How to find GPIO on my motherboard. I want describe gpio in device tree like this:
&gpio { status = "okay";
gpio-line-names =
/*A0-A7*/ "BMC_CPLD_FPGA_SEL","","","","","","","",
/*B0-B7*/ "","BMC_DEBUG_EN","","","","BMC_PPIN","PS_PWROK",
"IRQ_PVDDQ_GHJ_VRHOT_LVT3",
/*C0-C7*/ "","","","","","","","",
/*D0-D7*/ "BIOS_MRC_DEBUG_MSG_DIS","BOARD_REV_ID0","",
"BOARD_REV_ID1","IRQ_DIMM_SAVE_LVT3","BOARD_REV_ID2",
"CPU_ERR0_LVT3_BMC","CPU_ERR1_LVT3_BMC",
But i dont have any documentation about my motherboard. Maybe any software cat found GPIO and thier names ??
