MP8867 is an I2C-controlled adjustable voltage regulator made by
Monolithic Power Systems. The difference between MP8867 and MP8869
are:
1.If V_BOOT, the vref of MP8869 is fixed at 600mv while vref of
MP8867 is determined by the I2C control.
2.For MP8867, when setting voltage, if the step is within 5, we
need to manually set the GO BIT to 0.

The MP8869 from Monolithic Power Systems is a single output DC/DC
converter. The voltage can be controlled via I2C.

This is happening because we have a pending doorbell that requires
retrigger. As SW retriggering is done in a tasklet, we trigger the
circular dependency above.
The easy cop-out is to provide a retrigger callback that doesn't
require acquiring any extra lock.

The GICv3 ITS driver assumes that once it has latched on a page size for
a given BASER register, it can use the same page size as the maximum
page size for all subsequent BASER registers.
Although it worked so far, nothing in the architecture guarantees this,
and Nianyao Tang hit this problem on some undisclosed implementation.
Let's bite the bullet and probe the the supported page size on all BASER
registers before starting to populate the tables. This simplifies the
setup a bit, at the expense of a few additional MMIO accesses.

Per the spec, the BCM2835's IRQs are all disabled when coming out of
power-on reset. Its IRQ driver assumes that's still the case when the
kernel boots and does not perform any initialization of the registers.
However the Raspberry Pi Foundation's bootloader leaves the USB
interrupt enabled when handing over control to the kernel.
Quiesce IRQs and the FIQ if they were left enabled and log a message to
let users know that they should update the bootloader once a fixed
version is released.
If the USB interrupt is not quiesced and the USB driver later on claims
the FIQ (as it does on the Raspberry Pi Foundation's downstream kernel),
interrupt latency for all other peripherals increases and occasional
lockups occur. That's because both the FIQ and the normal USB interrupt
fire simultaneously:
On a multicore Raspberry Pi, if normal interrupts are routed to CPU 0
and the FIQ to CPU 1 (hardcoded in the Foundation's kernel), then a USB
interrupt causes CPU 0 to spin in bcm2836_chained_handle_irq() until the
FIQ on CPU 1 has cleared it. Other peripherals' interrupts are starved
as long. I've seen CPU 0 blocked for up to 2.9 msec. eMMC throughput
on a Compute Module 3 irregularly dips to 23.0 MB/s without this commit
but remains relatively constant at 23.5 MB/s with this commit.
The lockups occur when CPU 0 receives a USB interrupt while holding a
lock which CPU 1 is trying to acquire while the FIQ is temporarily
disabled on CPU 1. At best users get RCU CPU stall warnings, but most
of the time the system just freezes.

there can be multiple PLICs present on a two socket systems in RISC-V.
Modify the driver so that each PLIC handler can have a information

Currently, PLIC threshold is only initialized once in the beginning.
However, threshold can be set to disabled if a CPU is marked offline with
CPU hotplug feature. This will not allow to change the irq affinity to a
CPU that just came online.
Add PLIC specific CPU hotplug callbacks and enable the threshold when a CPU
comes online. Take this opportunity to move the external interrupt enable
code from trap init to PLIC driver as well. On cpu offline path, the driver
performs the exact opposite operations i.e. disable the interrupt and
the threshold.

This is done in order to remove the confusion that arises at some places
in the code where local variables or arguments shadow the global variable.
It is already visible that some places are a bit awkward and iterate over
the global variable, for the sole reason that they used to rely on it being
named "fdc" in order to get the correct address when using FD_DOR. These
ones are easy to spot by searching for "for (current_fdc...".
Some more cleanup is definitely possible. For example
"fdc_state[current_fdc].somefield" is used all over the code and would
probably be better with "fdc_state->somefield" with fdc_state being set
when current_fdc is assigned. This would require to pass the pointer to
the current state instead of the current_fdc to the I/O functions.

FDC registers FD_STATUS, FD_DATA, FD_DOR, FD_DIR and FD_DCR used to be
defined relative to FD_IOPORT, which is the FDC's base address, itself
a macro depending on the "fdc" local or global variable.
This patch changes this so that the register macros above now only
reference the address offset, and that the FDC's address is explicitly
passed in each call to fd_inb() and fd_outb(), thus removing the macro.
With this change there is no more implicit usage of the local/global
"fdc" variable.
One place in the ARM code used to check if the port was equal to FD_DOR,
this was changed to testing the register by applying a mask to the port,
as was already done in the sparc code.
There are still occurrences of fd_inb() and fd_outb() in the PARISC
code and these ones remain unaffected since they already used to work
with a base address and a register offset.
The sparc, m68k and parisc code could now be slightly cleaned up to
benefit from the macro definitions above instead of the equivalent
hard-coded values.

These two functions replace fd_inb() and fd_outb() in that they take

dm timer ops set_load() api allows to configure the load value and to
set the auto reload feature. But auto reload feature is independent of
load value and should be part of configuring pwm. This way pwm can be
disabled by disabling auto reload feature using set_pwm() so that the
current pwm cycle will be completed. Else pwm disabling causes the
cycle to be stopped abruptly.

Write to trigger register(OMAP_TIMER_TRIGGER_REG) will load the value
in Load register(OMAP_TIMER_LOAD_REG) into Counter register
(OMAP_TIMER_COUNTER_REG).
omap_dm_timer_set_load() writes into trigger register every time load
register is updated. When timer is configured in pwm mode, this causes
disruption in current pwm cycle, which is not expected especially when
pwm is used as PPS signal for synchronized PTP clocks. So do not write
into trigger register on updating the period.

and restore
omap_dm_timer_enable() restores the entire context(including counter)
based on 2 conditions:
- If get_context_loss_count is populated and context is lost.
- If get_context_loss_count is not populated update unconditionally.
Case2 has a side effect of updating the counter register even though
context is not lost. When timer is configured in pwm mode, this is
causing undesired behaviour in the pwm period.
Instead of using get_context_loss_count call back, implement cpu_pm
notifier with context save and restore support. And delete the
get_context_loss_count callback all together.

Let's add runtime_suspend and resume functions and atomic enabled
flag. This way we can use these when converting to use cpuidle
for saving and restoring device context.
And we need to maintain the driver state in the driver as documented
in "9. Autosuspend, or automatically-delayed suspends" in the
Documentation/power/runtime_pm.rst document related to using driver
private lock and races with runtime_suspend().

Netlink support of extended packet number cipher suites,
allows adding and updating XPN macsec interfaces.
Added support in:
* Creating interfaces with GCM-AES-XPN-128 and GCM-AES-XPN-256 suites.
* Setting and getting 64bit packet numbers with of SAs.
* Setting (only on SA creation) and getting ssci of SAs.
* Setting salt when installing a SAK.
Added 2 cipher suite identifiers according to 802.1AE-2018 table 14-1:
* MACSEC_CIPHER_ID_GCM_AES_XPN_128
* MACSEC_CIPHER_ID_GCM_AES_XPN_256
In addition, added 2 new netlink attribute types:
* MACSEC_SA_ATTR_SSCI
* MACSEC_SA_ATTR_SALT
Depends on: macsec: Support XPN frame handling - IEEE 802.1AEbw.

Support extended packet number cipher suites (802.1AEbw) frames handling.
This does not include the needed netlink patches.
* Added xpn boolean field to `struct macsec_secy`.
* Added ssci field to `struct_macsec_tx_sa` (802.1AE figure 10-5).
* Added ssci field to `struct_macsec_rx_sa` (802.1AE figure 10-5).
* Added salt field to `struct macsec_key` (802.1AE 10.7 NOTE 1).
* Created pn_t type for easy access to lower and upper halves.
* Created salt_t type for easy access to the "ssci" and "pn" parts.
* Created `macsec_fill_iv_xpn` function to create IV in XPN mode.
* Support in PN recovery and preliminary replay check in XPN mode.
In addition, according to IEEE 802.1AEbw figure 10-5, the PN of incoming
frame can be 0 when XPN cipher suite is used, so fixed the function
`macsec_validate_skb` to fail on PN=0 only if XPN is off.

drivers/usb/gadget/legacy/Kconfig creates a 'choice' inside another
'choice'.
The outer choice: line 17 "USB Gadget precomposed configurations"
The inner choice: line 484 "EHCI Debug Device mode"
I wondered why the whole legacy gadget drivers reside in such a big
choice block.
This dates back to 2003, "[PATCH] USB: fix for multiple definition of
`usb_gadget_get_string'". [1]
At that time, the global function, usb_gadget_get_string(), was linked
into multiple drivers. That was why only one driver was able to become
built-in at the same time.
Later, commit a84d9e5361bc ("usb: gadget: start with libcomposite")
moved usb_gadget_get_string() to a separate module, libcomposite.ko
instead of including usbstring.c from multiple modules.
More and more refactoring was done, and after commit 1bcce939478f
("usb: gadget: multi: convert to new interface of f_mass_storage"),
you can link multiple gadget drivers into vmlinux without causing
multiple definition error.
This is the only user of the nested choice structure ever. Removing
this mess will make some Kconfig cleanups possible.

Lots of changes on dwc3 this time, most of them from Thinh fixing a
bunch of really old mishaps on the driver.
DWC2 got support for STM32MP15 and a couple RockChip SoCs while DWC3
learned about Amlogic A1 family.
Apart from these, we have a few spelling fixes and other minor
non-critical fixes all over the place.
