rtc: rx8025: revise single register write to use offset
Writing of individual registers was not functioning
correctly as a 0 'offset' byte under DM-managed
I2C was being appended in front of register we
wanted to access.
The RX8025/RX8035 does not like having it's time registers
set byte-by-byte in separate I2C transactions.
From the note at the top of the file, it appears
target-dependent workarounds have been used in the
past for this.
Resolve this by setting the time registers in a single
I2C transaction.
As part of this, also ensure the '24/12' flag in the RTC
is reset before writing the date (instead of after), otherwise
the RX8035 will clear the seconds and minutes registers.
Tested on Traverse Ten64 (NXP LS1088A) with RX8035.

tools: kwboot: Support higher baudrates when booting via UART
Add support for uploading the boot image (the data part only) at higher
baudrate than the standard one.
The kwboot utility already has -B option, but choosing other baudrate
than the standard one (115200 Bd) can only work for debug mode, not for
booting the device. The BootROM for kwboot supported platforms (Orion,
Kirkwood, Dove, Discovery, AXP, A37x, A38x, A39x) cannot change the
baudrate when uploading boot image via the Xmodem protocol, nor can it
be configured via strapping pins.
So instead we add this support by injecting baudrate changing code into
the kwbimage v1 header as a new optional binary extension. This code is
executed by BootROM after it receives the whole header. The code sends
the magic string "$baudratechange\0" just before changing the baudrate
to let kwboot know that it should also change it. This is because the
injected code is run as the last binary extension, and we do not want
to loose possible output from other possible binary extensions that
came before it (in most cases this is U-Boot SPL).
We also inject the code before the payload (the data part of the image),
to change the baudrate back to the standard value, in case the payload
does not reset UART.
This change improves boot time via UART significantly (depending on the
chosen baudrate), which is very useful when debugging.

During the migration to a single DTSI for the CP110-s specific pinctrl

Namely, CP0 eMMC/SDIO support depends on the mvebu-pinctrl driver setting

the eMMC/SDIO PHY to the controller and not use it as a MPP pin multiplexor.
So, the mvebu-pinctrl driver check specifically for the

Issue is that compatibles in the 8040 DTSI were set to "marvell,8k-cpm-pinctrl"
for CP0 and "marvell,8k-cps-pinctrl" for the CP1.
This is obviously incorrect as the pinctrl driver does not know about these.

imx: imx7d-sdb: fix ethernet, sync .dts with linux
Commit 0d52bab46 (mx7dsabre: Enable DM_ETH) changed these flags from 0
(aka GPIO_ACTIVE_HIGH) to GPIO_ACTIVE_LOW. It claimed to "Also sync
device tree with v5.5-rc1", but in the linux tree, these gpios have
always been GPIO_ACTIVE_HIGH ever since this node was introduced
around v4.13 (linux commit 184f39b5).
I'm guessing that the reason for the GPIO_ACTIVE_LOW was to work
around the behaviour of the soft-spi driver back then, which
effectively defaulted to spi-mode 3 and not 0. That was arguably a bug
in the soft-spi driver, which then got fixed in 0e146993bb3 (spi: add
support for all spi modes with soft spi), but that commit then broke
ethernet on this board.
Fix it by setting the gpios as active high, which as a bonus actually
brings us in sync with the .dts in the linux source tree.

With this, ethernet (at least ping and tftp) works as expected from

First idea was to convert "node" parameter to ofnode type inside

is not bijective, in case OF_LIVE flag is enabled, it performs an assert().
So, this leads to update nand_chip struct flash_node field from int to

The chosen alternative is to use strlcpy(), which properly limits the
copy len in the (srclen >= size) case to "size - 1", and which is also
more efficient than the strncpy() byte-by-byte implementation by using
memcpy. The destination string returned by strlcpy() is always NULL
terminated.

strncpy() simply bails out when copying a source string whose size
exceeds the destination string size, potentially leaving the destination
string unterminated.
One possible way to address is to pass MDIO_NAME_LEN - 1 and a
previously zero-initialized destination string, but this is more
difficult to maintain.
