widora BIT3 更新源码后 WLED/P0_LED等LED无法控制

[Edward]

更新openwrt源码后，WLED_N、P0_LED无法控制，通过reg命令读取WLED
root@Widora:/etc# reg r 0x10000064
add:0x10000064 = 0x550
网寄存器里面写0x552，WLED电平没有反应。

P1_LED到P4_LED可以控制。

@edward 你丢了一步，忘了设置GPIO的DIR和DATA

新的源码中，WLED_N、P0_LED的IO口有作为他用吗？

设备树文件是这样配置的。

     pinctrl {
	state_default: pinctrl0 {

		gpio {
			ralink,group = "gpio";
			ralink,function = "gpio";
		};

		perst {
			ralink,group = "perst";
			ralink,function = "gpio";
		};

		refclk {
			ralink,group = "refclk";
			ralink,function = "gpio";
		};

		i2s {
			ralink,group = "i2s";
			ralink,function = "gpio";
		};

		spis {
			ralink,group = "spis";
			ralink,function = "gpio";
		};
		
		wled_an {
			ralink,group = "wled_an";
			ralink,function = "gpio";
		};
	
		ephy_p0{
			ralink,group = "ephy_p0";
			ralink,function = "gpio";
		};
		ephy_p1 {
			ralink,group = "ephy_p1";
			ralink,function = "gpio";
		};
		ephy_p2 {
			ralink,group = "ephy_p2";
			ralink,function = "gpio";
		};
		ephy_p3 {
			ralink,group = "ephy_p3";

		};
		ephy_p4 {

		};
		wdt {
			ralink,group = "wdt";
			ralink,function = "gpio";

	};
};

@edward 我们这边的源码中，WLED和LINK0一只是把GPIO_MODE寄存器调整到PHY的那边，所以看到的闪烁灯都是PHY直驱的，不是openwrt系统驱动的。
你的这个dts的调整，相当于注册成gpio来主动驱动，估计你要实用net-trig包来驱动。
