STRUCT I2C_TIMINGS(9) I2C and SMBus Subsystem STRUCT I2C_TIMINGS(9)

NAME

struct_i2c_timings - I2C timing information

SYNOPSIS

struct i2c_timings {


  u32 bus_freq_hz;


  u32 scl_rise_ns;


  u32 scl_fall_ns;


  u32 scl_int_delay_ns;


  u32 sda_fall_ns;
};

MEMBERS

bus_freq_hz

the bus frequency in Hz

scl_rise_ns

time SCL signal takes to rise in ns; t(r) in the I2C specification

scl_fall_ns

time SCL signal takes to fall in ns; t(f) in the I2C specification

scl_int_delay_ns

time IP core additionally needs to setup SCL in ns

sda_fall_ns

time SDA signal takes to fall in ns; t(f) in the I2C specification
