e53237aa53 arm: apple: Add initial Apple M2 support
Apple's M2 SoC very similar to the M1 and can use the same memory map.
The keyboard/trackpad on the MacBook Pro (13-inch, M2, 2022) uses
"dockchannel" as transport instead of SPI and needs a new driver.
USB, NVMe, uart, framebuffer and watchdog are working with the existing
drivers.

538f6643b0 Merge commit '90ba25b7cb78bd85c6af0b6429226c6616dedefa' of https://source.denx.de/u-boot/custodians/u-boot-nand-flash
In preparation of re-sync of mtd stack, we opt to move the current stack
slowly in order to have a more easy sync and test. We would like to
prepare uboot to support no-jedec and no-onfi compliant nand so we need
to clean up a bit the code we have now and upstream some of the support.
In this series we expect no functional change

Tested on:
 - imx6ull Micron   MT29F2G08ABAGAH4
 - imx8mn  Macronix MX30LF4G18AC

90ba25b7cb mtd: decommission the NAND museum
Upstream linux commit f7025a43a9da26.

The MTD subsystem has its own small museum of ancient NANDs in a form of
the CONFIG_MTD_NAND_MUSEUM_IDS configuration option. The museum contains
stone age NANDs with 256 bytes pages, as well as iron age NANDs with 512
bytes per page and up to 8MiB page size.

It is with great sorrow that I inform you that the museum is being
decommissioned. The MTD subsystem is out of budget for Kconfig options and
already has too many of them, and there is a general kernel trend to
simplify the configuration menu.

We remove the stone age exhibits along with closing the museum

REMARK Don't apply this part from upstream:

Some of the iron age ones are transferred to the regular NAND depot.
Namely, only those which have unique device IDs are transferred, and the
ones which have conflicting device IDs are removed.

meaning changes with the NAND generation.

Providing this vendor specific initialization step will allow us to get

cases added over the time in the generic NAND ID decoding logic.

1fc45d6483 watchdog: add pulse support to gpio watchdog driver
A common external watchdog circuit is kept alive by triggering a short
pulse on the reset pin. This patch adds support for this use case, while
making the algorithm configurable in the devicetree.

The "linux,wdt-gpio" driver being modified is based off the equivalent
driver in the Linux kernel, which provides support for this algorithm.
This patch brings parity to this driver, and is kept aligned with
the functionality and devicetree configuration in the kernel.

It should be noted that this adds a required property named 'hw_algo'
to the devicetree binding, following suit with the kernel. I'm happy to
make this backward-compatible if preferred.

b4f210563e ubifs: Fix ubifs_assert_cmt_locked()
U-Boot does not implement down_write_trylock() and its stub always returns
true that lock was acquired. Therefore ubifs_assert_cmt_locked() assert
currently always fails.

Fix this issue by redefining ubifs_assert_cmt_locked() to just empty stub
as there is nothing to assert.

To quote Andre:

One prominent feature is the restructering of the clock driver, which
allows to end up with one actual driver for all variants, although we
still only compile in support for one SoC.
Also contained are some initial SPI fixes, which should fix some
problems, and enable SPI flash support for the F1C100s SoC. Those
patches revealed more problems, I will queue fixes later on, but for
now it should at least still work.
Apart from some smaller fixes (for instance for NAND operation), there
is also preparation for the upcoming Allwinner D1 support, in form of
the USB PHY driver. There are more driver support patches to come.

The gitlab CI completed successfully, including the build test for all
160 sunxi boards. I also boot tested on a few boards, but didn't have
time for more elaborate tests this time.

49f3a42edf i2c: avoid dynamic stack use in dm_i2c_write
The size of the dynamic stack allocation here is bounded by the if()
statement. However, just allocating the maximum size up-front and
doing malloc() if necessary avoids code duplication (the
i2c_setup_offset() until the invocation of ->xfer), and generates much
better (smaller) code:

bloat-o-meter drivers/i2c/i2c-uclass.o.{0,1}
add/remove: 0/0 grow/shrink: 0/1 up/down: 0/-144 (-144)
Function                                     old     new   delta
dm_i2c_write                                 552     408    -144
Total: Before=3828, After=3684, chg -3.76%

It also makes static analysis of maximum stack usage (using the .su
files that are automatically generated during build) easier if there
are no lines saying "dynamic".

[This is not entirely equivalent to the existing code; this now uses
the stack for len <= 64 rather than len <= 63, but that seems like a
more natural limit.]

6ac25538d8 i2c: ast_i2c: Remove SCL direct drive mode
SCL direct drive mode prevents communication with devices that
do clock stretching, so disable. The Linux driver doesn't use
this mode, and the engine can handle clock stretching.

25ba5be1c2 phy: sun4i-usb: Add D1 variant
D1 has a register layout like A100 and H616, with the moved SIDDQ bit.
Unlike H616 it does not have any dependencies between PHY instances.

b33ee49ac1 phy: sun4i-usb: Rework HCI PHY (aka "pmu_unk1") handling
As Icenowy pointed out, newer manuals (starting with H6) actually
document the register block at offset 0x800 as "HCI controller and PHY
interface", also describe the bits in our "PMU_UNK1" register.
Let's put proper names to those "unknown" variables and symbols.

While we are at it, generalise the existing code by allowing a bitmap
of bits to clear and set, to cover newer SoCs: The A100 and H616 use a
different bit for the SIDDQ control.
