4c87f3ff78 Arm SCMI updates for v6.4 
The main and only new addition this time around is the support for
 unidirectional mailbox channels. SCMI communicates between the agent
 and the platform using one bidirectional 'a2p' channel used by the agent
 to send SCMI commands and synchronously receive the related replies, and
 an optional 'p2a' unidirectional channel used to asynchronously receive
 delayed responses and notifications emitted from the platform.
 
 In order to support platforms that support only unidirectional mailbox
 hardware channels, the existing bindings are extended to support the
 same. Both bidirectional and unidirectional channels support for the
 SCMI mailbox can coexist. The correct and effective combination of
 defined 'mboxes' and 'shmem' descriptors determines the type of the
 mailbox channel.
 
 This also contains a fix for the transfers allocation on Rx channel
 especially when the base protocol doesn't use Rx channel while some
 of the protocols can have dedicated Rx channels.

04523aceae soc: ti: smartreflex: Simplify getting the opam_sr pointer 
The probe function stores the sr_info pointer using
platform_set_drvdata(). Use the corresponding platform_get_drvdata() to
retrieve that pointer in the remove and shutdown functions.

This simplifies these functions and makes error handling unnecessary.
This is a good thing as at least for .remove() returning an error code
doesn't have the desired effect.

This is a preparation for making platform remove callbacks return void.

aebe916f9e A few more Qualcomm driver updates for v6.4 
This introduces a new binding and a dedicated driver for the Qualcomm
 Inline-Crypto-Engine (ICE), in order to support a single shared instance
 between SDHCI and UFS, found in recent platforms.
 
 RSC version check is updated to support minor revisions of v3 of the ip
 block, the SMD-RPM interface is transitioned to GFP_ATOMIC to avoid the
 shrinker to kick in underneath the GPU and QCM2290 support is added to
 the SCM binding.

Merge tag 'qcom-drivers-for-6.4-2' of https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux into soc/drivers

A few more Qualcomm driver updates for v6.4

This introduces a new binding and a dedicated driver for the Qualcomm
Inline-Crypto-Engine (ICE), in order to support a single shared instance
between SDHCI and UFS, found in recent platforms.

RSC version check is updated to support minor revisions of v3 of the ip
block, the SMD-RPM interface is transitioned to GFP_ATOMIC to avoid the
shrinker to kick in underneath the GPU and QCM2290 support is added to
the SCM binding.

126c6da71f Qualcomm driver updates for v6.4 
The Qualcomm SCM driver will now always clear the download bit, avoiding
 entering download mode on a clean reboot because the bootloader left it
 set. The vmid bitmap passed to qcom_scm_assign_mem() is transitioned to
 a well defined size. SM6375 support is added, and SC8180X,
 QDU1000/QRU1000, IPQ5332 and IPQ9574 compatibles are documented.
 
 GENI gains support for newer hardware with deeper FIFOs.
 
 The BWMON driver is updated to better handle the two register blocks,
 which are not consistent between MSM8998 and newer platforms.
 
 The LLCC driver no longer assumes a fixes stride across the various
 banks, and instead acquire the bank placement from DeviceTree. EDAC
 support for polling is introduced. EDAC support on SDM845 is disabled,
 as its been observed that accessing relevant registers is not permitted
 on most devices.
 
 PMIC GLINK is reworked to support defining which auxiliary children to
 spawn per platform, support for spawning a UCSI child is added and
 SM8450 and SM8550 is introduced.
 
 The RPM power-domain driver is cleaned up by moving and generalizing
 structures that are common between platforms, rather than duplicating
 everything. Macros are replaced with just direct definition of the
 relevant structures. Support for defining parent relationships between
 the power-domains is introduced, like it has been in rpmhpd for a long
 time.
 
 Number of processors has gone up, so max processor count in SMEM
 is bumped again. Error handling in SMSM is cleaned up using
 dev_err_probe().
 
 Socinfo is taught about IPQ9574, QCM2290, QRB2210, QRB4210, SM7150,
 SA8775P and a number of PMICs.

3d3b32a6dd RISC-V SoC drivers for v6.4 
Microchip:
 Mailbox controller & client changes for the system controller on
 PolarFire SoC. The controller bits have been acked by Jassi.
 Primarily the changes work around a "hardware" bug (really the system
 controller's software, but it may as well be hardware as customers
 cannot change it) where interrupts are not generated if a service fails.
 The mailbox controller driver is tweaked to use polling, rather than
 interrupt, mode and there are some changes to timeout code required in
 the client driver as a result. There's some opportunistic cleanup that I
 performed while doing the swap too.
 
 Canaan:
 A single fix for some randconfig issues that crop up when !mmu is
 enabled for 32-bit kernels, due to my changes in a previous release that
 swapped out select based entablement of the driver.

2afbf43a4a soc: qcom: Make the Qualcomm UFS/SDCC ICE a dedicated driver 
This takes the already existing duplicated support in both ufs-qcom
and sdhci-msm drivers and makes it a dedicated driver that can be used
by both mentioned drivers.

The reason for this is because, staring with SM8550, the ICE IP block
is shared between UFS and SDCC, which means we need to probe a dedicated
device and share it between those two consumers.

So let's add the ICE dedicated driver as a soc driver.

Platforms that already have ICE supported, will use it as a library
as the of_qcom_ice_get will return an ICE instance created for the
consumer device. This allows the backwards compatibility with old-style
devicetree approach.

Also, add support to HW version 4.x since it works out-of-the-box with
the current driver. The 4.x HW version is found on SM8550 platform.

suspend/resume path vs shrinker/reclaim in the following patches, we
need to avoid allocations that can trigger reclaim in the icc_set_bw()

it should be reasonable to use in the smd-rpm case as well.

Alternatively, 256bytes is small enough for a function that isn't called

92ac94f7e1 dt-bindings: firmware: arm,scmi: Support mailboxes unidirectional channels 
SCMI defines two kinds of communication channels between the agent and the
platform: one bidirectional 'a2p' channel used by the agent to send SCMI
commands and synchronously receive the related replies, and an optional
'p2a' unidirectional channel used to asynchronously receive delayed
responses and notifications emitted from the platform.

When configuring an SCMI transport based on mailboxes, the current binding
supports only mailboxes providing bidirectional channels: in such a case
one mailbox channel can be easily assigned to each SCMI channel as above
described.

In case, instead, to have to deal with mailboxes providing only distinct
unidirectional channels, it becomes necessary to extend the binding in
order to be able to bind 2 distinct unidirectional mailbox channels to the
same SCMI 'a2p' channel.

Bidirectional and unidirectional channels support for the SCMI mailbox
transport can coexist by carefully considering the effective combination
of defined 'mboxes' and 'shmem' descriptors.

8c47b8253f firmware: Use of_property_present() for testing DT property presence 
It is preferred to use typed property access functions (i.e.
of_property_read_<type> functions) rather than low-level
of_get_property/of_find_property functions for reading properties. As
part of this, convert of_get_property/of_find_property calls to the
recently added of_property_present() helper when we just want to test
for presence of a property and nothing more.

b6e9fb7ac2 soc: qcom: icc-bwmon: Handle global registers correctly 
The BWMON hardware has two sets of registers: one for the monitor itself
and one called "global". It has what seems to be some kind of a head
switch and an interrupt control register. It's usually 0x200 in size.

On fairly recent SoCs (with the starting point seemingly being moving
the OSM programming to the firmware) these two register sets are
contiguous and overlapping, like this (on sm8450):

/* notice how base.start == global_base.start+0x100 */
reg = <0x90b6400 0x300>, <0x90b6300 0x200>;
reg-names = "base", "global_base";

Which led to some confusion and the assumption that since the
"interesting" global registers begin right after global_base+0x100,
there's no need to map two separate regions and one can simply subtract
0x100 from the offsets.

This is however not the case for anything older than SDM845, as the
global region can appear in seemingly random spots on the register map.

Handle the case where the global registers are mapped separately to allow
proper functioning of BWMONv4 on MSM8998 and older. Add specific
compatibles for 845, 8280xp, 7280 and 8550 (all of which use the single
reg space scheme) to keep backwards compatibility with old DTs.

fc187a46a8 soc: renesas: renesas-soc: Release 'chipid' from ioremap() 
Smatch reports:

drivers/soc/renesas/renesas-soc.c:536 renesas_soc_init() warn:
'chipid' from ioremap() not released on lines: 475.

If soc_dev_atrr allocation is failed, function renesas_soc_init()
will return without releasing 'chipid' from ioremap().

Fix this by adding function iounmap().

c3fbced9af soc: bcm: brcmstb: biuctrl: fix of_iomap leak 
Smatch reports:

drivers/soc/bcm/brcmstb/biuctrl.c:291 setup_hifcpubiuctrl_regs() warn:
'cpubiuctrl_base' from of_iomap() not released on lines: 291.

This is because in setup_hifcpubiuctrl_regs(),
cpubiuctrl_base is not released when handle error, which may cause a leak.
To fix this, iounmap is added when handle error.
