From 016ef9e9bc36c60101b707a8c1c926e78350befa Mon Sep 17 00:00:00 2001 From: Nico Huber Date: Tue, 19 Sep 2017 14:13:34 +0200 Subject: ec/kontron: Add support for Kontron kempld A programmable logic device used by Kontron as EC on their COM express modules. The name `kempld` is taken from Linux kernel sources, as is the I2C driver. The meaning of the acronym is unclear, probably: Kontron Embedded Module PLD.
