2021-01-23soc/intel/apl: drop LPC pad configuration codeMichael Niewöhner
Drop LPC pad configuration code since all boards now do pad configuration on their own. The comment about LPC_CLKRUNB when using eSPI is moved to `Documentation/getting_started/gpio.md`.

2020-07-26soc/intel/common/gpio_defs: Remove PAD_CFG_NF_BUF_TRIGMaxim Polyakov
This macro is not correct because the RX Level/Edge Configuration (trig) and the GPIO Tx/Rx Buffer Disable (bufdis) fields in DW0 register do not affect on the pad in the native function mode.

2020-01-18documentation: Add documentation on setting up mainboard GPIOsTim Wawrzynczak
The new documentation describes typical ways that mainboards will set up their GPIOs, as well as the distinction between "early" and "normal" GPIOs. It also describes the typical properties that GPIO configuration will cover.
