Subject: [PATCH 5/8] arm64: dts: hisilicon: hi3670.dtsi: add I2C settings
Date: Mon, 16 Nov 2020 13:59:31 +0100 [thread overview]
Message-ID: <39b0576b5b8725584830d187142fe45120f6f69c.1605530560.git.mchehab+huawei@kernel.org> (raw)
In-Reply-To: <cover.1605530560.git.mchehab+huawei@kernel.org>
The I2C buses are not declared at the device tree. As this will
be needed by further patches, add them, keeping all in
disabled state. Per-board settings can override it.
