Subject: [PATCH v3 2/2] clk: qcom: gcc-sdm660: Remove transient global "xo" clock
Date: Sat, 11 Sep 2021 15:19:21 +0200	[thread overview]
Message-ID: <20210911131922.387964-3-marijn.suijten@somainline.org> (raw)
In-Reply-To: <20210911131922.387964-1-marijn.suijten@somainline.org>

The DSI PHY/PLL was relying on a global "xo" clock to be found, but the
real clock is named "xo_board" in the DT.  The standard nowadays is to
never use global clock names anymore but require the firmware (DT) to
provide every clock binding explicitly with .fw_name.  The DSI PLLs have
since been converted to this mechanism (specifically 14nm for SDM660)
and this transient clock can now be removed.

This issue was originally discovered in:
https://lore.kernel.org/linux-arm-msm/386db1a6-a1cd-3c7d-a88e-dc83f8a1be96@somainline.org/
and prevented the removal of "xo" at that time.
