We have a total 99 non-merge commits going into v5.8 merge window. The majority of the changes are in dwc3 this around (31.7% of all changes). It's composed mostly Thinh's recent updates to get dwc3 to behave correctly with stream transfers. We have also have Roger's for Keystone platforms and Neil's updates for the meson glue layer. Apart from those, we have the usual set of non-critical fixes, new device IDs, spelling fixes all over the place.

2020-05-25phy: amlogic: meson-gxl-usb3: remove code for non-existing PHYMartin Blumenstingl
The registers which are managed by the meson-gxl-usb3 PHY driver are actually "USB control" registers (which are "glue" registers which manage OTG detection and routing of the OTG capable port between the DWC2 peripheral-only controller and the DWC3 host-only controller). Drop the meson-gxl-usb3 PHY driver now that the dwc3-meson-g12a-usb driver supports the USB control registers on GXL and GXM SoCs (these were previously managed by the meson-gxl-usb3 PHY driver).

2020-05-18phy: qcom-qmp: Ensure register indirection arrays initializedBjorn Andersson
It's possible that struct qmp_phy_cfg->regs references an array that is smaller than the possible register lookups that is going to be performed, with the resulting out-of-bounds read resulting in undefined behavior. One such example is when during qcom_qmp_phy_com_init() performs a qphy_setbits() on entry QPHY_PCS_POWER_DOWN_CONTROL (i.e. 17) with msm8996_ufsphy_regs_layout only being 12 entries long. Solve this by inflating all "regs_layout" arrays to ensure that any remaining entries are zero-initialized, as expected by the code.

This patch fixes a regression in 5.7-rc1+ In commit 8fe75cd4cddf ("phy: qcom-qusb2: Add generic QUSB2 V2 PHY support"), the change was made to add "qcom,qusb2-v2-phy" as a generic compat string. However the change also removed the "qcom,sdm845-qusb2-phy" compat string, which is documented in the binding and already in use. This patch re-adds the "qcom,sdm845-qusb2-phy" compat string which allows the driver to continue to work with existing dts entries such as found on the db845c.

2020-04-16phy: tegra: Select USB_COMMON for usb_get_maximum_speed()Thierry Reding
The usb_get_maximum_speed() function is part of the usb-common module, so enable it by selecting the corresponding Kconfig symbol. While at it, also make sure to depend on USB_SUPPORT because USB_PHY requires that. This can lead to Kconfig conflicts if USB_SUPPORT is not enabled while attempting to enable PHY_TEGRA_XUSB.

The phy-gmii-sel can be only auto selected in Kconfig and now the pretty complex Kconfig dependencies are defined for phy-gmii-sel driver, which also need to be updated every time phy-gmii-sel is re-used for any new networking driver. Simplify Kconfig definition for phy-gmii-sel PHY driver - drop all dependencies and from networking drivers and rely on using 'imply PHY_TI_GMII_SEL' in Kconfig definitions for networking drivers instead.
