2023-03-30docs: move x86 documentation into Documentation/arch/Jonathan Corbet1-1/+1
Move the x86 documentation under Documentation/arch/ as a way of cleaning up the top-level directory and making the structure of our docs more closely match the structure of the source directories it describes. All in-kernel references to the old paths have been updated.

2023-03-30ARM: sh-mobile: Use of_cpu_node_to_id() to read CPU node 'reg'Rob Herring1-20/+16
Replace open coded CPU nodes reading of "reg" and translation to logical ID with of_cpu_node_to_id(). The original code called of_parse_phandle() CONFIG_NR_CPUS times regardless of the length of 'cpus'. Optimize the loop to bail out once of_parse_phandle() fails as the end of 'cpus' property has been reached.

2023-03-30ARM: dts: marzen: Add slide switchesGeert Uytterhoeven1-0/+63
Describe the four General Purpose Switches on the Marzen development board, so they can be used for user input and/or for wake-up from s2ram. The GPIO block on R-Car H1 does not support triggering interrupts on both edges of a changing input signal, hence one cannot use gpio-keys with gpios properties. Instead, one of two alternatives needs to be used: 1. Use gpio-keys with interrupts instead of gpios properties, at the expense of receiving only key presses (release events will be auto-generated), 2. Use gpio-keys-polled with gpios properties, at the expense of making these keys unusable as wake-up sources. As the DTS for the Marzen development board serves mainly as an example, the approach taken is to use the first alternative for the first two switches, and the second alternative for the last two switches.

2023-03-27ARM: dts: sunxi: add MangoPi MQ-R-T113 boardAndre Przywara3-0/+162
The MangoPi MQ-R-T113 is a small SBC with the Allwinner T113-s3 SoC. The SoC features two Arm Cortex-A7 cores and 128 MB of co-packaged DDR3 DRAM. The board adds mostly connectors and the required regulators, plus a Realtek RTL8189FTV WiFi chip. Power comes in via a USB-C connector wired as a peripheral, and there is a second USB-C connector usable as a host port. Add a .dtsi file describing most of the board's peripherals, and include that from the actual board .dts file. This allows to re-use the .dtsi for the MQ-R-F113 RISC-V variant of that board.

We include the core .dtsi directly from the riscv DT directory.

2023-03-27ARM: dts: gta04: fix excess dma channel usageH. Nikolaus Schaller1-0/+16
OMAP processors support 32 channels but there is no check or inspect this except booting a device and looking at dmesg reports of not available channels. Recently some more subsystems with DMA (aes1+2) were added filling the list of dma channels beyond the limit of 32 (even if other parameters indicate 96 or 128 channels). This leads to random subsystem failures i(e.g. mcbsp for audio) after boot or boot messages that DMA can not be initialized. Another symptom is that /sys/kernel/debug/dmaengine/summary has 32 entries and does not show all required channels. Fix by disabling unused (on the GTA04 hardware) mcspi1...4. Each SPI channel allocates 4 DMA channels rapidly filling the available ones. Disabling unused SPI modules on the OMAP3 SoC may also save some energy (has not been checked).

2023-03-27ARM: dts: am57xx-idk: Add IDK displays and touchscreensAndrew Davis5-0/+197
This is a more interesting use of DT Overlays than the previous patches. Here we have two touchscreen modules. Each is compatible with, and can be attached to, either of the two AM57xx IDK development board variants (AM571x or AM572x). Due to the way the extension header was wired on the development boards, the touch sensor on the touchscreen modules will connect to different SoC pins when connected. For this the touch sensor is modeled as an additional overlay that is specific to the development board for which it is connected. Basically the LCD overlay can be swapped, but the touchscreen overlay that attaches to the LCD must be used with the corresponding base DT and not to the LCD.

2023-03-27ARM: dts: ti: Add AM57xx GP EVM Rev A3 board supportAndrew Davis1-0/+2
The A3 revision of the AM57xx GP EVM has the same EVM feature set as the original but is paired with an updated revision C BeagleBoard X15. DT Overlays allow us to model this in the same way, we simply apply the EVM overlay to the Rev C BeagleBoard to create the Rev A3 AM57xx GP EVM.

2023-03-27ARM: dts: ti: Add AM57xx GP EVM board supportAndrew Davis2-0/+129
The AM57xx GP EVM boards are built on top the AM57xx BeagleBoard-X15. The EVM extends the BeagleBoard by adding a touchscreen, some buttons, and a handful of peripheral extension slots. Being a plugin extension of an existing standalone board; we define the am57xx-evm as a composite-DTB of the base am57xx-beagle-x15 and a new am57xx-evm overlay.

2023-03-27ARM: OMAP2+: Use of_property_read_bool() for boolean propertiesRob Herring1-3/+3
It is preferred to use typed property access functions (i.e. of_property_read_<type> functions) rather than low-level of_get_property/of_find_property functions for reading properties. Convert reading boolean properties to to of_property_read_bool().
