    芯片为t113,SDK为Tina,问题:我在/sys/devices/platform/soc@3000000/2000c00.pwm/pwm/pwmchip0目录下尝试执行ehco 7 > export,一直提示资源被忙,下面我把out/t113-mq_r/image/.sunxi.dts文件上传,大家帮忙看下是哪里占用了,使用pwm7是PD22引脚

          @whycan 找到问题了,lcd背光使用了pwm通道8即pwm7,没有显式得使用PD22,所以一直没找到哪里被占用了,看了其他帖子有人回答说pwm7和lcd绑定了,我一看还真是的,注释掉就好了,总之还是得谢谢晕哥
