We add device tree files for a couple of additional SoCs in various areas: Allwinner R40/V40 for entertainment, Broadcom Hurricane 2 for networking, Amlogic A113D for audio, and Renesas R-Car V3M for automotive. As usual, lots of new boards get added based on those and other SoCs: - Actions S500 based CubieBoard6 single-board computer - Amlogic Meson-AXG A113D based development board - Amlogic S912 based Khadas VIM2 single-board computer - Amlogic S912 based Tronsmart Vega S96 set-top-box - Allwinner H5 based NanoPi NEO Plus2 single-board computer - Allwinner R40 based Banana Pi M2 Ultra and Berry single-board computers - Allwinner A83T based TBS A711 Tablet - Broadcom Hurricane 2 based Ubiquiti UniFi Switch 8 - Broadcom bcm47xx based Luxul XAP-1440/XAP-810/ABR-4500/XBR-4500 wireless access points and routers - NXP i.MX51 based Zodiac Inflight Innovations RDU1 board - NXP i.MX53 based GE Healthcare PPD biometric monitor - NXP i.MX6 based Pistachio single-board computer - NXP i.MX6 based Vining-2000 automotive diagnostic interface - NXP i.MX6 based Ka-Ro TX6 Computer-on-Module in additional variants - Qualcomm MSM8974 (Snapdragon 800) based Fairphone 2 phone - Qualcomm MSM8974pro (Snapdragon 801) based Sony Xperia Z2 Tablet - Realtek RTD1295 based set-top-boxes MeLE V9 and PROBOX2 AVA - Renesas R-Car V3M (R8A77970) SoC and "Eagle" reference board - Renesas H3ULCB and M3ULCB "Kingfisher" extension infotainment boards - Renasas r8a7745 based iWave G22D-SODIMM SoM - Rockchip rk3288 based Amarula Vyasa single-board computer - Samsung Exynos5800 based Odroid HC1 single-board computer For existing SoC support, there was a lot of ongoing work, as usual most of that concentrated on the Renesas, Rockchip, OMAP, i.MX, Amlogic and Allwinner platforms, but others were also active. Rob Herring and many others worked on reducing the number of issues that the latest version of 'dtc' now warns about. Unfortunately there is still a lot left to do. A rework of the ARM foundation model introduced several new files for common variations of the model. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABAgAGBQJaDhcfAAoJEGCrR//JCVIngu0QAI2ntVotaOAOaCurNCnoVwI1 j+eKwHGTawQRcSHWN8C+p4FzzaOmw+vvbOyewky8PWaDOCkK6yWEHRf3hb2la2jw j9prht28R1RAHIRPuah4SxKHYoT4VW9q/2hMHJ2BiNDOMX54xE7j2cUvWSsIRz5o id2QqKsp2OIDNQAXAA4N25FjdBCYvSik80panSdJITtJODIj6UfmcXSgqkoQ3TTV rwVyFtryl9Si3eyZYcfB2/0ILKuaMC8gl7IX9z+PkRqu9XN7i6bZKZlMMtpJqX3u Ad89kLkFqNhiwZ77bIoRRl+0NEoSu5hTPLHRqghS6gPfDY2JT6igf0rGC8twjfea fzGOBWr6NlIlUmR4smS0GyE/3YsfOQvYWjE+zx5qkmay30TORVTZBzsBR+kQJzKK tnbO1zvst1ECtk9e8np0di4NAo9rwM37dxpu4aspP1Umxw1K68VSNE3RhGl8UUwW oNvHa8hD8Ck0QDBNltrkmKBVoIYKRU3XhXrRXVjRQdu6Xitml0XYBi80V0h33EE3 162UXDEMu1/aqRRZUtKw7+yozT8fqOHjH8Zrv2zCVGg0HEwVohcWv/BPXbrg0abJ wXYS8VocZJP6Nb4FQMe+cRbBUHoBgBQqbsF60tWiYsjv0zoc5hogLWcZYqzDcIO6 06OBR3HgUW27urUn/JBu =TnSo -----END PGP SIGNATURE----- Merge tag 'armsoc-dt' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM device-tree updates from Arnd Bergmann: "We add device tree files for a couple of additional SoCs in various areas: Allwinner R40/V40 for entertainment, Broadcom Hurricane 2 for networking, Amlogic A113D for audio, and Renesas R-Car V3M for automotive.

Allwinner A31 DMA Controller
|
|
|
|
This driver follows the generic DMA bindings defined in dma.txt.
|
|
|
|
Required properties:
|
|
|
|
- compatible: Must be one of
|
|
"allwinner,sun6i-a31-dma"
|
|
"allwinner,sun8i-a23-dma"
|
|
"allwinner,sun8i-a83t-dma"
|
|
"allwinner,sun8i-h3-dma"
|
|
"allwinner,sun8i-v3s-dma"
|
|
- reg: Should contain the registers base address and length
|
|
- interrupts: Should contain a reference to the interrupt used by this device
|
|
- clocks: Should contain a reference to the parent AHB clock
|
|
- resets: Should contain a reference to the reset controller asserting
|
|
this device in reset
|
|
- #dma-cells : Should be 1, a single cell holding a line request number
|
|
|
|
Example:
|
|
dma: dma-controller@1c02000 {
|
|
compatible = "allwinner,sun6i-a31-dma";
|
|
reg = <0x01c02000 0x1000>;
|
|
interrupts = <0 50 4>;
|
|
clocks = <&ahb1_gates 6>;
|
|
resets = <&ahb1_rst 6>;
|
|
#dma-cells = <1>;
|
|
};
|
|
|
|
------------------------------------------------------------------------------
|
|
For A64 DMA controller:
|
|
|
|
Required properties:
|
|
- compatible: "allwinner,sun50i-a64-dma"
|
|
- dma-channels: Number of DMA channels supported by the controller.
|
|
Refer to Documentation/devicetree/bindings/dma/dma.txt
|
|
- all properties above, i.e. reg, interrupts, clocks, resets and #dma-cells
|
|
|
|
Optional properties:
|
|
- dma-requests: Number of DMA request signals supported by the controller.
|
|
Refer to Documentation/devicetree/bindings/dma/dma.txt
|
|
|
|
Example:
|
|
dma: dma-controller@1c02000 {
|
|
compatible = "allwinner,sun50i-a64-dma";
|
|
reg = <0x01c02000 0x1000>;
|
|
interrupts = <GIC_SPI 50 IRQ_TYPE_LEVEL_HIGH>;
|
|
clocks = <&ccu CLK_BUS_DMA>;
|
|
dma-channels = <8>;
|
|
dma-requests = <27>;
|
|
resets = <&ccu RST_BUS_DMA>;
|
|
#dma-cells = <1>;
|
|
};
|
|
------------------------------------------------------------------------------
|
|
|
|
Clients:
|
|
|
|
DMA clients connected to the A31 DMA controller must use the format
|
|
described in the dma.txt file, using a two-cell specifier for each
|
|
channel: a phandle plus one integer cells.
|
|
The two cells in order are:
|
|
|
|
1. A phandle pointing to the DMA controller.
|
|
2. The port ID as specified in the datasheet
|
|
|
|
Example:
|
|
spi2: spi@1c6a000 {
|
|
compatible = "allwinner,sun6i-a31-spi";
|
|
reg = <0x01c6a000 0x1000>;
|
|
interrupts = <0 67 4>;
|
|
clocks = <&ahb1_gates 22>, <&spi2_clk>;
|
|
clock-names = "ahb", "mod";
|
|
dmas = <&dma 25>, <&dma 25>;
|
|
dma-names = "rx", "tx";
|
|
resets = <&ahb1_rst 22>;
|
|
};
