivers, or vice versa, the v2 compatible strings are adopted
for the LPC device as listed:

	"aspeed,ast2400-lpc-v2"
	"aspeed,ast2500-lpc-v2"
	"aspeed,ast2600-lpc-v2"

driver to all the users of SCMI and hence involved changes in various
other subsystem SCMI drivers. The change has been split with a bit of

changing all the users.

This also includes SCMI IIO driver(pulled from IIO tree) and support for

257f2935cb firmware: qcom_scm: Workaround lack of "is available" call on SC7180
Some SC7180 firmwares don't implement the QCOM_SCM_INFO_IS_CALL_AVAIL
API, so we can't probe the calling convention. We detect the legacy
calling convention on these firmwares, because the availability call
always fails and legacy is the fallback. This leads to problems where
the rmtfs driver fails to probe, because it tries to assign memory with
a bad calling convention, which then leads to modem failing to load and
all networking, even wifi, to fail. Ouch!

Let's force the calling convention to be what it always is on this SoC,
i.e. arm64. Of course, the calling convention is not the same thing as
implementing the QCOM_SCM_INFO_IS_CALL_AVAIL API. The absence of the "is
this call available" API from the firmware means that any call to
__qcom_scm_is_call_available() fails. This is OK for now though because
none of the calls that are checked for existence are implemented on
firmware running on sc7180. If such a call needs to be checked for
existence in the future, we presume that firmware will implement this
API and then things will "just work".

f6ea568f0d firmware: qcom_scm: Reduce locking section for __get_convention()
We shouldn't need to hold this spinlock here around the entire SCM call
into the firmware and back. Instead, we should be able to query the
firmware, potentially in parallel with other CPUs making the same
convention detection firmware call, and then grab the lock to update the
calling convention detected. The convention doesn't change at runtime so
calling into firmware more than once is possibly wasteful but simpler.
Besides, this is the slow path, not the fast path where we've already
detected the convention used.

More importantly, this allows us to add more logic here to workaround
the case where the firmware call to check for availability isn't
implemented in the firmware at all. In that case we can check the
firmware node compatible string and force a calling convention.

Note that we remove the 'has_queried' logic that is repeated twice. That
could lead to the calling convention being printed multiple times to the
kernel logs if the bool is true but __query_convention() is running on
multiple CPUs. We also shorten the time where the lock is held, but we
keep the lock held around the printk because it doesn't seem hugely
important to drop it for that.

9d11af8b06 firmware: qcom_scm: Make __qcom_scm_is_call_available() return bool
Make __qcom_scm_is_call_available() return bool instead of int. The
function has "is" in the name, so it should return a bool to indicate
the truth of the call being available. Unfortunately, it can return a
number < 0 which also looks "true", but not all callers expect that and
thus they think a call is available when really the check to see if the
call is available failed to figure it out.

This commit was required because at that time, ioread/iowrite

dc67dac617 soc: fsl: guts: fix comment syntax in file
The opening comment mark '/**' is used for kernel-doc comments.
There are certain comments in include/linux/fsl/guts.h which follows this
syntax, but the content inside does not comply with kernel-doc.

E.g., opening comment for "Freecale 85xx and 86xx Global Utilties
register set" follows kernel-doc syntax(i.e., '/**'), but the content
inside does not comply with any kernel-doc specification (function,
struct, etc).

This causes unwelcomed warning from kernel-doc:
"warning: expecting prototype for Freecale 85xx and 86xx Global Utilties register set(). Prototype was for __FSL_GUTS_H__() instead"

Replace all such comment occurrences with general comment format,
i.e. '/*' to pervent kernel-doc from parsing these.

1d79dca631 Merge tag 'omap-for-v5.13/ti-sysc-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into arm/drivers
Driver changes for omaps for genpd support for v5.13

In order to move omap4/5 and dra7 to probe with devicetree data and genpd,
we need to patch the related drivers to prepare.

These are mostly ti-sysc interconnect target module driver changes and soc
init changes. However, there are minor changes to other drivers too. There
are changes for pci-dra7xx probe, omap-prm idle configuration, and a omap5
clock change:

- ti-sysc needs iorange check improved when the interconnect target module
  has no control registers listed

- ti-sysc needs to probe l4_wkup and l4_cfg interconnects first to avoid
  issues with missing resources and unnecessary deferred probe

- ti-sysc debug option can now detect more devices

- ti-sysc now warns if an old incomplete devicetree data is found as we
  now rely on it being complete for am3 and 4

- soc init code needs to check for prcm and prm nodes for omap4/5 and
  dra7

- omap-prm driver needs to enable autoidle retention support for omap4

- omap5 clocks are missing gpmc and ocmc clock registers

- pci-dra7xx now needs to use builtin_platform_driver instead of using
  builtin_platform_driver_probe for deferred probe to work

There are also few minor non-urgent fixes:

- soc init code pdata_quirks_init_clocks should be static

- ti-sysc has few unneeded semiconon typos

- ti-sysc can use kzalloc instead of kcalloc for a single element
