Keep the USB pipe clock working when the phy is in DP-only mode, because the dwc controller still needs it for USB 2.0 over the same Type-C port.

2026-05-10phy: qcom-qmp-ufs: Fix kaanapali PHY PLL lock failure after SM8650 G4 fixNitin Rawat
Commit 81af9e40e2e4 ("phy: qcom: qmp-ufs: Fix SM8650 PCS table for Gear 4") moved QPHY_V6_PCS_UFS_PLL_CNTL register configuration from the shared sm8650_ufsphy_g5_pcs table to the SM8650-specific sm8650_ufsphy_pcs base table to fix Gear 4 operation on SM8650. However, this change inadvertently broke kaanapali and SM8750 SoCs which also rely on the shared sm8650_ufsphy_g5_pcs table for Gear 5 configuration but use their own sm8750_ufsphy_pcs base table. After the change, kaanapali PHYs are left without the required PLL_CNTL = 0x33 setting, causing the PHY PLL to remain at its hardware reset default value, preventing PLL lock and resulting in DME_LINKSTARTUP timeouts. Fix this by adding the missing QPHY_V6_PCS_UFS_PLL_CNTL = 0x33 entry to the sm8750_ufsphy_pcs table, mirroring what the original commit already did for sm8650_ufsphy_pcs.

Commit 81791c45c8e0 ("phy: qcom: qmp-usbc: Add QCS615 USB/DP PHY config and DP mode support") chose to name QCS615 DP PHY variables/functions with qmp_v2 prefix, by assuming that QMP PHY registers are versioned as a whole. However, the reality is that the registers are versioned in sub-modules like QSERDES COM and QSERDES TXRX respectively, e.g. QCS615 DP PHY has registers of QSERDES COM v2 and QSERDES TXRX v3. Thus it may cause confusion that qmp_v2_xxx table and functions access QSERDES TXRX v3 registers. Rename QCS615 DP PHY variables and functions to be prefixed by qcs615 instead of qmp_v2. This better aligns with how the driver names USB3 PHY variables for QCM2290 etc. Signed-off-by: Shawn Guo <shengchao.guo@oss.qualcomm.com> Link: https://patch.msgid.link/20260314051325.198137-5-shengchao.guo@oss.qualcomm.com Signed-off-by: Vinod Koul <vkoul@kernel.org>

The eDP PHY supports both eDP/DP modes, each requiring a different swing/pre-emphasis table. However, the driver currently uses a fixed static table for eDP programming rather than selecting the appropriate table based on the current mode. Add separate tables for eDP and DP modes, and select the appropriate table dynamically based on the current mode. Glymur's DP mode table differs from the other platforms, add a dedicated table for it. This also fixes the table mismatch for X1E80100 (eDP) and SA8775P (DP).

As established in the previous commit, using SPEED_1000 and SPEED_2500 does not make sense for a SerDes due to the PCS encoding that is used over the SerDes link, which inflates the data rate at the SerDes. Thus, the use of these constants in a SerDes driver is incorrect. Since qcom-sgmii-eth no longer implements phy_set_speed(), but instead uses the PHY interface mode passed via the .set_mode() method, convert the driver to use the PHY interface mode internally to decide whether to configure the SerDes for 1.25Gbps or 3.125Gbps mode.

Remove support for this method. Using the MAC speed for the SerDes is never correct due to the PCS encoding. For SGMII and 2500BASE-X, the PCS uses 8B10B encoding, and so: MAC rate * PCS output bits / PCS input bits = SerDes rate 1000M * 10 / 8 = 1250M 2500M * 10 / 8 = 3125M Tested-by: Mohd Ayaan Anwar <mohd.anwar@oss.qualcomm.com> Acked-by: Vinod Koul <vkoul@kernel.org> Reviewed-by: Vladimir Oltean <vladimir.oltean@nxp.com> Signed-off-by: Russell King (Oracle) <rmk+kernel@armlinux.org.uk> Link: https://patch.msgid.link/E1vxS49-0000000BQXa-3Zcg@rmk-PC.armlinux.org.uk Signed-off-by: Jakub Kicinski <kuba@kernel.org>

2026-02-27phy: qcom: qmp-ufs: Fix SM8650 PCS table for Gear 4Abel Vesa
According to internal documentation, on SM8650, when the PHY is configured in Gear 4, the QPHY_V6_PCS_UFS_PLL_CNTL register needs to have the same value as for Gear 5. At the moment, there is no board that comes with a UFS 3.x device, so this issue doesn't show up, but with the new Eliza SoC, which uses the same init sequence as SM8650, on the MTP board, the link startup fails with the current Gear 4 PCS table. So fix that by moving the entry into the PCS generic table instead, while keeping the value from Gear 5 configuration.

The driver currently sets bit 0 of USB_PHY_CFG1 (PLL_EN) during PHY initialization. According to the M31 EUSB2 PHY hardware documentation, this bit is intended only for test/debug scenarios and does not control mission mode operation. Keeping PLL_EN asserted causes the PHY to draw additional current during USB bus suspend. Clearing this bit results in lower suspend power consumption without affecting normal operation. Update the driver to leave PLL_EN cleared as recommended by the hardware documentation.

2026-01-01phy: qcom: edp: Make the number of clocks flexibleAbel Vesa
On X Elite, the DP PHY needs another clock called ref, while all other platforms do not. The current X Elite devices supported upstream work fine without this clock, because the boot firmware leaves this clock enabled. But we should not rely on that. Also, even though this change breaks the ABI, it is needed in order to make the driver disables this clock along with the other ones, for a proper bring-down of the entire PHY. So in order to handle these clocks on different platforms, make the driver get all the clocks regardless of how many there are provided.
