[PATCH v4 0/2] Add edp reference clock for lemans

[PATCH v4 0/2] Add edp reference clock for lemans

[Ritesh Kumar]

On lemans chipset, edp reference clock is being voted by ufs mem phy
(ufs_mem_phy: phy@1d87000). But after commit 77d2fa54a945
("scsi: ufs: qcom : Refactor phy_power_on/off calls") edp reference
clock is getting turned off, leading to below phy poweron failure on
lemans edp phy.

[PATCH v4 1/2] dt-bindings: phy: qcom-edp: Add reference clock for sa8775p eDP PHY

[Ritesh Kumar]

The initial sa8775p eDP PHY binding contribution missed adding support for
voting on the eDP reference clock. This went unnoticed because the UFS PHY
driver happened to enable the same clock.

After commit 77d2fa54a945 ("scsi: ufs: qcom : Refactor phy_power_on/off
calls"), the eDP reference clock is no longer kept enabled, which results
in the following PHY power-on failure:

phy phy-aec2a00.phy.10: phy poweron failed --> -110

To fix this, explicit voting for the eDP reference clock is required.
This patch adds the eDP reference clock for sa8775p eDP PHY and updates
the corresponding example node.

[PATCH v4 2/2] arm64: dts: qcom: lemans: Add eDP ref clock for eDP PHYs

[Ritesh Kumar]

The eDP PHY nodes on lemans were missing the reference clock voting.
This initially went unnoticed because the clock was implicitly enabled
by the UFS PHY driver, and the eDP PHY happened to rely on that.

After commit 77d2fa54a945 ("scsi: ufs: qcom : Refactor phy_power_on/off
calls"), the UFS driver no longer keeps the reference clock enabled.
As a result, the eDP PHY fails to power on.

To fix this, add eDP reference clock for eDP PHYs on lemans chipset
ensuring reference clock is enabled.

Is there any reason why you didn't follow up on this patch Ritesh?

It's been two months now, if you want your patches to be merged please
show that - ask the maintainer for a status update, ask a colleague to
send a reviewed-by...

Perhaps the maintainer lost track of your change?

Perhaps it's not clear that the change "need" an Ack from e.g. Dmitry
and then it should be merged by Vinod? Because you're changing two
different subsystems but leave it up to the maintainers to figure out
how to deal with this...


Either way, show that you want this to be merged, don't just wait until
the situation resolves itself.
