ARM: ep93xx: add regmap aux_dev
The following driver's should be instantiated by ep93xx syscon driver:
- reboot
- pinctrl
- clock
They all require access to DEVCFG register with a shared lock held, to
avoid conflict writing to swlocked parts of DEVCFG.
Provide common resources such as base, regmap and spinlock via auxiliary
bus framework.

gpio: ep93xx: split device in multiple
Prepare ep93xx SOC gpio to convert into device tree driver:
- dropped banks and legacy defines
- split AB IRQ and make it shared
We are relying on IRQ number information A, B ports have single shared
IRQ, while F port have dedicated IRQ for each line.
Also we had to split single ep93xx platform_device into multiple, one
for each port, without this we can't do a full working transition from
legacy platform code into device tree capable. All GPIO_LOOKUP were
change to match new chip namings.

ep93xx device tree conversion
The goal is to recieve ACKs for all patches in series to merge it via Arnd branch.
Unfortunately, CLK subsystem suddenly went silent on clk portion of series V2 reroll,
tried to ping them for about a month but no luck.
Link: https://lore.kernel.org/r/20240408-ep93xx-clk-v2-1-adcd68c13753@maquefel.me
Some changes since last version (v9) - see "Changes in v10", mostly
cosmetic.
Following patches require attention from Stephen Boyd or clk subsystem:

KVM: x86: Drop support for hand tuning APIC timer advancement from userspace
Remove support for specifying a static local APIC timer advancement value,
and instead present a read-only boolean parameter to let userspace enable
or disable KVM's dynamic APIC timer advancement. Realistically, it's all
but impossible for userspace to specify an advancement that is more
precise than what KVM's adaptive tuning can provide. E.g. a static value
needs to be tuned for the exact hardware and kernel, and if KVM is using
hrtimers, likely requires additional tuning for the exact configuration of
the entire system.
Dropping support for a userspace provided value also fixes several flaws
in the interface. E.g. KVM interprets a negative value other than -1 as a
large advancement, toggling between a negative and positive value yields
unpredictable behavior as vCPUs will switch from dynamic to static
advancement, changing the advancement in the middle of VM creation can
result in different values for vCPUs within a VM, etc. Those flaws are
mostly fixable, but there's almost no justification for taking on yet more
complexity (it's minimal complexity, but still non-zero).
The only arguments against using KVM's adaptive tuning is if a setup needs
a higher maximum, or if the adjustments are too reactive, but those are
arguments for letting userspace control the absolute max advancement and
the granularity of each adjustment, e.g. similar to how KVM provides knobs
for halt polling.

KVM: SEV-ES: Delegate LBR virtualization to the processor
As documented in APM[1], LBR Virtualization must be enabled for SEV-ES
guests. Although KVM currently enforces LBRV for SEV-ES guests, there
are multiple issues with it:
o MSR_IA32_DEBUGCTLMSR is still intercepted. Since MSR_IA32_DEBUGCTLMSR
interception is used to dynamically toggle LBRV for performance reasons,
this can be fatal for SEV-ES guests. For ex SEV-ES guest on Zen3:
[guest ~]# wrmsr 0x1d9 0x4

EAX=
00000004 EBX=
00000000 ECX=
000001d9 EDX=
00000000
Fix this by never intercepting MSR_IA32_DEBUGCTLMSR for SEV-ES guests.
No additional save/restore logic is required since MSR_IA32_DEBUGCTLMSR
is of swap type A.
o KVM will disable LBRV if userspace sets MSR_IA32_DEBUGCTLMSR before the
VMSA is encrypted. Fix this by moving LBRV enablement code post VMSA
encryption.

cpufreq: intel_pstate: Fix unchecked HWP MSR access
Fix unchecked MSR access error for processors with no HWP support. On
such processors, maximum frequency can be changed by the system firmware
using ACPI event ACPI_PROCESSOR_NOTIFY_HIGEST_PERF_CHANGED. This results
in accessing HWP MSR 0x771.
Call Trace:
<TASK>

HWP MSR 0x771 can be only read on a CPU which supports HWP and enabled.
Hence intel_pstate_get_hwp_cap() can only be called when hwp_active is
true.

LoongArch: Fix GMAC's phy-mode definitions in dts
The GMAC of Loongson chips cannot insert the correct 1.5-2ns delay. So
we need the PHY to insert internal delays for both transmit and receive
data lines from/to the PHY device. Fix this by changing the "phy-mode"
from "rgmii" to "rgmii-id" in dts.

LoongArch: Override higher address bits in JUMP_VIRT_ADDR
In JUMP_VIRT_ADDR we are performing an or calculation on address value

This will only work if we are currently running from direct 1:1 mapping

we should not rely on such assumption.
Fix by overriding higher bits in address comes from pcaddi, so we can
get rid of or operator.

Currently kernel entry in head.S is in DMW address range, firmware is
instructed to jump to this address after loading the kernel image.
However kernel should not make any assumption on firmware's DMW

direct translation region.
Fix by converting entry address to physical and amend entry calculation

potential build errors in future, and give a signal to indicate the code

x86/topology/intel: Unlock CPUID before evaluating anything
Intel CPUs have a MSR bit to limit CPUID enumeration to leaf two. If
this bit is set by the BIOS then CPUID evaluation including topology
enumeration does not work correctly as the evaluation code does not try
to analyze any leaf greater than two.
This went unnoticed before because the original topology code just
repeated evaluation several times and managed to overwrite the initial
limited information with the correct one later. The new evaluation code
does it once and therefore ends up with the limited and wrong
information.
Cure this by unlocking CPUID right before evaluating anything which
depends on the maximum CPUID leaf being greater than two instead of
rereading stuff after unlock.

-The port is not defined as external in the per port PxCMD register, and

Partial and Slumber LPM states can either be initiated by HIPM or DIPM.
For HIPM (host initiated power management) to get enabled, both the AHCI

device requests to enter LPM states which the HBA does not support.
The problem is that Apacer AS340 drives do not handle low power modes

RISC-V: KVM: Fix incorrect reg_subtype labels in kvm_riscv_vcpu_set_reg_isa_ext function
In the function kvm_riscv_vcpu_set_reg_isa_ext, the original code
used incorrect reg_subtype labels KVM_REG_RISCV_SBI_MULTI_EN/DIS.
These have been corrected to KVM_REG_RISCV_ISA_MULTI_EN/DIS respectively.
Although they are numerically equivalent, the actual processing
will not result in errors, but it may lead to ambiguous code semantics.

RISC-V: KVM: No need to use mask when hart-index-bit is 0
When the maximum hart number within groups is 1, hart-index-bit is set to
0. Consequently, there is no need to restore the hart ID from IMSIC
addresses and hart-index-bit settings. Currently, QEMU and kvmtool do not
pass correct hart-index-bit values when the maximum hart number is a
power of 2, thereby avoiding this issue. Corresponding patches for QEMU
and kvmtool will also be dispatched.

blk-throttle: Fix incorrect display of io.max
Commit
bf20ab538c81 ("blk-throttle: remove CONFIG_BLK_DEV_THROTTLING_LOW")
attempts to revert the code change introduced by commit
cd5ab1b0fcb4
("blk-throttle: add .low interface"). However, it leaves behind the
bps_conf[] and iops_conf[] fields in the throtl_grp structure which
aren't set anywhere in the new blk-throttle.c code but are still being
used by tg_prfill_limit() to display the limits in io.max. Now io.max
always displays the following values if a block queue is used:
<m>:<n> rbps=0 wbps=0 riops=0 wiops=0
Fix this problem by removing bps_conf[] and iops_conf[] and use bps[]
and iops[] instead to complete the revert.

of: property: Fix fw_devlink handling of interrupt-map
Commit
d976c6f4b32c ("of: property: Add fw_devlink support for
interrupt-map property") tried to do what it says on the tin,
but failed on a couple of points:
- it confuses bytes and cells. Not a huge deal, except when it
comes to pointer arithmetic
- it doesn't really handle anything but interrupt-maps that have
their parent #address-cells set to 0
The combinations of the two leads to some serious fun on my M1
box, with plenty of WARN-ON() firing all over the shop, and
amusing values being generated for interrupt specifiers.
Having 2 versions of parsing code for "interrupt-map" was a bad
idea. Now that the common parsing parts have been refactored
into of_irq_parse_imap_parent(), rework the code here to use it
instead and fix the pointer arithmetic.
Note that the dependency will be a bit different than the original code
when the interrupt-map points to another interrupt-map. In this case,
the original code would resolve to the final interrupt controller. Now
the dependency is the parent interrupt-map (which itself should have a
dependency to the parent). It is possible that a node with an
interrupt-map has no driver.

Factor out the parsing of interrupt-map interrupt parent phandle and its

can be used in other parsing scenarios (e.g. fw_devlink).
There was a refcount leak on non-matching entries when iterating thru
