Add the missing the description of the PHY-provider child node which was ignored when converting to DT schema. Fixes: ccf51c1c ("dt-bindings: phy: qcom,qmp: Convert QMP PHY bindings to yaml") Reviewed-by:

Johan Hovold authored
The QMP PHY DT schema is getting unwieldy. Break out the PCIe PHY binding in a separate file. Add an example node based on a cleaned up version of sm8250.dtsi. Reviewed-by:

The QMP PHY DT schema is getting unwieldy. Break out the odd-bird msm8996-qmp-pcie-phy which is the only QMP PHY that uses separate "per-lane" nodes. Add an example node based on a cleaned up version of msm8996.dtsi. Reviewed-by:

Clean up the remaining descriptions by using uppercase "PHY" consistently and dropping redundant information from the register descriptions. Acked-by:

The QMP PHY wrapper node is not a clock provider so drop the bogus '#clock-cells' property that was added when converting to DT schema. Fixes: ccf51c1c ("dt-bindings: phy: qcom,qmp: Convert QMP PHY bindings to yaml") Reviewed-by:

Follow the advice of the below link and prefer 'strscpy' in this subsystem. Conversion is 1:1 because the return value is not used. Generated by a coccinelle script. Link: https://lore.kernel.org/r/CAHk-=wgfRnXz0W3D37d01q3JFkr_i_uTL=V6A6G1oUZcprmknw@mail.gmail.com/Signed-off-by:

The single difference between returning 0 and returning an error code in a platform remove callback is that in the latter case the platform core emits a warning about the error being ignored. If reset_control_assert() fails there is already a warning, so suppress the more generic (and less helpful) by returning 0 in tegra_xusb_padctl_remove(). This is a preparation for making platform remove callbacks return void. Signed-off-by:

Bjorn Andersson authored
The eDP phy can be used to drive either eDP or DP output, with some minor variations in some of the configuration and seemingly a need for implementing swing and pre_emphasis calibration. Introduce a config object, indicating if the phy is operating in eDP or DP mode and swing/pre-emphasis calibration to support this. Signed-off-by:

For J7200-SR2.0 and AM64 we don't model Common refclock divider as a clock divider as the divisor rate is fixed based on operating reference clock frequency. We just program the recommended value into the register. This simplifies the device tree and implementation a lot. Signed-off-by:
