## mtk otg调试
1. mk 配otg
	KST_OTG_USB = yes
 
2. dws配中断脚和使能脚
	(根据原理图中“09_POWER_MT6328”页中, "MARK"部分"PSC5425"充电ic中的【OTG】引脚所连接 - 使能脚64)
	(根据原理图中“09_POWER_MT6328”页中, "MARK"部分"PSC5425"充电ic中的【STAT】引脚所连接 - 中断脚0)
	v618_m5501为例
	dws配置pin脚:
			EintMode|Def.Mode	M0|M1|M2|M3|M4|M5|M6|M7|InPull En|InPull SelHigh|Def.Dir|In|Out|OutHigh|VarName1
	GPIO0	1		0:GPIO0 							1		  1				 IN	 	 				GPIO_OTG_IDDIG_EINT_PIN	
	GPIO64			0:GPIO64	1  1  1  1  1  1  1  1  1		  1				 OUT	 0	1	0		GPIO_OTG_DRVVBUS_PIN
	dws配置EINT:
			EINTVar|Debounce Time(ms)|Polarity|Sensitive_Level|Debounce En	
	EINT0	OTG_IDDIG	0				Low		Level			Disable
 
3. dts：
