Subject: [PATCH v4 15/15] arm64: dts: sc7180: Add clock controller nodes
Date: Mon, 3 Feb 2020 10:31:48 -0800 [thread overview]
Message-ID: <20200203103049.v4.15.I1a4b93fb005791e29a9dcf288fc8bd459a555a59@changeid> (raw)
In-Reply-To: <20200203183149.73842-1-dianders@chromium.org>
From: Taniya Das <tdas@codeaurora.org>
Add the display, video & graphics clock controller nodes supported on
SC7180.
NOTE: the dispcc needs input clocks from various PHYs that aren't in
the device tree yet. For now we'll leave these stubbed out with <0>,
which is apparently the magic way to do this. These clocks aren't
really "optional" and this stubbing out method is apparently the best
way to handle it.

Changes in v4: None
Changes in v3:
- Added videocc include file.
- Unlike in v2, use internal name instead of purist name.
Changes in v2:
- Added includes
- Changed various parent names to match bindings / driver
