    Hi

    These are not the drivers I am looking for.

    I am asking the i2c kernel/platform driver to communicate between bq24195 and Host controller.Right now we have in the internet the driver for bq24190.can you please tell me whther we can use this driver for bq24195.

    I have attached the file in this mail.There is no documentaion availabale for this driver code.Is it possible by you to explain the working of this attached driver file.

     

    Best Regards

    Hello Anand,

    Looking through the I2C registers the BQ24190 and the BQ24195 are very similar with the exception of the JEITA elements seen in the BQ24190 REG05 & REG07 and the IR compensation seen in REG06.

    Outside of these differences that fact that the two devices share an EVM and the GUI it stands to reason that if the Linux driver you linked in your post supports the 190 that with a little modification it could fit the 195.

    To adjust the driver you would have to go through the register masks an ensure that the y correspond with the 195 and then at any point where the register settings are different between the 190 and the 195 as seen in their datasheets you would modify the REG defines.

    With these areas of difference highlighted you code search the rest of the driver for references to REG where the devices differ and adjust to accommodate the 195.
