Define a small SDTL_INIT(maskfn, flagsfn, name) macro and use it to build the
sched_domain_topology_level array. Purely a cleanup; behaviour is unchanged.

Let's move the removal of the page from the balloon list into the single
caller, to remove the dependency on the PG_isolated flag and clarify
locking requirements.
Note that for now, balloon_page_delete() was used on two paths:
(1) Removing a page from the balloon for deflation through
balloon_page_list_dequeue()
(2) Removing an isolated page from the balloon for migration in the
per-driver migration handlers. Isolated pages were already removed from
the balloon list during isolation.
So instead of relying on the flag, we can just distinguish both cases
directly and handle it accordingly in the caller.
We'll shuffle the operations a bit such that they logically make more
sense (e.g., remove from the list before clearing flags).
In balloon migration functions we can now move the balloon_page_finalize()
out of the balloon lock and perform the finalization just before dropping
the balloon reference.
Document that the page lock is currently required when modifying the
movability aspects of a page; hopefully we can soon decouple this from the
page lock.

Only mips and loongarch implemented this API, however what it does was
checking against stack overflow for either len or addr. That's already
done in arch's arch_get_unmapped_area*() functions, even though it may not
be 100% identical checks.
For example, for both of the architectures, there will be a trivial
difference on how stack top was defined. The old code uses STACK_TOP
which may be slightly smaller than TASK_SIZE on either of them, but the
hope is that shouldn't be a problem.
It means the whole API is pretty much obsolete at least now, remove it
completely.

The Liontron H-A133L board features an Ethernet controller with a
JLSemi JL1101 PHY. Its reset pin is tied to the PH12 GPIO.
Note that the reset pin must be handled as a bus-wide reset GPIO in
order to let the MDIO core properly reset it before trying to read
its identification registers. There's no other device on the MDIO bus.
The datasheet of the PHY mentions that the reset signal must be held
for 1 ms to take effect. Make it 2 ms (and the same for post-delay) to
be on the safe side without wasting too much time during boot.

PinePhone Pro
Add the description of the rear/world camera (IMX258) on the PinePhone Pro
to the device dts file.
It receives commands on the I2C Bus 1 at address 0x1a and transmits data
over CSI-MIPI.
The I2C address for IMX258 can be found in the IMX258-0AQH5 Software
Reference Manual, page 24, section 2.3.1: 0b0011010 = 0x1a.
Section 3 indicates the module has 4 pairs of data lines. While 4-lane
mode is nominal, 2-lane mode should also be supported.
The pin muxing info was extracted from the PinePhone Pro schematic v1.0
as well as the RK3399 datasheet revision 1.8.
Table 2-3 in section 2.8 of the RK3399 datasheet contains the mapping
of IO functions for the SoC pins. Page 52 shows GPIO1_A0, page 54 shows
GPIO2_D4.
For I2C power, the PinePhone Pro schematic page 11 quadrants A4 and A5:
RK3399_J.AA8 and RK3399_J.Y8 get power from vcaa1v8_codec, so turn it on
The IMX258 also uses the following regulators, expected by its driver:
- vana (2.8V analog), called AVDD2V8_DVP on P.18 q.C1 and derived from
VCC1V8_S3 on P.13 q.B2
- vdig (1.2V digital core), called DVDD_DVP on P.18 q.C1 and shown on
P.18 q.D3 to be equivalent to VCC1V2_DVP derived from VCC3V3_SYS on
P.13 q.B3. Note that this regulator's voltage is inconsistently
labeled either 1.2V or 1.5V
RK3399_J.AG1 is GPIO4_A1/I2C1_SDA, RK3399_J.Y6 is GPIO4_A2/I2C1_SCL
This is the default pinctrl "i2c1_xfer" for i2c1 from rk3399-base.

The bootloader for RK3588 Tiger currently forces the PMIC reset behavior
(stored in RST_FUN bitfield in register SYS_CFG3 of the PMIC) to 0b1X
which is incorrect for our devices.
It is required to restart the PMU as otherwise the companion
microcontroller cannot detect the PMIC (and by extension the full
product and main SoC) being rebooted which is an issue as that is used
to reset a few things like the PWM beeper and watchdogs.
Let's add the new rockchip,reset-mode property to make sure the PMIC
reset behavior is the expected one.

To make it easier to read the device tree, let's add constants for the
rockchip,reset-mode property values that are currently only applicable
to RK806 PMIC.

Much like the Sige5, the ROCK 4D also has an HDMI port, so is capable of
providing HDMI audio output as well.
Enable the SoC's hdmi_sound card, and also enable the SoC audio
controller (sai6) that feeds into it.
