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.

2026-01-01phy: qcom: edp: Make the number of clocks flexibleAbel Vesa-8/+8
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.

For SuperSpeed USB to work properly, there is a set of HW settings that need to be programmed into the USB blocks within the QMP PHY. Ensure that these settings follow the latest settings mentioned in the HW programming guide. The QMP USB PHY on Glymur is a USB43 based PHY that will have some new ways to define certain registers, such as the replacement of TXA/RXA and TXB/RXB register sets. This was replaced with the LALB register set. There are also some PHY init updates to modify the PCS MISC register space. Without these, the QMP PHY PLL locking fails.

2025-12-23phy: qcom-qusb2: Fix NULL pointer dereference on early suspendLoic Poulain-8/+8
Enabling runtime PM before attaching the QPHY instance as driver data can lead to a NULL pointer dereference in runtime PM callbacks that expect valid driver data. There is a small window where the suspend callback may run after PM runtime enabling and before runtime forbid. This causes a sporadic crash during boot: ``` Unable to handle kernel NULL pointer dereference at virtual address 00000000000000a1 [...] CPU: 0 UID: 0 PID: 11 Comm: kworker/0:1 Not tainted 6.16.7+ #116 PREEMPT Workqueue: pm pm_runtime_work pstate: 20000005 (nzCv daif -PAN -UAO -TCO -DIT -SSBS BTYPE=--) pc : qusb2_phy_runtime_suspend+0x14/0x1e0 [phy_qcom_qusb2] lr : pm_generic_runtime_suspend+0x2c/0x44 [...] ``` Attach the QPHY instance as driver data before enabling runtime PM to prevent NULL pointer dereference in runtime PM callbacks. Reorder pm_runtime_enable() and pm_runtime_forbid() to prevent a short window where an unnecessary runtime suspend can occur. Use the devres-managed version to ensure PM runtime is symmetrically disabled during driver removal for proper cleanup.

2025-09-01phy: qcom: qmp-pcie: Fix PHY initialization when powered down by firmwareStephan Gerhold-6/+19
Commit 0cc22f5a861c ("phy: qcom: qmp-pcie: Add PHY register retention support") added support for using the "no_csr" reset to skip configuration of the PHY if the init sequence was already applied by the boot firmware. The expectation is that the PHY is only turned on/off by using the "no_csr" reset, instead of powering it down and re-programming it after a full reset. The boot firmware on X1E does not fully conform to this expectation: If the PCIe3 link fails to come up (e.g. because no PCIe card is inserted), the firmware powers down the PHY using the QPHY_PCS_POWER_DOWN_CONTROL register. The QPHY_START_CTRL register is kept as-is, so the driver assumes the PHY is already initialized and skips the configuration/power up sequence. The PHY won't come up again without clearing the QPHY_PCS_POWER_DOWN_CONTROL, so eventually initialization fails: qcom-qmp-pcie-phy 1be0000.phy: phy initialization timed-out phy phy-1be0000.phy.0: phy poweron failed --> -110 qcom-pcie 1bd0000.pcie: cannot initialize host qcom-pcie 1bd0000.pcie: probe with driver qcom-pcie failed with error -110 This can be reliably reproduced on the X1E CRD, QCP and Devkit when no card is inserted for PCIe3. Fix this by checking the QPHY_PCS_POWER_DOWN_CONTROL register in addition to QPHY_START_CTRL. If the PHY is powered down with the register, it doesn't conform to the expectations for using the "no_csr" reset, so we fully re-initialize with the normal reset sequence. Also check the register more carefully to ensure all of the bits we expect are actually set. A simple !!(readl()) is not enough, because the PHY might be only partially set up with some of the expected bits set.

2025-09-01phy: qcom-qmp-ufs: Add regulator load voting for UFS QMP PHYNitin Rawat-21/+8
On certain SoCs, power regulators are shared between the QMP UFS PHY and other IP blocks. To ensure proper operation, the regulator framework must be informed of the UFS PHY's load requirements. This is essential because the regulator's operating mode—whether Low Power or High Power—depends on the maximum expected load at any given time, which the regulator driver needs to manage accordingly. To support this, replace devm_regulator_bulk_get() with devm_regulator_bulk_get_const() and inline the qmp_ufs_vreg_init() function. additionally replace the array of regulator names with a bulk regulator data structure, and utilize the init_load_uA field provided by the regulator framework. This ensures that regulator_set_load() is automatically invoked before the first enable operation.

The DisplayPort phy should be left enabled if is still powered on by the DRM DisplayPort controller, so bail out until the DisplayPort PHY is not powered off. The Type-C Mode/SVID only changes on plug/unplug, and USB SAFE states will be set in between of USB-Only, Combo and DisplayPort Only so this will leave enough time to the DRM DisplayPort controller to turn of the DisplayPort PHY.
