The device has interrupts allocated according to the datasheet, and
the devicetree already defines the interrupt property. Address existing

Add devicetree bindings for the ADL8113 Low Noise Amplifier.
The bindings include support for specifying gain values of external
amplifiers connected to the two external bypass paths (A and B). These
optional properties allow the gain values to be selectable via the
hardwaregain attribute, enabling complete devicetree description of
the signal chain including external components.

Add device tree bindings documentation for the Texas Instruments
ADS131M0x analog-to-digital converters. This family includes the ADS131M02,
ADS131M03, ADS131M04, ADS131M06, and ADS131M08 variants.
These variants differ primarily in the number of supported channels
(2, 3, 4, 6, and 8, respectively), which requires separate compatible
strings to validate the channel nodes.

Lite board
Append "starfive,jh7110" compatible to VisionFive 2 Lite and VisionFive 2
Lite eMMC boards in the least-compatible end of the list.
Appending "starfive,jh7110" reduces the number of compatible strings to
check in the OpenSBI platform driver. JH-7110S SoC on these boards is the
same as JH-7110 SoC however rated for thermal, voltage, and frequency
characteristics for a maximum of 1.25GHz operation.

Commit 8a55fbe4c94d ("dt-bindings: interconnect: add reg and clocks
properties to enable QoS on sa8775p") claims that all interconnects have
clocks and MMIO address space, but that is just not true. Only few
have. Bindings should restrict properties and should not allow
specifying non-existing hardware description, so fix missing constraints
for 'reg' and 'clocks'.

Introduce JEDEC compliant DDR bindings, that use new memory-props binding.
The DDR4 compatible can be made of explicit vendor names and part
numbers or be of the form "ddrX-YYYY,AAAA...-ZZ" when associated with an
SPD, where (according to JEDEC SPD4.1.2.L-6):
- YYYY is the manufacturer ID
- AAAA... is the part number
- ZZ is the revision ID
The former form is useful when the SDRAM vendor and part number are
known, for example, when memory is soldered on the board.
The latter form is useful when SDRAM nodes are created at runtime by
boot firmware that doesn't have access to static part number information.

LPDDR and DDR bindings are SDRAM types and are likely to share the same
properties (at least for density, io-width and reg).
To avoid bindings duplication, factorise the properties.
The compatible description has been updated because the MR (Mode
registers) used to get manufacturer ID and revision ID are not present
in case of DDR.
Those information should be in a SPD (Serial Presence Detect) EEPROM in
case of DIMM module or are known in case of soldered memory chips as
they are in the datasheet of the memory chips.

Merge series from CL Wang <cl634@andestech.com>:
This series adds support for the Andes ATCSPI200 SPI controller.
|
|
Merge series from Haibo Chen <haibo.chen@nxp.com>:
XSPI is a flexible SPI host controller which supports up to
2 external devices (2 CS). It support Single/Dual/Quad/Octal
mode data transfer.
The difference between XSPI and Flexspi is XSPI support
multiple independent execution environments (EENVs) for HW
virtualization with some limitations. Each EENV has its own
interrupt and its own set of programming registers that exists
in a specific offset range in the XSPI memory map.
The main environment (EENV0) address space contains all of the
registers for controlling EENV0 plus all of the general XSPI
control and programming registers. The register mnemonics for
the user environments (EENV1 to EENV4) have "_SUB_n" appended
to the mnemonic for the corresponding main-environment register.
Current driver based on EENV0, which means system already give
EENV0 right to linux.
This driver use SPI memory interface of the SPI framework to issue
flash memory operations. Tested this driver with mtd_debug and
UBIFS on NXP i.MX943 EVK board which has one MT35XU512ABA spi nor
flash. NOw this driver has the following key features:
- Support up to OCT DDR mode
- Support AHB read
- Support IP read and IP write
- Support two CS

Running the full 'make dt_binding_check' is slow. A shortcut is to set
DT_SCHEMA_FILES env variable to a substring of DT schema files to test.
It both limits which examples are validated and which schemas are used
to validate the examples. This is a problem because errors from other
schemas are missed. What makes validation slow is checking all examples,
so we really just need a way to test a single example.
Add a %.yaml target to validate the schema and validate the example:
make example-schema.yaml
The behavior for 'make dt_binding_check DT_SCHEMA_FILES=example-schema'
is unchanged. Really it should mirror dtbs_check and validate all the
examples with a subset of schemas, but there are lots of users of
expecting the existing behavior.

Add documentation for the serial communication interface (RSCI) found on
the Renesas RZ/G3E (R9A09G047) SoC. The RSCI IP on this SoC is identical
to that on the RZ/T2H (R9A09G077) SoC, but it has a 32-stage FIFO compared
to 16 on RZ/T2H. It supports both FIFO and non-FIFO mode operation. RZ/G3E
has 6 clocks(5 module clocks + 1 external clock) compared to 3 clocks
(2 module clocks + 1 external clock) on RZ/T2H, and it has multiple resets.
It has 6 interrupts compared to 4 on RZ/T2H.

EHCI and OHCI controllers can be DMA coherent on some platforms, so
allow the "dma-coherent" property.

configfs
When using f_midi from configfs the USB MIDI interface string is hardcoded
to 'MIDI function'.
This USB string descriptor is used by some third-party OS or software to
display the name of the MIDI device
Since we add an additional string option a new macro block was created to
factorize declarations

Add the "aspeed,ast2700-usb-vhub" compatible. The ast2700 vhub
controller requires an reset, so make the "resets" property
mandatory for this compatible to reflect the hardware requirement.

At least the Microchip Sparx5 supports up to 16 chip-selects, so
increase the maximum. The pattern for the child unit-address was
unconstrained, so update it to match the maximum number of
chip-selects.
