Subject: [PATCH v3 03/15] arm64: dts: qcom: sdm845: Add the missing clocks on the dispcc
Date: Thu, 30 Jan 2020 13:12:19 -0800	[thread overview]
Message-ID: <20200130131220.v3.3.Ie80fa74e1774f4317d80d70d30ef4b78f16cc8df@changeid> (raw)
In-Reply-To: <20200130211231.224656-1-dianders@chromium.org>

We're transitioning over to requiring the Qualcomm Display Clock
Controller to specify all the input clocks.  Let's add them for
sdm845.

NOTES:
- Until the Linux driver for sdm845's dispcc is updated, these clocks
  will not actually be used in Linux.  It will continue to use global
  clock names to match things up.
- Although the clocks from the DP PHY are required, the DP PHY isn't
  represented in the dts yet.  Apparently the magic for this is just
  to use <0>.

Signed-off-by: Douglas Anderson <dianders@chromium.org>
---

Changes in v3:
- Newly discovered gcc_disp_gpll0_div_clk_src added.
- Unlike in v2, use internal name instead of purist name.

Changes in v2:
- Patch ("arm64: dts: qcom: sdm845: Add...dispcc") new for v2.
