2021-07-16ec/kontron/kempld: Add minimal GPIO driverMaxim Polyakov
The patch adds an interface for configuring GPIOs inside the Kontron CPLD/EC. This allows to statically define the mode for each GPIO pin in devicetree.cb of the motherboard or carrier board. For example: chip ec/kontron/kempld device gpio 0 on register "gpio[0]" = "KEMPLD_GPIO_INPUT" register "gpio[4]" = "KEMPLD_GPIO_OUTPUT_LOW" register "gpio[5]" = "KEMPLD_GPIO_OUTPUT_HIGH" register "gpio[11]" = "KEMPLD_GPIO_DEFAULT" end end In this case, <device gpio 0>, like all other devices, is not a real device inside the EC. These definitions are used to understand the EC resources and systematize configuration options, but if mark this as <off>, the initialization step will be skipped in the driver code. Use KEMPLD_GPIO_DEFAULT or skip it in devicetree.cb to not configure the GPIO and keep the default mode after CPLD reset. This work is based on code from the drivers/gpio/gpio-kempld.c linux driver. Tested on Kontron mAL-10 COMe module [1].

2020-10-11ec/kontron/kempld: add option to configure I2C frequencyMaxim Polyakov
Allows to change the I2C bus frequency by overriding i2c_frequency option from the board devicetree. Thus, the I2C controller can use Fast-mode (Fm), with a bit rate up to 400 kbit/s and Fast-mode Plus (Fm+), with a bit rate up to 1 Mbit/s [1]. Tested on Kontron mAL10 COMe module with T10-TNI carrierboard [2]. [1] I2C-bus specification and user manual, doc #UM10204, Rev. 6, 4 April 2014.

2020-03-17src (minus soc and mainboard): Remove copyright noticesPatrick Georgi
They're listed in AUTHORS and often incorrect anyway, for example: - What's a "Copyright $year-present"? - Which incarnation of Google (Inc, LLC, ...) is the current copyright holder? - People sometimes have their editor auto-add themselves to files even though they only deleted stuff - Or they let the editor automatically update the copyright year, because why not? - Who is the copyright holder "The coreboot project Authors"? - Or "Generated Code"? Sidestep all these issues by simply not putting these notices in individual files, let's list all copyright holders in AUTHORS instead and use the git history to deal with the rest.
