Subject: [RFC v1 08/11] clk: qcom: Add video clock controller driver for SM8350
Date: Wed, 16 Jun 2021 16:11:04 +0200	[thread overview]
Message-ID: <20210616141107.291430-9-robert.foss@linaro.org> (raw)
In-Reply-To: <20210616141107.291430-1-robert.foss@linaro.org>

Add support for the video clock controller found on SM8350 based devices.

Derived from the downstream driver.
