dd601dbc01 clk: meson: clk-pll: drop hard-coded rates from pll tables
Putting hard-coded rates inside the parameter tables assumes that
the parent is known and will never change. That's a big assumption
we should not make.

We have everything we need to recalculate the output rate using
the parent rate and the rest of the parameters. Let's do so and
drop the rates from the tables.

87173557d2 clk: meson: clk-pll: remove od parameters
Remove od parameters from pll clocks and add post dividers clocks
instead. Some clock, especially the one which feature several ods,
may provide output between those ods. Also, some drivers, such
as the hdmi driver, may require a more detailed control of the
clock dividers, compared to what CCF would perform automatically.

One added benefit of removing ods is that it also greatly reduce the
size of the rate parameter tables.

In the future, we could possibly take the predivider 'n' out of this
driver as well. To do so, we will need to understand the constraints
for the PLL to lock and whether or not it depends on the input clock
rate.

2303a9ca69 clk: meson: clk-pll: drop CLK_GET_RATE_NOCACHE where unnecessary
CLK_GET_RATE_NOCACHE should only be necessary when the registers
controlling the rate of clock may change outside of CCF. On Amlogic,
it should only be the case for the hdmi pll which is directly controlled
by the display driver (WIP to fix this).

The other plls should not require this flag.

e40c7e3cda clk: meson: clk-pll: add enable bit
Add the enable the bit of the pll clocks.
These pll clocks may be disabled but we can't model this as an external
gate since the pll needs to lock when enabled.

Adding this bit allows to drop the poke of the first register of PLL.
This will be useful to model the different components of the pll using
generic clocks elements

ba93cc7da8 USB: serial: ftdi_sio: implement GPIO support for FT-X devices
This patch allows using the CBUS pins of FT-X devices as GPIO in CBUS
bitbanging mode. There is no conflict between the GPIO and VCP
functionality in this mode. Tested on FT230X and FT231X.

As there is no way to request the current CBUS register configuration
from the device, all CBUS pins are set to a known state when the first
GPIO is requested. This allows using libftdi to set the GPIO pins
before loading this module for UART functionality, a behavior that
existing applications might be relying upon (though no specific case
is known to the authors of this patch).

Crash happened because list_del_rcu() was called twice for smp->ltk. This
was possible if unpair_device was called right after ltk was generated
but before keys were distributed.

In this commit smp_cancel_pairing was refactored to cancel pairing if it
is in progress and otherwise just removes keys. Once keys are removed from
rcu list, pointers to smp context's keys are set to NULL to make sure
removed list items are not accessed later.

This commit also adjusts the functionality of mgmt unpair_device() little
bit. Previously pairing was canceled only if pairing was in state that
keys were already generated. With this commit unpair_device() cancels
pairing already in earlier states.

Bug was found by fuzzing kernel SMP implementation using Synopsys
Defensics.

28ef8b49a3 mac80211_hwsim: do not omit multicast announce of first added radio
The allocation of hwsim radio identifiers uses a post-increment from 0,
so the first radio has idx 0. This idx is explicitly excluded from
multicast announcements ever since, but it is unclear why.

Drop that idx check and announce the first radio as well. This makes
userspace happy if it relies on these events.

f1c47eb61d mac80211_hwsim: fix race in radio destruction from netlink notifier
The asynchronous destruction from a work-queue of radios tagged with
destroy-on-close may race with the owning namespace about to exit,
resulting in potential use-after-free of that namespace.

Instead of using a work-queue, move radios about to destroy to a
temporary list, which can be worked on synchronously after releasing
the lock. This should be safe to do from the netlink socket notifier,
as the namespace is guaranteed to not get released.

628980e5c8 mac80211_hwsim: fix locking when iterating radios during ns exit
The cleanup of radios during namespace exit has recently been reworked
to directly delete a radio while temporarily releasing the spinlock,
fixing a race condition between the work-queue execution and namespace
exits. However, the temporary unlock allows unsafe modifications on the
iterated list, resulting in a potential crash when continuing the
iteration of additional radios.

Move radios about to destroy to a temporary list, and clean that up
after releasing the spinlock once iteration is complete.

288cb5d1db ARM: dts: meson8b: odroidc1: add the fixed voltage regulators
There are multiple fixed regulators on the Odroid-C1 board. Add them so
they can be used when we add the devices that need them (SAR ADC needs
the 1.8V IOREF, RTC needs VDD_RTC).
These are:
- P5V0 is the main 5V power input
- VCC3V3 / VDDIO_AO3V3 / VDD3V3: fixed regulator with 3.3V output which
  is supplied by P5V0
- IOREF_1V8 / VCC1V8 / VDD1V8: fixed regulator with 1.8V output which is
  supplied by P5V0
- VDD_RTC: fixed voltage regulator with 0.9V output which is supplied by
  VDDIO_AO3V3
- DDR_VDDC / DDR3_1V5: fixed voltage regulator with 1.5V output which is
  supplied by P5V0
- the existing TF_IO and RFLASH_VDD_EN regulators are supplied by
  VDDIO_AO3V3
- the existing VCCK regulator is supplied by P5V0

This does not add the missing VDDEE regulator (controlled by PWM_D)
because it's not clear yet how to configure the voltage of that
regulator.

524d96083b ARM: dts: meson8b: odroidc1: add the CPU voltage regulator
The CPU voltage regulator is a "Monolithic Power Systems MP2161"
(according to the Odroid-C1+'s schematics). It is driven by PWM_C on
GPIODV_9.

Hardkernel's 3.10 kernel (based on the Amlogic GPL kernel sources)
defines a PWM voltage table with the following values:
- 0.86 volts = PWM register value 0x10f001b
- (more values in 0.1 volt increments)
- 1.14 volts = PWM register value 0x000012a
When using the XTAL (24MHz) as input this translates into a PWM period
of 12218ns with 0.86V using a duty cycle of 91% and 1.14V using a duty
cycle of 0%.

bbedc1f1d9 ARM: dts: meson8b: Add support for the Endless Mini (EC-100)
The Endless Mini (EC-100) is a grapefruit-sized computer based on the
Amlogic Meson8b (S805) SoC which comes in two variants.

Both variants have in common:
- Amlogic Meson8b (S805) SoC
- two USB 2.0 ports on the rear, one one the front (connected to the SoC
  through an internal hub)
- 3.5mm Stereo out and MIC combo port
- HDMI and CVBS output
- 5V power supply (rated at 3A / 15W)
- an internal embedded micro-controller (called "EC") which implements a
  "breathing" effect for the LED and allows shutting down (powering off)
  the whole device
- 10/100 Mbit/s Ethernet using an IC Plus IP101A/G PHY (note: the website
  incorrectly lists a Gigabit Ethernet port)
- the CPU voltage is regulated using a PWM regulator. The GPL sources of
  the EC-100 are using a PWM value of 0x1c0000 for 0.86V and a PWM value
  of 0x00001c for 1.14V. When using the XTAL (24MHz) as input this
  translates into a PWM period of 1148ns with 0.86V using a duty cycle of
  100% and 1.14V using a duty cycle of 0%.

The main differences are:
- the main indicator for the variant is the RAM size: the "cheaper"
  variant has 1 GB of RAM, while the more expensive one comes with 2GB
- the storage size differs: 24 GB vs 32 GB
- the "1 GB RAM" variant has Ethernet connectivity only, while the "2 GB"
  variant has a Realtek RTL8723BS SDIO chip which adds 802.11b/g/n wifi
  and Bluetooth 4.0 support

3194cdb711 KVM: s390: introduce and use KVM_REQ_VSIE_RESTART
When we change the crycb (or execution controls), we also have to make sure
that the vSIE shadow datastructures properly consider the changed
values before rerunning the vSIE. We can achieve that by simply using a
VCPU request now.

This has to be a synchronous request (== handled before entering the
(v)SIE again).

The request will make sure that the vSIE handler is left, and that the
request will be processed (NOP), therefore forcing a reload of all
vSIE data (including rebuilding the crycb) when re-entering the vSIE
interception handler the next time.
