ASPEED AST2600 provides one PCIe RC with 5GT/s and AST2700 provides three
PCIe RC for two 16GT/s and one 5GT/s. All of these RCs have just one Root
Port to connect to PCIe device. And also have Mem, I/O access, legacy
interrupt and MSI.

Document the device tree bindings for the DWC3 USB controller found in
Google Tensor SoCs, starting with the G5 generation (codename: laguna).
The Tensor G5 silicon represents a complete architectural departure from
previous generations (like gs101), including entirely new clock/reset
schemes, top-level wrapper and register interface. Consequently,
existing Samsung/Exynos DWC3 USB bindings are incompatible, necessitating
this new device tree binding.
The USB controller on Tensor G5 is based on Synopsys DWC3 IP and features
Dual-Role Device single port with hibernation support.

i.MX95 PCIes have two reference clock inputs: one from internal PLL.
It's wired inside chip and present as "ref" clock. It's not an optional
clock. The other from off chip crystal oscillator. The "extref" clock
refers to a reference clock from an external crystal oscillator through
the CLKIN_N/P pair PADs. It is an optional clock, relied on the board
design.
Add additional optional external reference clock input for i.MX95 PCIes.

qcs8300
The gcc_aux_clk is not required by the PCIe PHY on qcs8300 and is not
specified in the device tree node. Hence, move the qcs8300 phy
compatibility entry into the list of PHYs that require six clocks.
Removed the phy_aux clock from the PCIe PHY binding as it is no longer
used by any instance.

Add support for the APDMA IP found in all of the SoC generations
that are currently supported upstream; this includes:
- MT8173, MT8183, fully compatible with MT6577 (32-bits)
- MT7988, MT8186, MT8188, MT8192, MT8195 and MT6835 (34-bits)
- MT6991, MT8196 and MT6985 (35-bits)
...where:
- MT6835 is the first SoC where the AP_DMA IP supports 34-bits
addressing; and
- MT6985 is the first SoC where the AP_DMA IP supports 35-bits
addressing.
While at it, also add myself in the maintainers list.

While this property wants to express a capability of the hardware,
this is only used by the driver itself to vary the DMA bits during
probe.
Different hardware shall instead have different compatible strings.
Following the driver cleanup and the introduction of a specific
compatible string for the APDMA IP version found in MT6795, set
the "mediatek,dma-33bits" vendor property as deprecated.

While it is true that this SoC is compatible with the MT6577 APDMA
IP, that is valid only when the IP is used in 32-bits addressing
mode, and, by the way there is no good reason to do so.
Since the APDMA IP in MT6795 supports 33 bits addressing, this
means that it is a newer revision compared to the one found in
MT6577, hence only partially compatible with it.
Allow nodes to specify "mediatek,mt6795-uart-dma" as their only
compatible in the case of MT6795; this is done in lieu of the fact
that there are other SoCs integrating the same version of this IP
as MT6795, and those will eventually get their own compatible that
expresses full compatibility with this SoC.

- Main memory, caches and the possiblie control given by the hardware.
- What could happen by putting critical hardware behind USB or VirtIO.
- Allowing real-time tasks to consume the CPU entirely without giving
the system some time to breath.
- Networking with what the kernel provides.

Don't claim that /dev/sr<N> device names for SCSI CD-ROM drives are
deprecated and don't recommend /dev/scd<N> alternate names for them.
/dev/scd<N> device names for SCSI CD-ROM drives are not in use for more
than a decade, see commit [1] that was a part of udev release 174.
Earlier, related rules were volatile, sometimes /dev/scd<N> were syminks
to /dev/sr<N>, sometimes vice versa.
Recognizing of root=/dev/scd<N> kernel command line argument was removed
in kernel 2.5.45 [2].
In the docs /dev/scd<N> became recommended names in 2.6.9 [3].
Mention of these names appeared much earlier in 1.3.22 [4].

Each CMU (with the exception of cmu_top) has a corresponding sysreg bank
that contains the BUSCOMPONENT_DRCG_EN and optional MEMCLK registers.
The BUSCOMPONENT_DRCG_EN register enables dynamic root clock gating of
bus components and MEMCLK gates the sram clock.
Now the clock driver supports automatic clock mode, to fully enable dynamic
root clock gating it is required to configure these registers. Update the
bindings documentation so that all CMUs (with the exception of
gs101-cmu-top) have samsung,sysreg as a required property.
Note this is NOT an ABI break, as if the property isn't specified the
clock driver will fallback to the current behaviour of not initializing
the registers. The system still boots, but bus components won't benefit
from dynamic root clock gating and dynamic power will be higher (which has
been the case until now anyway).
Additionally update the DT example to included the correct CMU size as
registers in that region are used for automatic clock mode.

Merge series from cy_huang@richtek.com:
This patch series add rt8092 regulator support.
|

The A523 has four SPI controllers. One of them supports MIPI DBI mode
in addition to standard SPI.
Compared to older generations, this newer controller now has a combined
counter for the RX FIFO ad buffer levels. In older generations, the
RX buffer level was a separate bitfield in the FIFO status register.
In practice this difference is negligible. The buffer is mostly
invisible to the implementation. If programmed I/O transfers are limited
to the FIFO size, then the contents of the buffer seem to always be
flushed over to the FIFO. For DMA, the DRQ trigger levels are only tied
to the FIFO levels. In all other aspects, the controller is the same as
the one in the R329.
Add new compatible strings for the new controllers.

Adds binding for digital Honeywell ABP2 series pressure and temperature
sensors.
The i2c address is hardcoded and depends on the part number.
There is an optional interrupt that signals the end of conversion.

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

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.

Pull spi fixes from Mark Brown:
"A small collection of fixes for various SPI drivers, plus a relaxation
of constraints in the DT for the DesignWare controller to reflect
hardware that's been seen.
There's several fixes for the Cadence QuadSPI driver since a fix
during the last release made some existing issues with error handling
during probe more readily visible"
* tag 'spi-fix-v6.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi:
spi: mt65xx: Use IRQF_ONESHOT with threaded IRQ
spi: dt-bindings: snps,dw-abp-ssi: Allow up to 16 chip-selects
spi: cadence-quadspi: Fix clock disable on probe failure path

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.
