On the XO-1.75, this node represents a bus interface that operates in slave
mode and thus is only able to accommodate a single subnode; no address
cells are necessary.
The Documentation/devicetree/bindings/spi/spi-controller.yaml binding
prefers that we drop the property instead of setting it to zero.
This fixes a DT validation error:
arch/arm/boot/dts/mmp2-olpc-xo-1-75.dt.yaml: spi@d4037000:
{ ... } is valid under each of {'required': ['spi-slave']},
{'required': ['#address-cells']}
We also need to drop #size-cells:
arch/arm/boot/dts/mmp2-olpc-xo-1-75.dt.yaml: spi@d4037000:
'#address-cells' is a dependency of '#size-cells'

Qualcomm ARM64 DT updates for v5.9
For SM8250 this adds the main pinctrl/gpio block (TLMM), I2C and SPI
controllers, the CPU subsytem watchdog, inter-processor signalling
controller (IPCC), always-on power/clock controller (AOSS),
inter-processor state machine (SMP2P), defines remoteproc controls
for audio, compute and sensor processors and base definition for the
PM8009 PMIC. It also does fix up a few minor issues from the initial
merge of the platform support.
SC7180 and SDM845 gains interconnect paths and performance tables
defined for display, QUP, QSPI, SDHC and CPUs.
SC7180 gains WiFi support and some cleanups related to the modem
remoteproc.
SDM845 gains inline crypto engine support for UFS, LAB/IBB
regulators for powering display panels, remoteproc relocation debug
support
SM8150 gains USB controller support and the two related PHYs, as well as
thermal zones and throttling support.
IPQ8074 gains USB and SDHCI support.
MSM8916 is being cleaned up, gains interconnect providers and Samsung
A2015 gains accelerometer and magnetometer support.
MSM8994 gains PSCI, SDHCI, SPMI support, I2C, SPI, UART gains DMA
support and the DTS files are cleaned up.
The SDM630 platform DTS is at last merged and initial support for Sony
Xperia 10, 10 Plus, XA2, XA2 Plus and XA2 Ultra is added.

Add an OPP (Operating Performance Points) table for the CPU cores for
boards to include to DVFS (Dynamic Voltage & Frequency Scaling) on the
H5. The table originates from Armbian, but the maximum voltage is raised
slightly to account for boards using slightly higher voltages.
The table and tie in to the CPU cores are put in a separate dtsi file
that board files can include to opt in. Or they can define their own
tables if the standard one does not fit.
This has been tested on the Libre Computer ALL-H3-CC-H5 and the Bananapi
M2+ v1.2 H5, both with adequate cooling. The former has a fixed 1.2V
regulator, while the latter has a GPIO controlled regulator switchable
between 1.1V and 1.3V.

The Bananapi M2+ uses a GPIO line to change the effective resistance of
the CPU supply regulator's feedback resistor network. The voltages
described in the device tree were given directly by the vendor. This
turns out to be slightly off compared to the real values.
The updated voltages are based on calculations of the feedback resistor
network, and verified down to three decimal places with a multi-meter.

The device tree currently only assigns the a supply for the first CPU
core, when in reality the regulator supply is shared by all four cores.
This might cause an issue if the implementation does not realize the
sharing of the supply.
Assign the same regulator supply to the remaining CPU cores to address
this.

Commit 1019fe2c72 ("ARM: dts: exynos: Adjust bus related OPPs to the
values correct for Exynos5422 Odroids") changed the parameters of the
OPPs for the FSYS bus. Besides the frequency adjustments, it also removed
the 'shared-opp' property from the OPP table used for FSYS_APB and FSYS
busses.
This revealed that in fact the FSYS bus frequency scaling never worked.
When one OPP table is marked as 'opp-shared', only the first bus which
selects the OPP sets the rate of its clock. Then OPP core assumes that
the other busses have been changed to that OPP and no change to their
clock rates are needed. Thus when FSYS_APB bus, which was registered
first, set the rate for its clock, the OPP core did not change the FSYS
bus clock later.
The mentioned commit removed that behavior, what introduced a regression
on some Odroid XU3 boards. Frequency scaling of the FSYS bus causes
instability of the USB host operation, what can be observed as network
hangs. To restore old behavior, simply disable frequency scaling for the
FSYS bus.

esdhc0 is connected to an eMMC, so it is safe to pass the "no-sdio"/"no-sd"
properties.
esdhc1 is wired to a standard SD socket, so pass the "no-sdio" property.

According to the AR8035 datasheet:
"When using crystal, the clock is generated internally after power is
stable. For a reliable power on reset, suggest to keep asserting the reset
low long enough (10ms) to ensure the clock is stable and clock-to-reset 1ms
requirement is satisfied."
Pass the 'reset-assert-us' property to describe such requirement.
While at it, use the 'reset-gpios' property inside the the mdio
node instead of the deprecated usage of 'phy-reset-gpios'.

imx6q-tbs2910 has an Atheros AR8035 Ethernet PHY at address 4.
The AR8035 provides a 125MHz clock to the ENET_REF_CLK i.MX6 pin.
Improve the Ethernet representation by adding an mdio node with such
information.
This fixes an Ethernet regression in U-Boot as U-Boot AR803X driver now
