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 ?
