phy: qcom: qmp-pcie: drop bogus x1e80100 qref supplies

2024-10-17T14:42:05Z

The PCIe PHYs on x1e80100 do not a have a qref supply so stop requesting one. This also avoids the follow warning at boot: qcom-qmp-pcie-phy 1bfc000.phy: supply vdda-qref not found, using dummy regulator Fixes: 9dab00ee9544 ("phy: qcom: qmp-pcie: Add Gen4 4-lanes mode for X1E80100") Fixes: 606060ce8fd0 ("phy: qcom-qmp-pcie: Add support for X1E80100 g3x2 and g4x2 PCIE") Cc: Abel Vesa Signed-off-by: Johan Hovold Reviewed-by: Neil Armstrong Link: https://lore.kernel.org/r/20241015121406.15033-1-johan+linaro@kernel.org Signed-off-by: Vinod Koul

phy: qcom: qmp-combo: move driver data initialisation earlier

2024-10-17T13:04:16Z

Commit 44aff8e31080 ("phy: qcom-qmp-combo: clean up probe initialisation") removed most users of the platform device driver data, but mistakenly also removed the initialisation despite the data still being used in the runtime PM callbacks. The initialisation was soon after restored by commit 83a0bbe39b17 ("phy: qcom-qmp-combo: add support for updated sc8280xp binding") but now happens slightly later during probe. This should not cause any trouble currently as runtime PM needs to be enabled manually through sysfs and the platform device would not be suspended before the PHY has been registered anyway. Move the driver data initialisation to avoid a NULL-pointer dereference on runtime suspend if runtime PM is ever enabled by default in this driver.

phy: qcom: qmp-usbc: fix NULL-deref on runtime suspend

2024-10-17T13:03:46Z

Commit 413db06c05e7 ("phy: qcom-qmp-usb: clean up probe initialisation") removed most users of the platform device driver data from the qcom-qmp-usb driver, but mistakenly also removed the initialisation despite the data still being used in the runtime PM callbacks. This bug was later reproduced when the driver was copied to create the qmp-usbc driver. Restore the driver data initialisation at probe to avoid a NULL-pointer dereference on runtime suspend. Apparently no one uses runtime PM, which currently needs to be enabled manually through sysfs, with these drivers.
