xiic-i2c fff0e00000.i2c: input clock not found.

[marmar]

hello everyone

at the moment I am working on adding axi iic to openpiton.

my final goal is to be able to read the temperature from an i2c device in linux.

I have been getting "input clock not found" in the boot loader:

[   32.760851] i2c /dev entries driver
[   32.768047] xiic-i2c fff0e00000.i2c: input clock not found.

[   32.914074] xiic-i2c fff0e00000.i2c: input clock not found.

I was also wondering do I have to add an external pull-up to the sea and scp ports in genesys2? I found many posts related to axi iic suggesting that.

I have added these to my kernel config:

CONFIG_I2C_XILINX=y
CONFIG_I2C=y
CONFIG_OF_I2C=y
CONFIG_I2C_CHARDEV=y
CONFIG_I2C_BOARDINFO=y
CONFIG_XILINX_I2C=y
CONFIG_I2C_OCORES=y
CONFIG_COMMON_CLK_XLNX_CLKWZRD=y

I attached the device tree file too.

I am new to these things and will appreciate any help.

thank you!

I managed to solve the issue by updating the linux kernel to 5.16 and above.
