Even though it translates to the same thing down to the binary level, we should have an array of 2 number cells to describe each voltage state, which in turns create a validation warning. Let's fix this. Signed-off-by:

The CPU thermal zone is called on most of the older DTSI cpu_thermal. However, the underscore is an invalid character for a node name and the thermal zone binding explicitly requires that zones are called *-thermal. Let's fix it. Signed-off-by:

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. Fixes: 22be992f ("arm64: allwinner: a64: Increase the MMC max frequency") Signed-off-by:

Andre Przywara authored
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. Fixes: 8f54bd15 ("arm64: allwinner: h6: add device tree nodes for MMC controllers") Signed-off-by:

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.

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).

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.

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. Signed-off-by:

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.

Paul Kocialkowski authored
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.

Since commit 36e2c742 ("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 40be821d..b24c30c6, 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. Reported-by:
