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.

2017-06-30rx6110sa: Add a software reset sequence in case of power lossWerner Zeh
According to the datasheet the RTC needs a power rising slope of no more than 100µs/V to ensure a correct power-on reset. If the mainboard that hosts the RTC cannot guarantee this, a software reset sequence is needed in the case where the battery was drained completely. As the rising slope of the power supply depends on so many parameters and is highly mainboard specific, refactor the initialization code to perform a software reset every time a power loss event is recognized by the RTC.

2017-06-09rx6110sa: Add more chip configuration options to chipWerner Zeh
The RTC RX6110SA has several configuration options which might be interesting to set. To make this setup independent of the driver itself but let it still be configurable on mainboard level, add more configuration options to the chip driver.

2017-05-11drivers/i2c: Add new driver for RTC type RX6110 SAMario Scheithauer
This driver enables the usage of the external RTC chip RX6110 SA (http://www5.epsondevice.com/en/products/i2c/rx6110sab.html) which is connected to the I2C bus. The I2C address of this device is fixed. One can change parameters in the device tree so that the used setup can be adapted to match the configuration of the device on the mainboard.
