I tested it on the sa8775p. AFAICT there's no noticeable change before/after the patch series: lsusb and dmesg output are the same. USB is still working properly. I don't know what those PCS_USB registers do exactly on the qmp PHY and I don't have access to the PHY datasheet, so it's hard for me to tell the impact of them being initialized vs not. v1 -> v2: - Don't fallback to pcs for PCS_USB initialization (Dmitry Baryshkov) Adrien Thierry (2): phy: qcom-qmp-usb: initialize PCS_USB registers phy: qcom-qmp-usb: split PCS_USB init table for sc8280xp and sa8775p drivers/phy/qualcomm/phy-qcom-qmp-usb.c | 24 +++++++++++++++++++----- 1 file changed, 19 insertions(+), 5 deletions(-)
