I assume these are dependent on the board. Please elaborate on your
goal, that means what I2C driver do you need, and what board do you
work on, and give all the necessary details, like what commit hash you
use.

Not able to compile drivers

[chinmoy ghosh]

Thanks for reply.

Requirement :
I am working for Intel Apollo Lake SOC.
I need to enable a power chip which sits on I2c bus  and reset the chip via
gpio pin .So i need to write a slave driver to access the chip.

Static Analysis by me  :
Before that , i2c master should be there .  I feel lpss_i2c.c can help the
same.
I called the lpss_i2c_init function from
external/coreboot/payloads/libpayload/arch/x86/main.c and compiling with
libpayload.a .
let me know if i am right upto this ?. if it is then following questions
are :
1) how to access  GPIO register to ser one or zero
2) how to do i2c slave write for that chip ? any api for that ?

Regards
Chinmoy
