Variscite has updated the Ethernet PHY on the VAR-SOM-MX93 from the
ADIN1300BCPZ to the MaxLinear MXL86110, as documented in the
August 2023 revision changelog.
Link: https://variwiki.com/index.php?title=VAR-SOM-MX93_rev_changelog
Update the device tree accordingly:
- Drop the regulator node used to power the previously PHY.
- Add support for the reset line using GPIO1_IO07 with proper timings.
- Configure the PHY LEDs via the LED subsystem under /sys/class/leds/,
leveraging the support implemented in the mxl86110 PHY driver
(drivers/net/phy/mxl-86110.c).
Two LEDs are defined to match the LED configuration on the Variscite
VAR-SOM Carrier Boards:
* LED@0: Yellow, netdev trigger.
* LED@1: Green, netdev trigger.
- Adjust the RGMII clock pad control settings to match the updated PHY
requirements.
These changes ensure proper PHY initialization and LED status indication
for the new MaxLinear MXL86110, improving board compatibility with the
latest hardware revision.

Move configuration for ADC voltage reference from board DTS to a SoM
include file. The SoC ADC reference voltage is connected to a "VDDA_1V8"
voltage node and supplied by the PMIC's BUCK5 regulator. The reference
voltage is thus defined by the SoM and cannot be changed by the carrier
board design and as such belongs into the SoM include file.
Moreover, with this in place, customers designing own carrier boards can
simply include imx93-phycore-som.dtsi and enable adc1 in their own DTS
without the need to define dummy ADC vref regulator themselves anymore.

When converting a region via contpte_convert() to use mTHP, we have two
different goals. We have to mark each entry as contiguous, and we would
like to smear the dirty and young (access) bits across all entries in
the contiguous block. Currently, we do this by first accumulating the
dirty and young bits in the block, using an atomic
__ptep_get_and_clear() and the relevant pte_{dirty,young}() calls,
performing a tlbi, and finally smearing the correct bits across the
block using __set_ptes().
This approach works fine for BBM level 0, but with support for BBM level
2 we are allowed to reorder the tlbi to after setting the pagetable
entries. We expect the time cost of a tlbi to be much greater than the
cost of clearing and resetting the PTEs. As such, this reordering of the
tlbi outside the window where our PTEs are invalid greatly reduces the
duration the PTE are visibly invalid for other threads. This reduces the
likelyhood of a concurrent page walk finding an invalid PTE, reducing
the likelyhood of a fault in other threads, and improving performance
(more so when there are more threads).
Because we support via allowlist only bbml2 implementations that never
raise conflict aborts and instead invalidate the tlb entries
automatically in hardware, we can avoid the final flush altogether.
However, avoiding the intermediate tlbi+dsb must be carefully considered
to ensure that we remain both correct and performant. We document our
reasoning and the expected interactions further in the contpte_convert()
source. To do so we rely on the aarch64 spec (DDI 0487L.a D8.7.1.1)
requirements RNGLXZ and RJQQTC to provide guarantees that the elision is
correct.

The Break-Before-Make cpu feature supports multiple levels (levels 0-2),
and this commit adds a dedicated BBML2 cpufeature to test against
support for.
To support BBML2 in as wide a range of contexts as we can, we want not
only the architectural guarantees that BBML2 makes, but additionally
want BBML2 to not create TLB conflict aborts. Not causing aborts avoids
us having to prove that no recursive faults can be induced in any path
that uses BBML2, allowing its use for arbitrary kernel mappings.
This feature builds on the previous ARM64_CPUCAP_EARLY_LOCAL_CPU_FEATURE,
as all early cpus must support BBML2 for us to enable it (and any later
cpus must also support it to be onlined).
Not onlining late cpus that do not support BBML2 is unavoidable, as we
might currently be using BBML2 semantics for kernel memory regions. This
could cause faults in the late cpus, and would be difficult to unwind,
so let us avoid the case altogether.

For system-wide capabilities, the kernel has the SCOPE_SYSTEM type. Such
capabilities are checked once the SMP boot has completed using the
sanitised ID registers. However, there is a need for a new capability
type similar in scope to the system one but with checking performed
locally on each CPU during boot (e.g. based on MIDR_EL1 which is not a
sanitised register).
Introduce ARM64_CPUCAP_MATCH_ALL_EARLY_CPUS which, together with
ARM64_CPUCAP_SCOPE_LOCAL_CPU, ensures that such capability is enabled
only if all early CPUs have it. For ease of use, define
ARM64_CPUCAP_EARLY_LOCAL_CPU_FEATURE which combines SCOPE_LOCAL_CPU,
PERMITTED_FOR_LATE_CPUS and MATCH_ALL_EARLY_CPUS.

Move the arm64-optimized CRC code from arch/arm64/lib/crc* into its new
location in lib/crc/arm64/, and wire it up in the new way. This new way
of organizing the CRC code eliminates the need to artificially split the
code for each CRC variant into separate arch and generic modules,
enabling better inlining and dead code elimination. For more details,
see "lib/crc: Prepare for arch-optimized code in subdirs of lib/crc/".

Move the contents of arch/arm64/lib/crypto/ into lib/crypto/arm64/.
The new code organization makes a lot more sense for how this code
actually works and is developed. In particular, it makes it possible to
build each algorithm as a single module, with better inlining and dead
code elimination. For a more detailed explanation, see the patchset
which did this for the CRC library code:
https://lore.kernel.org/r/20250607200454.73587-1-ebiggers@kernel.org/.
Also see the patchset which did this for SHA-512:
https://lore.kernel.org/linux-crypto/20250616014019.415791-1-ebiggers@kernel.org/
This is just a preparatory commit, which does the move to get the files
into their new location but keeps them building the same way as before.
Later commits will make the actual improvements to the way the
arch-optimized code is integrated for each algorithm.
Add a gitignore entry for the removed directory arch/arm64/lib/crypto/
so that people don't accidentally commit leftover generated files.

Instead of exposing the arm64-optimized SHA-512 code via arm64-specific
crypto_shash algorithms, instead just implement the sha512_blocks()
library function. This is much simpler, it makes the SHA-512 (and
SHA-384) library functions be arm64-optimized, and it fixes the
longstanding issue where the arm64-optimized SHA-512 code was disabled
by default. SHA-512 still remains available through crypto_shash, but
individual architectures no longer need to handle it.
To match sha512_blocks(), change the type of the nblocks parameter of
the assembly functions from int or 'unsigned int' to size_t. Update the
ARMv8 CE assembly function accordingly. The scalar assembly function
actually already treated it as size_t.

Since commit c871a311edf0 ("phy: rockchip: samsung-hdptx: Setup TMDS
char rate via phy_configure_opts_hdmi"), the workaround of passing the
rate from DW HDMI QP bridge driver via phy_set_bus_width() became
partially broken, as it cannot reliably handle mode switches anymore.
Attempting to fix this up at PHY level would not only introduce
additional hacks, but it would also fail to adequately resolve the
display issues that are a consequence of the system CRU limitations.
Instead, proceed with the solution already implemented for RK3588: make
use of the HDMI PHY PLL as a better suited DCLK source for VOP2. This
will not only address the aforementioned problem, but it should also
facilitate the proper operation of display modes up to 4K@60Hz.
It's worth noting that anything above 4K@30Hz still requires high TMDS
clock ratio and scrambling support, which hasn't been mainlined yet.

Hardware CS has a very slow rise time of about 6us,
causing transmission errors when CS does not reach
high between transaction.
It looks like it's not driven actively when transitioning
from low to high but switched to input, so only the CPU
pull-up pulls it high, slowly. Transitions from high to low
are fast. On the oscilloscope, CS looks like an irregular sawtooth
pattern like this:
_____
^ / |
^ /| / |
/| / | / |
/ | / | / |
___/ |___/ |_____/ |___
With cs-gpios we have a CS rise time of about 20ns, as it should be,
and CS looks rectangular.
This fixes the data errors when running a flashcp loop against a
m25p40 spi flash.
With the Rockchip 6.1 kernel we see the same slow rise time, but
for some reason CS is always high for long enough to reach a solid
high.
The RK3399 and RK3588 SoCs use the same SPI driver, so we also
checked our "Puma" (RK3399) and "Tiger" (RK3588) boards.
They do not have this problem. Hardware CS rise time is good.

gs101 (Google Pixel 6 and Pixel 6 Pro) supports cold- and warm-reboot.
Cold-reset is useful because it is more secure, e.g. wiping all RAM
contents, while the warm-reboot allows RAM contents to be retained
across the reboot, e.g. to collect potential crash information.
Add the required DT changes to switch to the gs101-specific reboot
method, which knows how to issue either reset as requested by the OS.
The PMIC plays a role in this as well, so mark it as
'system-power-controller', which in this case ensures that the device
will wake up again after a cold-reboot, ensuring the full power-cycle
is successful.

contains the following functional blocks:
* common / speedy interface
* regulators
* 3 clock outputs
* RTC
* power meters
* GPIO interfaces
This change enables the PMIC itself and the RTC. We're still working on
the remaining parts or waiting for bindings to be merged, hence only a
small subset of the functional is being enabled.
The regulators fall into the same category (still being finalised), but
since the binding requires a 'regulators' node, an empty node is being
added to avoid validation errors at this stage.

On gs101, the boot mode is stored both in a syscon register, and in
nvmem.
Add the dm-verity-device-corrupted reboot mode to the syscon-reboot-
based boot mode as well, as both (nvmem & syscon) modes should be in
sync.

On Pixel 6 (and Pro), a MAX77759 companion PMIC for USB Type-C
applications is used, which contains four functional blocks (at
distinct I2C addresses):
* top (including GPIO & NVMEM)
* charger
* fuel gauge
* TCPCi
This change adds the PMIC and the subnodes for the GPIO expander and
NVMEM, and defines the NVMEM layout.
The NVMEM layout is declared such that it matches downstream's
open-coded configuration [1].
Note:
The pinctrl nodes are kept sorted by the 'samsung,pins' property rather
than node name, as I think that makes it easier to look at and to add
new nodes unambiguously in the future. Its label is prefixed with 'if'
(for interface), because there are three PMICs in total in use on
Pixel 6 (Pro).

Enable the Maxim max77759 as this is used by the gs101-oriole and
gs101-raven (Google Pixel 6 and Pixel 6 Pro) boards,
The child devices' defaults are based on this MFD driver's state, so
this commit enables those implicitly as well.
