From 6b4a1ab82a49c9288f7964b9c1836729dcc340a6 Mon Sep 17 00:00:00 2001 From: Werner Zeh Date: Mon, 7 Nov 2022 07:46:49 +0100 Subject: drivers/i2c/designware: Add 100 MHz controller base clock There are SoCs (for instance Intel Elkhart Lake) that do use 100 MHz as the base clock for I2C controllers. To support them properly add a frequency setting for 100 MHz to the designware I2C controller driver.
