phy: qcom: qmp-ufs: Fix SM8650 PCS table for Gear 4

2026-02-27T15:16:57+00:00

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.

phy: qcom: edp: Fix NULL pointer dereference for phy v6 (x1e80100)

2026-01-14T13:37:30+00:00

For Glymur SoC support, the com_clk_fwd_cfg callback was added, and a stub implementation was added for the v4 of the hardware. However it was omitted for the v6, causing a NULL pointer dereference oops on Hamoa/Purwa (X1E/X1P) SoC devices. Fix by adding the appropriate stub.

The Qualcomm Glymur platform has the new v8 version of the eDP/DP PHY. So rework the driver to support this new version and add the platform specific configuration data. While at it, add the rest of the AUX_CFG reset values for the v4 and v5 platforms, which makes the handling of the platforms specific array cleaner, as they are single sized now.

phy: qcom: edp: Fix the DP_PHY_AUX_CFG registers count

2026-01-01T11:03:57+00:00

On all platforms supported by this driver, there are 13 DP_PHY_AUX_CFGx registers. This hasn't been an issue so far on currently supported platforms, because the init sequence never spanned beyond DP_PHY_AUX_CFG9. However, on the new upcoming Glymur platform, these are updated along with the rest of the init sequence. So update the size of the array holding the config to 13.

phy: qcom: edp: Make the number of clocks flexible

2026-01-01T11:02:59+00:00

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.
