您好!
我是 TI 处理器和器件树的初学者。 66AK2G 处理器的器件树中的"中断"属性让我感到困惑。
例如、在/arch/arm/boot/dts/keystone-k2g.dtsi (https://elixir.bootlin.com/linux/v4.19.94/source/arch/arm/boot/dts/keystone-k2g.dtsi)中
uart0、uart1都具有"中断"属性。 我想知道 GIC_SPI 是什么、164,165是什么意思?
uart0:串行@2530c00{ compatible ="ti、DA830-uart"、"ns16550a"; 电流速度=<115200>; reg-shift =<2>; reg-IO-width =<4>; reg =<0x02530c00 0x100>; interrupts =<GIC_SPI 164 IRQ_TYPE_EDGE_RISING >;Clocks =<&k2g_CLKS 0x5500>;power-domain =<&k2g_PDS 0x2C>;status ="disabled";};uart1:串行@2531000{compatible ="ti、DA830-ps-2c";<reg-width =<IO-c2c>;<reg-width =<IO>; REG =<0x02531000 0x100>; interrupts =<GIC_SPI 165IRQ_TYPE_EDGE_RISING > ;Clocks =<&k2g_CLKS 0x2D 0>;K2 power-domain =<&k2g_PDS 0x2D> ;status ="disabled"; };
