Piotr Zięcik aa363178d3 drivers: i2c_bitbang: Do not use CONFIG_SYS_CLOCK_HW_CYCLES_PER_SEC
On some SoCs the frequency of the system clock is obtained at run time
as the exact configuration of the hardware is not known at compile time.
On such platforms using CONFIG_SYS_CLOCK_HW_CYCLES_PER_SEC define
directly introduces timing errors.

This commit replaces CONFIG_SYS_CLOCK_HW_CYCLES_PER_SEC by the call to
inline function sys_clock_hw_cycles_per_sec() which always returns
correct frequency of the system clock.

Jon Medhurst 0818564753 i2c: bitbang: Add library for software driven I2C
This library implements the I2C single master protocol in software.
It supports the Standard-mode and Fast-mode speeds and doesn't support
optional protocol feature like 10-bit addresses or clock stretching.
