Vendor of the GTA04 boards is and always was
Golden Delicious Computers GmbH&Co. KG, Germany
and not Texas Instruments.
Maybe, TI was references here because the GTA04 was based on
the BeagleBoard design which is designated as "ti,omap3-beagle".
While we are looking at vendors of omap3 based devices, we also
add the record for OpenPandora. The DTS files for the pandora
device already make use of it.

OMAP processors support 32 channels but there is no check or
inspect this except booting a device and looking at dmesg reports
of not available channels.
Recently some more subsystems with DMA (aes1+2) were added filling
the list of dma channels beyond the limit of 32 (even if other
parameters indicate 96 or 128 channels). This leads to random
subsystem failures i(e.g. mcbsp for audio) after boot or boot
messages that DMA can not be initialized.
Another symptom is that
/sys/kernel/debug/dmaengine/summary
has 32 entries and does not show all required channels.
Fix by disabling unused (on the GTA04 hardware) mcspi1...4.
Each SPI channel allocates 4 DMA channels rapidly filling
the available ones.
Disabling unused SPI modules on the OMAP3 SoC may also save
some energy (has not been checked).

This is a more interesting use of DT Overlays than the previous patches.
Here we have two touchscreen modules. Each is compatible with, and can be
attached to, either of the two AM57xx IDK development board variants
(AM571x or AM572x).
Due to the way the extension header was wired on the development boards,
the touch sensor on the touchscreen modules will connect to different
SoC pins when connected. For this the touch sensor is modeled as an
additional overlay that is specific to the development board for which it
is connected.
Basically the LCD overlay can be swapped, but the touchscreen overlay
that attaches to the LCD must be used with the corresponding base DT
and not to the LCD.

The A3 revision of the AM57xx GP EVM has the same EVM feature set as the
original but is paired with an updated revision C BeagleBoard X15.
DT Overlays allow us to model this in the same way, we simply apply the

The AM57xx GP EVM boards are built on top the AM57xx BeagleBoard-X15.
The EVM extends the BeagleBoard by adding a touchscreen, some buttons,
and a handful of peripheral extension slots.
Being a plugin extension of an existing standalone board; we define
the am57xx-evm as a composite-DTB of the base am57xx-beagle-x15
and a new am57xx-evm overlay.

and out of these, most are for the Qualcomm and NXP platforms, including:
- A missing "reserved-memory" property on LG G Watch R that
is needed to prevent clashing with firmware
- Annotations for cache coherency on multiple machines
- Corrections for pinctrl, regulator, clock, iommu and power domain
properties for i.MX and Qualcomm to correctly reflect the
hardware settings
- Firmware file names on multiple machines

- An incompatible change to the qcom vadc driver requires adding

- Fix EQoS PHY reset GPIO by dropping the deprecated/wrong property
and switch to the new bindings.
- A fix for PCI bus address translation Tegra194 and Tegra234.
There are also a couple of device driver fixes, addressing
- A race condition in the amdtee driver
- A performance regression in the Qualcomm 'llcc' driver
- An unitialized variable use NXP i.MX "weim" driver
- Error handling issues in Qualcomm "rmtfs", and "scm"

The Lctech Pi F1C200s (also previously known under the Cherry Pi brand)
is a small development board with the Allwinner F1C200s SoC. This is the
same as the F1C100s, but with 64MB instead of 32MB co-packaged DRAM.
Alongside the obligatory micro-SD card slot, the board features a
SPI-NAND flash chip, LCD and touch connectors, and unpopulated
expansion header pins.
There are two USB Type-C ports on the board: One supplies the power, also
connects to the USB MUSB OTG controller port. The other one is connected
to an CH340 USB serial chip, which in turn is connected to UART1.
Add a devicetree file, so that the board can be used easily.

Replace of_get_address() and of_translate_address() with single call
to of_address_to_resource(). With this, use ioremap() instead of
of_iomap() which would parse "reg" a second time.

The MXIII Plus uses an Ampak AP6330 Bluetooth and WiFi combo chip.
Bluetooth is connected to &uart_A and requires toggling GPIOX_20.
WiFi can be routed to either &sdhc or &sdio. Route WiFi to &sdhc
since &sdio is already connected to the SD card. Additionally WiFi
requires toggling GPIOX_11 and GPIOAO_6 as well as enabling the 32kHz
clock signal.

GPIOX_10 can generate a 32768Hz signal when enabling the "xtal_32k_out"
group with the xtal function. This is typically used as LPO clock for

The actual intention is that no dynamic relocation exists in the VDSO. For
this the VDSO build validates that the resulting .so file does not have any
relocations which are specified via $(ARCH_REL_TYPE_ABS) per architecture,
which is fragile as e.g. ARM64 lacks an entry for R_AARCH64_RELATIVE. Aside
of that ARCH_REL_TYPE_ABS is a misnomer as it checks for relative
relocations too.
However, some GNU ld ports produce unneeded R_*_NONE relocation entries. If
a port fails to determine the exact .rel[a].dyn size, the trailing zeros
become R_*_NONE relocations. E.g. ld's powerpc port recently fixed
https://sourceware.org/bugzilla/show_bug.cgi?id=29540). R_*_NONE are
generally a no-op in the dynamic loaders. So just ignore them.
Remove the ARCH_REL_TYPE_ABS defines and just validate that the resulting
.so file does not contain any R_* relocation entries except R_*_NONE.

To support the detach feature, add a new mailbox channel to inform
the remote processor on a detach. This signal allows the remote processor
firmware to stop IPC communication and to reinitialize the resources for
a re-attach.

same for stm32mp15x-dkx boards.

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is (mostly) ignored
and this typically results in resource leaks. To improve here there is a
quest to make the remove callback return void. In the first step of this
quest all drivers are converted to .remove_new() which already returns
void.
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.
