bf18123e78 mailbox: pcc: Avoid accessing PCCT table in pcc_send_data and pcc_mbox_irq
Now that the con_priv is availvale solely for PCC mailbox controller
driver, let us use the same to save the channel specific information
in it so that we can it whenever required instead of parsing the PCCT
table entries every time in both pcc_send_data and pcc_mbox_irq.

We can now use the newly introduces PCC register bundle to simplify both
saving of channel specific information and accessing them without repeated
checks for the subspace type.

800cda7b63 mailbox: pcc: Add PCC register bundle and associated accessor functions
Extended PCC subspaces introduces more registers into the PCCT. In order
to consolidate access to these registers and to keep all the details
contained in one place, let us introduce PCC register bundle that holds
the ACPI Generic Address Structure as well as the virtual address for
the same if it is mapped in the OS.

It also contains the various masks used to access the register and
the associated read, write and read-modify-write accessors.

We can also clean up the initialisations by having a helper function
for the same.

7b6da7fe7b mailbox: pcc: Use PCC mailbox channel pointer instead of standard
Now that we have all the shared memory region information populated in
the pcc_mbox_chan, let us propagate the pointer to the same as the
return value to pcc_mbox_request channel.

This eliminates the need for the individual users of PCC mailbox to
parse the PCCT subspace entries and fetch the shmem information. This
also eliminates the need for PCC mailbox controller to set con_priv to
PCCT subspace entries. This is required as con_priv is private to the
controller driver to attach private data associated with the channel and
not meant to be used by the mailbox client/users.

Let us convert all the users of pcc_mbox_{request,free}_channel to use
new interface.

0f2591e21b mailbox: pcc: Add pcc_mbox_chan structure to hold shared memory region info
Currently PCC mailbox controller sets con_priv in each channel to hold
the pointer to pcct subspace entry it corresponds to. The mailbox user
will then fetch this pointer from the channel descriptor they get when
they request for the channel. Using that pointer they then parse the
pcct entry again to fetch all the information about shared memory region.

In order to remove individual users of PCC mailbox parsing the PCCT
subspace entries to fetch same information, let us consolidate the same
in pcc mailbox controller by parsing all the shared memory region
information into a structure that can also hold the mbox_chan pointer it
represent.

This can then be used as main PCC mailbox channel pointer that we can
return as part of pcc_mbox_request_channel instead of standard mailbox
channel pointer.

4e3c96ff95 mailbox: pcc: Consolidate subspace doorbell register parsing
Extended PCC subspaces(Type 3 and 4) differ from generic(Type 0) and
HW-Reduced Communication(Type 1 and 2) subspace structures. However some
fields share same offsets and same type of structure can be use to
extract the fields. In order to simplify that, let us move all the doorbell
register parsing into pcc_parse_subspace_db_reg and consolidate there.
It will be easier to extend it if required within the same.

80b2bdde00 mailbox: pcc: Refactor all PCC channel information into a structure
Currently all the PCC channel specific information are stored/maintained
in global individual arrays for each of those information. It is not
scalable and not clean if we have to stash more channel specific
information. Couple of reasons to stash more information are to extend
the support to Type 3/4 PCCT subspace and also to avoid accessing the
PCCT table entries themselves each time we need the information.

This patch moves all those PCC channel specific information into a
separate structure pcc_chan_info.

In the probe function, the clock IDs were pointed to local variables
which should only be used in the same code block, and any access to them
after the probing stage becomes an use-after-free case.

Since there are only limited variants of the gce clock names so far, we
can just declare them as static constants to fix the issue.

f04298169d ARM: SoC fixes for 5.15, part 2
A small number fixes this time, mostly touching actual code:
 
  - Add platform device for i.MX System Reset Controller (SRC) to fix
    a regression caused by fw_devlink change.
 
  - A fixup for a boot regression caused by my own rework for the
    Qualcomm SCM driver.
 
  - Multiple bugfixes for the Arm FFA and optee firmware drivers,
    addressing problems when they are built as a loadable module.
 
  - Four dts bugfixes for the Broadcom SoC used in Raspberry pi, addressing
    VEC (video encoder), MDIO bus controller #address-cells/#size-cells,
    SDIO voltage and PCIe host bridge dtc warnings.

		#error "You should define correct DTCM_RAM_BASE"
   18 | #error "You should define correct DTCM_RAM_BASE"

This is seen with compile tests since those enable HAVE_TCM,
but do not provide useful default values for ITCM_RAM_BASE or
DTCM_RAM_BASE. Disable HAVE_TCM for commpile tests to avoid
the error.

af89ebaa64 csky: Fixup regs.sr broken in ptrace
gpr_get() return the entire pt_regs (include sr) to userspace, if we
don't restore the C bit in gpr_set, it may break the ALU result in
that context. So the C flag bit is part of gpr context, that's why
riscv totally remove the C bit in the ISA. That makes sr reg clear
from userspace to supervisor privilege.

fbd63c08cd csky: don't let sigreturn play with priveleged bits of status register
csky restore_sigcontext() blindly overwrites regs->sr with the value
it finds in sigcontext.  Attacker can store whatever they want in there,
which includes things like S-bit.  Userland shouldn't be able to set
that, or anything other than C flag (bit 0).

Do the same thing other architectures with protected bits in flags
register do - preserve everything that shouldn't be settable in
user mode, picking the rest from the value saved is sigcontext.

985f6ab93f spi: Fixes for v5.15
A few small fixes for v5.15, mostly driver specific but there's one in
 the core which fixes a deadlock when adding devices on spi-mux that's
 triggered because spi-mux is a SPI device which is itself a SPI
 controller and so can instantiate devices when registered.  We were
 using a global lock to protect against reusing chip selects but they're
 a per controller thing so moving the lock per controller resolves that.
