2019-10-22AUTHORS: Move src/drivers/[a*-i*] copyrights into AUTHORS fileMartin Roth
As discussed on the mailing list and voted upon, the coreboot project is going to move the majority of copyrights out of the headers and into an AUTHORS file. This will happen a bit at a time, as we'll be unifying license headers at the same time. Updated Authors file is in a separate commit.

2018-02-15drivers/i2c: Add chip driver for I/O expander PCA9538Werner Zeh
The chip PCA9538 is a 8 bit I/O expander connected to the systems I2C bus. Add a chip driver to support this chip. Beside the pure chip driver two interface functions are provided to read the state of the pins and write output values to the pins. As the slave address of this chip is hardware configurable the function pca9538_get_dev() is used to get the right slave address. This function needs to be implemented in mainboard code if one needs to use the interface functions to read and write I/O state.
