project:cfg:BoardConfig_IPC: Added fastboot BoardConfig file and firmware post-scripts, distinguishing between the BoardConfigs for Luckfox Pico Pro and Luckfox Pico Max. project:app: Added fastboot_client and rk_smart_door for quick boot applications; updated rkipc app to adapt to the latest media library. media:samples: Added more usage examples. media:rockit: Fixed bugs; removed support for retrieving data frames from VPSS. media:isp: Updated rkaiq library and related tools to support connection to RKISP_Tuner. sysdrv:Makefile: Added support for compiling drv_ko on Luckfox Pico Ultra W using Ubuntu; added support for custom root filesystem. sysdrv:tools:board: Updated Buildroot optional mirror sources, updated some software versions, and stored device tree files and configuration files that undergo multiple modifications for U-Boot and kernel separately. sysdrv:source:mcu: Used RISC-V MCU SDK with RT-Thread system, mainly for initializing camera AE during quick boot. sysdrv:source:uboot: Added support for fastboot; added high baud rate DDR bin for serial firmware upgrades. sysdrv:source:kernel: Upgraded to version 5.10.160; increased NPU frequency for RV1106G3; added support for fastboot.

MOXA ART DMA Controller
|
|
|
|
See dma.txt first
|
|
|
|
Required properties:
|
|
|
|
- compatible : Must be "moxa,moxart-dma"
|
|
- reg : Should contain registers location and length
|
|
- interrupts : Should contain an interrupt-specifier for the sole
|
|
interrupt generated by the device
|
|
- #dma-cells : Should be 1, a single cell holding a line request number
|
|
|
|
Example:
|
|
|
|
dma: dma@90500000 {
|
|
compatible = "moxa,moxart-dma";
|
|
reg = <0x90500080 0x40>;
|
|
interrupts = <24 0>;
|
|
#dma-cells = <1>;
|
|
};
|
|
|
|
|
|
Clients:
|
|
|
|
DMA clients connected to the MOXA ART 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. Peripheral identifier for the hardware handshaking interface.
|
|
|
|
Example:
|
|
Use specific request line passing from dma
|
|
For example, MMC request line is 5
|
|
|
|
mmc: mmc@98e00000 {
|
|
compatible = "moxa,moxart-mmc";
|
|
reg = <0x98e00000 0x5C>;
|
|
interrupts = <5 0>;
|
|
clocks = <&clk_apb>;
|
|
dmas = <&dma 5>,
|
|
<&dma 5>;
|
|
dma-names = "tx", "rx";
|
|
};
