Uart4_rx_ph4、soc_gpio55_pm4、soc_gpio28_pq1无法input interrupt

[1712127445]

Continuing the discussion from Tegra234-p3701-0004-p3737-0000 GPIO55_M4 Pin Unable to input interrupt:
我遇到同样的问题、
使用jetson linux 35.1.0在orin上，遇到设置uart4_rx_ph4、soc_gpio55_pm4、soc_gpio28_pq1为输入拉高，用作按键使用。配置Linux_for_Tegra/bootloader/t186ref/BCT/tegra234-mb1-bct-pinmux-p3701-0000-a04.dtsi如下

但是这三个gpio一直为低电平：

我是模仿soc_gpio13_pg0实现的，请问这是什么原因导致的？无法配置成拉高状态。

Hi 1712127445,

Are you using the devkit or custom board for AGX Orin?

Could you verify with the latest R35.5.0 and also use pinmux spreadsheet to configure the pinmux?
You should also configure gpio dtsi for the default state.

但是这三个gpio一直为低电平：

It seems there are other driver using these 3 pins.
Do you know which driver use them?
