phy: ti: phy-j721e-wiz: fix usxgmii configuration

2024-10-17T14:53:02Z

Commit b64a85fb8f53 ("phy: ti: phy-j721e-wiz.c: Add usxgmii support in wiz driver") added support for USXGMII mode. In doing so, P0_REFCLK_SEL was set to "pcs_mac_clk_divx1_ln_0" (0x3) and P0_STANDARD_MODE was set to LANE_MODE_GEN1, which results in a data rate of 5.15625 Gbps. However, since the USXGMII mode can support up to 10.3125 Gbps data rate, the aforementioned fields should be set to "pcs_mac_clk_divx0_ln_0" (0x2) and LANE_MODE_GEN2 respectively. The signal corresponding to the USXGMII lane of the SERDES has been measured as 5 Gbps without the change and 10 Gbps with the change. Hence, fix the configuration accordingly to support USXGMII up to 10G.

phy: starfive: jh7110-usb: Fix link configuration to controller

2024-10-17T14:49:44Z

In order to connect the USB 2.0 PHY to its controller, we also need to set "u0_pdrstn_split_sw_usbpipe_plugen" [1]. Some downstream U-Boot versions did that, but upstream firmware does not, and the kernel must not rely on such behavior anyway. Failing to set this left the USB gadget port invisible to connected hosts behind.

phy: qcom: qmp-combo: move driver data initialisation earlier

2024-10-17T13:04:16Z

Commit 44aff8e31080 ("phy: qcom-qmp-combo: clean up probe initialisation") removed most users of the platform device driver data, but mistakenly also removed the initialisation despite the data still being used in the runtime PM callbacks. The initialisation was soon after restored by commit 83a0bbe39b17 ("phy: qcom-qmp-combo: add support for updated sc8280xp binding") but now happens slightly later during probe. This should not cause any trouble currently as runtime PM needs to be enabled manually through sysfs and the platform device would not be suspended before the PHY has been registered anyway. Move the driver data initialisation to avoid a NULL-pointer dereference on runtime suspend if runtime PM is ever enabled by default in this driver.
