Subject: [PATCH 0/3] phy: qcom: edp: Add support for DT phy mode configuration
Date: Tue, 19 Dec 2023 22:55:21 +0200 [thread overview]
Message-ID: <20231219-x1e80100-phy-edp-compatible-refactor-v1-0-f9e77752953d@linaro.org> (raw)
Until now, all platform that supported both eDP and DP had different
compatibles for each mode. Using different compatibles for basically
the same IP block but for a different configuration is bad way all
around. There is a new compute platform from Qualcomm that supports
both eDP and DP with the same PHY. So instead of following the old
method, we should allow the mode to be configured from devicetree.
There has been an off-list discussion on what would be the right way
to pass on the PHY mode information to the driver and it has been
concluded that phy-cells is the way to go. This means that basically
the controller will pass another value (that is, the PHY type) to
its 'phys' DT property.
For this, we need both the bindings value and the PHY mode value to be
added as well.
The controller part will follow shortly. But for now, lets see where
this is going.
There has been another attempt at this here:
https://lore.kernel.org/all/20231122-phy-qualcomm-edp-x1e80100-v3-3-576fc4e9559d@linaro.org/
Compared to that version, this one uses the phy-cells method and drops
the X1E80100 support. The X1E80100 support will be a separate patchset.
