OPi5 i2c interface initialized by wiringPiI2CSetup()

[NicolARun06]

HW:
OrangePi5, and its available I2C dev are: /dev/i2c-1, /dev/i2c-3, /dev/i2c-5.

OS:
Orangepi5_1.1.8_ubuntu_jammy_desktop_xfce_linux6.1.43
the operating system default i2c dev include: /dev/i2c-0 /dev/i2c-10 /dev/i2c-2 /dev/i2c-6 /dev/i2c-7 /dev/i2c-9

But, in wiringOP sources:

wiringOP/wiringPi/wiringPiI2C.h

Line 38 in ce520ea

extern int wiringPiI2CSetup (const int devId) ;

wiringOP/wiringPi/wiringPiI2C.c

Line 228 in ce520ea

device = "/dev/i2c-0" ;

`/*

• wiringPiI2CSetup:
• Open the I2C device, and regsiter the target device

---

*/

int wiringPiI2CSetup (const int devId)
{
int rev ;
const char *device ;
int model;

piBoardId(&model);

device = "/dev/i2c-0" ;

return wiringPiI2CSetupInterface (device, devId) ;

}`

The default I2C device used in code is i2c-0.

That means, this function wiringPiI2CSetup could be initialized successfully (WITHOUT open device failure) in any case, but it cannot obtain the valid register values...
