Subject: [PATCH AUTOSEL 5.4 16/33] mfd: intel-lpss: Add default I2C device properties for Gemini Lake
Date: Thu, 23 Jan 2020 20:16:51 -0500	[thread overview]
Message-ID: <20200124011708.18232-16-sashal@kernel.org> (raw)
In-Reply-To: <20200124011708.18232-1-sashal@kernel.org>

From: Jarkko Nikula <jarkko.nikula@linux.intel.com>

[ Upstream commit 3f31bc67e4dc6a555341dffefe328ddd58e8b431 ]

It turned out Intel Gemini Lake doesn't use the same I2C timing
parameters as Broxton.

I got confirmation from the Windows team that Gemini Lake systems should
use updated timing parameters that differ from those used in Broxton
based systems.
