Take below as example.
&main_uart5 {
pinctrl-names = "default";
pinctrl-0 = <&main_uart5_pins_default>;
dmas = <&main_pktdma 0x4405 0>, <&main_pktdma 0xc405 0>;
dma-names = "rx", "tx";
status = "okay";
};
How to determine the parameter of dmas, what is 0x4405 and 0xc405? what is 0? where to find it in TRM?
Somebody said the first one is PSIL ID, the second one is DMA channel ID, they are hardware ID, but I did not find it anywhere.
Is there a table for each peripheral? give a peripheral, how to configure DMA start from zero?
