PMP8074 is a companion PMIC to the Qualcomm IPQ8074 series that is
controlled via SPMI.
Add DTSI for it providing GPIO, regulator, RTC and VADC support.
RTC is disabled by default as there is no built-in battery so it will
loose time unless board vendor added a battery, so make it optional.

Commit 5e633302ac ("scsi: lpfc: vmid: Add support for VMID in mailbox
command") introduced allocations for the VMID resources in
lpfc_create_port() after the call to scsi_host_alloc(). Upon failure on the
VMID allocations, the new code would branch to the 'out' label, which
returns NULL without unwinding anything, thus skipping the call to
scsi_host_put().
Fix the problem by creating a separate label 'out_free_vmid' to unwind the
VMID resources and make the 'out_put_shost' label call only
scsi_host_put(), as was done before the introduction of allocations for
VMID.

In sas_ata_task_done(), for commands which complete with error we set the
SATA dev FIS status field with ATA_ERR. In ata_eh_analyze_tf() this would
be interpreted as a HSM error. Set ATA_DRDY, which will lead libata to
judge as a device error, which is a safer bet.

In commit c6b9ef5779 ("[SCSI] pm80xx: NCQ error handling changes") the
driver had support added to handle NCQ errors but much of what is done in
this handling is duplicated from the libata EH.
In that named commit we handle in 2x main steps:
a. Issue read log ext10 to examine and clear the errors
b. Issue SATA_ABORT all command
Indeed, in libata EH, we do similar to above:
a. ata_do_eh() -> ata_eh_autopsy() -> ata_eh_link_autopsy() ->
ata_eh_analyze_ncq_error() -> ata_eh_read_log_10h()
b. ata_do_eh() -> ata_eh_recover() which will issue a device soft reset
or hard reset
Since there is so much duplication, use sas_ata_device_link_abort() which
will abort all pending IOs and kick of ATA EH which will do the steps,
above.
However we will not follow the advisory to send the SATA_ABORT all command
after the autopsy in read log ext10. Indeed, in libsas EH, we already send
a per-task SATA_ABORT command, and this is prior to the ATA EH kicking in
and issuing the read log ext10 in the recovery process. I judge that this
is ok as the SATA_ABORT command does not actually send any protocol on the
link to abort I/O on the other side, so would not change any state on the
disk (for the read log ext10 command).

When an NCQ error occurs, the controller will abnormally complete the I/Os
that are newly delivered to disk, and bit8 in CQ dw3 will be set which
indicates that the SATA disk is in error state. The current processing flow
is to set ts->stat to SAS_OPEN_REJECT and then sas_ata_task_done() will set
FIS stat to ATA_ERR. After analyzing the I/O by ata_eh_analyze_tf(),
err_mask will set to AC_ERR_HSM. If media error occurs for four times
within 10 minutes and the chip rejects new I/Os for four times, NCQ will be
disabled due to excessive errors, which is undesirable.
Therefore, use sas_task_abort() to handle abnormally completed I/Os when
SATA disk is in error state, as these abnormally completed I/Os are already
processed by sas_ata_device_link_abort() and qc->flag are set to
ATA_QCFLAG_FAILED. If sas_task_abort() is used, qc->err_mask will not be
modified in EH. Unlike the current process flow, it will not increase the
count of ECAT_TOUT_HSM and not turn off NCQ. Like other I/Os on the disk
that do not have an error but do not return after the NCQ error, they are
retried after the EH.

When CQ header dw3 SATA_DISK_ERR is set it means this SATA disk is in error
state and the current IPTT is invalid. An invalid IPTT does not correspond
to any slot.
In this scenario, new I/Os that delivered to disk will be rejected by the
controller and all I/Os remaining in the disk should be aborted, which we
add here with the sas_ata_device_link_abort() call.
In hisi_sas_abort_task() we don't want to issue a soft reset as it may
cause info to be lost in the target disk for the ATA EH autopsy. In this
case, just release resources - the disk won't return other I/Os normally
after NCQ Error, so this is safe.

Similar to how AHCI handles NCQ errors in ahci_error_intr() ->
ata_port_abort() -> ata_do_link_abort(), add an NCQ error handler for LLDDs
to call to initiate a link abort.
This will mark all outstanding QCs as failed and kick-off EH.
Note:
A "force reset" argument is added for drivers which require the ATA error
handling to always reset the device.
A driver may require this feature for when SATA device per-SCSI cmnd
resources are only released during reset for ATA EH. As such, we need an
option to force reset to be done, regardless of what any EH autopsy
decides.
The SATA device FIS fields are set to indicate a device error from
ata_eh_analyze_tf().

Userspace can currently write to sysfs to transition sdev_state to RUNNING
or OFFLINE from any source state. This causes issues because proper
transitioning out of some states involves steps besides just changing
sdev_state, so allowing userspace to change sdev_state regardless of the
source state can result in inconsistencies; e.g. with ISCSI we can end up
with sdev_state == SDEV_RUNNING while the device queue is quiesced. Any
task attempting I/O on the device will then hang, and in more recent
kernels, iscsid will hang as well.

Since commit d9820ff ("ARC: mm: switch pgtable_t back to struct page *")
a memory leakage problem occurs. Memory allocated for page table entries
not released during process termination. This issue can be reproduced by
a small program that allocates a large amount of memory. After several
runs, you'll see that the amount of free memory has reduced and will
continue to reduce after each run. All ARC CPUs are effected by this
issue. The issue was introduced since the kernel stable release v5.15-rc1.
As described in commit d9820ff after switch pgtable_t back to struct
page *, a pointer to "struct page" and appropriate functions are used to
allocate and free a memory page for PTEs, but the pmd_pgtable macro hasn't
changed and returns the direct virtual address from the PMD (PGD) entry.
Than this address used as a parameter in the __pte_free() and as a result
this function couldn't release memory page allocated for PTEs.
Fix this issue by changing the pmd_pgtable macro and returning pointer to
struct page.

Convert Qualcomm SDM845 pin controller bindings to DT schema. Keep
the parsing of pin configuration subnodes consistent with other Qualcomm
schemas (children named with '-state' suffix, their children with
'-pins').
