在代碼中我如何獲取 &tlmm 39 0 以用作控制，請大俠百忙中指導一下思路，感謝

gpios = <&tlmm 26 0>,<&tlmm 40 0>，
<&tlmm 39 0>,
<&tlmm 300 0>;
這個怎么獲取gpios中的 tlmm 39
uj5u.com熱心網友回復：
不是有專門的函式通過節點去讀取dts嗎uj5u.com熱心網友回復：
您 是說的 nine_zero_det_gpio = of_get_named_gpio(node, "ailiving,nine-zero-det", 0); 但是我不知道怎樣關聯起來，如果對于任意一個平臺，比如RK mtk msm 平臺，我直接使用 gpio號，可以不，比如 ，直接申請gpio_request(39);
gpio_direction_output(39,1);
有沒有大問題

感謝回復與支持uj5u.com熱心網友回復：
每個平臺gpio號的命名規則不一樣，獲取方式也不盡一樣，我們不一定說一定要從dts獲取，像你之前說的那種應該也是可以的，直接從代碼里面寫，怕有問題你可以寫個代碼簡單測驗下uj5u.com熱心網友回復：
好的。感謝感謝轉載請註明出處，本文鏈接：https://www.uj5u.com/qita/9277.html
