*	Use 7bit I2C/SPI slave addresses in EC	Denis Brockus	2019-07-19	1	-2/+2
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Opt for 7bit slave addresses in EC code. If 8bit is expected by a driver, make it local and show this in the naming. Use __7b, __7bf and __8b as name extensions for i2c/spi addresses used in the EC codebase. __7b indicates a 7bit address by itself. __7bf indicates a 7bit address with optional flags attached. __8b indicates a 8bit address by itself. Allow space for 10bit addresses, even though this is not currently being used by any of our attached devices. These extensions are for verification purposes only and will be removed in the last pass of this ticket. I want to make sure the variable names reflect the type to help eliminate future 7/8/7-flags confusion.

*	driver/max695x: Add 7 segment display driver	Ayushee	2019-05-02	1	-0/+44
	Port80 information and power sequencing states can be displayed on the 7-segment so that we can observe its information without connecting a debugger. Adding this CL to initialize and write to the 7-segment display. For port80, 80(data) gets displayed on the seven segment, for the power states, EC(state) gets displayed on the seven segment. The MAX6958/MAX6959 is a compact multiplexed common - cathode display designed to interface microprocessors with seven - segment numerical LED digits or to discrete LEDs via a 2-wire serial interface compatible with SMBusTM and I2C. The 2-wire serial interface uses fixed logic thresholds of 0.8V/2.1V when the display driver is powered from a 5V supply for compatibility with 2.5V and 3.3V systems.
