Move resets to qmp_phy_cfg for per-PHY customization. Keep legacy DT
path on the old hardcoded list; non-legacy path uses cfg->reset_list.

This is unused in this patch. It should go to the patch adding QCS615 DP
PHY compatible and the rest of the config data.

The original reset list only works for USB-only PHYs. USB3DP PHYs need different reset names like "dp_phy", so they use a separate list. Moving resets to qmp_phy_cfg enables per-PHY config without special-case logic in DT parsing. I will update commit msg with issue description. Or do you suggest using (offs->dp_serdes != 0) to choose the reset list instead using new attributes? >> Signed-off-by: Xiangxu Yin <xiangxu.yin@oss.qualcomm.com> >> --- >> drivers/phy/qualcomm/phy-qcom-qmp-usbc.c | 18 +++++++++++++++--- >> 1 file changed, 15 insertions(+), 3 deletions(-) >>
