arm64: dts: allwinner: h6: Use - instead of @ for DT OPP entries
DTC and the dt-validate tools report warnings for opp with the format
opp@$frequency: dtc for a missing reg property, and dt-validate since
the binding requires child nodes to have the format opp-$frequency.

Change this to the latter format.

ARM: dts: sun8i-s3: pinecube: Fix CSI DTC warnings
Our CSI endpoint trigger some DTC warnings due to the fact that we're
having a single endpoint that doesn't need any reg property, and since
we don't have a reg property, we don't need the address-cells and
size-cells properties anymore.

Fix those

ARM: dts: sun8i-s3: impetus: Fix the USB PHY ID detect GPIO properties
While the USB PHY Device Tree mandates that the name of the ID detect pin
should be usb0_id_det-gpios, a significant number of device tree use
usb0_id_det-gpio instead.

This was functional because the GPIO framework falls back to the gpio
suffix that is legacy, but we should fix this.

arm64: dts: allwinner: A64: Limit MMC2 bus frequency to 150 MHz
In contrast to the H6 (and later) manuals, the A64 datasheet does not
specify any limitations in the maximum possible frequency for eMMC
controllers.
However experimentation has found that a 150 MHz limit similar to other
SoCs and also the MMC0 and MMC1 controllers on the A64 seems to exist
for the MMC2 controller.

Limit the frequency for the MMC2 controller to 150 MHz in the SoC .dtsi.
The Pinebook seems to be the an odd exception, since it apparently seems
to work with 200 MHz as well, so overwrite this in its board .dts file.

Tested on a Pine64-LTS: 200 MHz HS-200 fails, 150 MHz HS-200 works.

arm64: dts: allwinner: H6: Allow up to 150 MHz MMC bus frequency
The H6 manual explicitly lists a frequency limit of 150 MHz for the bus
frequency of the MMC controllers. So far we had no explicit limits in the
DT, which limited eMMC to the spec defined frequencies, or whatever the
driver defines (both Linux and FreeBSD use 52 MHz here).

Put those maximum frequencies in the SoC .dtsi, to allow higher speed
modes (which still would need to be explicitly enabled, per board).

Tested with an eMMC using HS-200 on a Pine H64. Running at the spec'ed
200 MHz indeed fails with I/O errors, but 150 MHz seems to work stably.

arm64: dts: allwinner: Drop non-removable from SoPine/LTS SD card
The SD card on the SoPine SoM module is somewhat concealed, so was
originally defined as "non-removable".
However there is a working card-detect pin (tested on two different
SoM versions), and in certain SoM base boards it might be actually
accessible at runtime.
Also the Pine64-LTS shares the SoPine base .dtsi, so inherited the
non-removable flag, even though the SD card slot is perfectly accessible
and usable there. (It turns out that just *my* board has a broken card
detect switch, so I originally thought CD wouldn't work on the LTS.)

Drop the "non-removable" flag to describe the SD card slot properly.

arm64: dts: allwinner: H6: properly connect USB PHY to port 0
In recent Allwinner SoCs the first USB host controller (HCI0) shares
the first PHY with the MUSB controller. Probably to make this sharing
work, we were avoiding to declare this in the DT. This has two
shortcomings:
- U-Boot (which uses the same .dts) cannot use this port in host mode
  without a PHY linked, so we were loosing one USB port there.
- It requires the MUSB driver to be enabled and loaded, although we
  don't actually use it.

To avoid those issues, let's add this PHY link to the H6 .dtsi file.
After all PHY port 0 *is* connected to HCI0, so we should describe
it as this.

This makes it work in U-Boot, also improves compatiblity when no MUSB
driver is loaded (for instance in distribution installers).

ARM: dts: sun8i-v3: Add support for the SL631 Action Camera with IMX179
The SL631 is a family of Allwinner V3 action cameras sold under
various names, such as SJCAM SJ4000 Air or F60 Action Camera.

Devices in this family share a common board design but can be found
with different image sensors, including the IMX179 and the OV4689.

This adds support for a common dtsi for the SL631 family as well as
a specific dts for the IMX179 fashion, which will later be populated
with an IMX179 node when a driver is available.

Features that were tested on the device include:
- UART debug
- MMC
- USB peripheral (e.g. g_ether)
- Buttons
- SPI NOR flash

Note that the exact designer/vendor of these boards is unknown.

dt-bindings: arm: sunxi: Add SL631 with IMX179 bindings
This adds documentation for the compatible strings of the
SL631 Action Camera with IMX179.

Note that the device is sold under various different names, such as the
SJCAM SJ4000 Air or F60 Action Camera. This is a similar situation to
the Q8 tablets and just like them, the allwinner vendor is used as
fallback.

ARM: dts: sun8i: Cleanup the Pinecube AXP209 node
This fixes a few things with the Pinecube AXP209 node:
- No compatible is required since it is using an AXP209 (not AXP203)
  according to the schematics and this is what the included axp209.dtsi
  already has;
- The interrupt-controller and #interrupt-cells properties are already
  described in the included axp209.dtsi;
- The interrupt comes through the NMI controller, not directly through
  the GIC.

ARM: dts: sun8i-v3s: Add the V3s NMI IRQ controller
The V3s/V3 has a NMI interrupt controller, mainly used for the AXP209.
Its address follows the system controller block, which was previously
incorrectly described as spanning over 0x1000 address bytes.
Even though this is what the Allwinner documentation indicates,
precedence from other SoCs such as the R40 suggests that this is not
actually the case.

This reduces the system controller address span up to the NMI
controller and adds a node for the controller, with its dedicated
compatible.

While the interrupt number was found in Allwinner's documentation,
the address for the controller is specified in any Allwinner SDK
supporting sun8iw8 (V3/V3s) at:
drivers/power/axp_power/axp20/axp20-board.c

It was tested to work on a V3 board with an AXP209 connected to the
NMI interrupt line.

14e3e989f6 proc mountinfo: make splice available again
Since commit 36e2c7421f ("fs: don't allow splice read/write without
explicit ops") we've required that file operation structures explicitly
enable splice support, rather than falling back to the default handlers.

Most /proc files use the indirect 'struct proc_ops' to describe their
file operations, and were fixed up to support splice earlier in commits
40be821d627c..b24c30c67863, but the mountinfo files interact with the
VFS directly using their own 'struct file_operations' and got missed as
a result.

This adds the necessary support for splice to work for /proc/*/mountinfo
and friends.
