How to use the I2C on ATOM Bay trail Board?

        My board used E3845 and I used I2C0 to link one pca9534 to be used as an I2c to GPIO and one AT24HC04B to be used to save something important. The other I2Cs are not linked any devices.

        I download the linux-stable kernel as the document <tizen-ivi-m2-kernel-ltsi-linux-support-package-atom-e3800-gsg.pdf> described. Made and updated the linux kernel.

[root@localhost /]# uname -a

Linux localhost.localdomain 3.10.28-03142014-ltsi+ #2 SMP Fri Aug 4 16:44:39 CST 2017 x86_64 x86_64 x86_64 GNU/Linux

 

    When I input lspci command, I got the message like follows. I can not get the information of  SIO( BUS:0, Device:24, Fun:0~7, DeviceID: 0F40~0F47) from PCI. I wondered whether this is right or not?

    Who can  tell me where and how to set the Baytrail Board's I2c clock?
