SM8150 and SC8180X are close relatives. Reuse sc8180x data to support
USB+DP combo PHY on SM8150 platform.

I'm not sure this is right. Downstream reuses SA8195 USB seq.

The upstream driver uses sm8150 data for sc8180x. So even if sc8180x
data is not correct for sc8180x, it is definitely the one that we
should use for sm8150:

static const struct qmp_phy_cfg sc8180x_usb3dpphy_cfg = {
        .serdes_tbl             = sm8150_usb3_serdes_tbl,
        .serdes_tbl_num         = ARRAY_SIZE(sm8150_usb3_serdes_tbl),
        .tx_tbl                 = sm8150_usb3_tx_tbl,
        .tx_tbl_num             = ARRAY_SIZE(sm8150_usb3_tx_tbl),
        .rx_tbl                 = sm8150_usb3_rx_tbl,
        .rx_tbl_num             = ARRAY_SIZE(sm8150_usb3_rx_tbl),
        .pcs_tbl                = sm8150_usb3_pcs_tbl,
        .pcs_tbl_num            = ARRAY_SIZE(sm8150_usb3_pcs_tbl),
        .pcs_usb_tbl            = sm8150_usb3_pcs_usb_tbl,
        .pcs_usb_tbl_num        = ARRAY_SIZE(sm8150_usb3_pcs_usb_tbl),

        .dp_serdes_tbl          = qmp_v4_dp_serdes_tbl,
        .dp_serdes_tbl_num      = ARRAY_SIZE(qmp_v4_dp_serdes_tbl),
        .dp_tx_tbl              = qmp_v4_dp_tx_tbl,
        .dp_tx_tbl_num          = ARRAY_SIZE(qmp_v4_dp_tx_tbl),

Right sorry, this patch adds support for 81*5*0. I wanted to point out
that 8180 has a different set of init commands and one of them is probably
incorrect.

FWIW, DP works on my sc8180x devices. (But perhaps still not correct?)
