This series enables USB on Qualcomm SDM845 platforms and lays the foundation for future SoCs as well.
It introduces two new high-speed PHY drivers, one for SDM845 and one for an upcoming platform. The SDM845 clock driver gains support for configuring the USB clocks, and the GPIO driver is updated to use .set_flags which fixes a strange bug where GPIOs would also be configured as input.
Support for super-speed USB modes is not currently available, however configuring the device to be high-speed only requires modifications to DT.
To improve compatibility with upstream DT, we switch Qualcomm platforms over to OF_LIVE and apply fixups to the tree to remove references to the super-speed phy, as well as configure the Qualcomm glue for high-speed only mode.
The db845c requires a vbus-supply to be hooked up for its usb type-A port. A U-Boot dtsi file is added to configure this.
With these patches, it is now also possible to run U-Boot on some SDM845 phones like the OnePlus 6 using a dtb from Linux, and access the U-Boot shell via the CDC ACM USB serial gadget.
This series depends on the ("Qualcomm DWC3 USB support") series [1], as well as Volodymyrs patches enabling power domain support [2]. A feature branch based on qcom-next with the necessary dependencies for testing the Dragonboard845c can be found at [3].

--- Changes in v4: - Fix defconfig. - Mark db845c vbus regulator always-on to fix a bug in Linux. - Add a timer in qcom_of_fixup_nodes() so the boot time impact can be easily measured. - Drop unused macros from femto v2 phy, general cleanup, remove custom set/clrbits impl. - Rename "7nm" phy driver to "femto-v2" to match Linux, also fix copyright. - Use set/clrbits() in qusb2 phy driver. - Link to v3: https://lore.kernel.org/r/20240319-b4-qcom-livetree-v3-0-e1b38d9b4fa4@linaro...
Changes in v3: - Add back missing gadget options to qcom_defconfig (thanks Neil) - Link to v2: https://lore.kernel.org/r/20240315-b4-qcom-livetree-v2-0-ab635774b2dc@linaro...
Changes in v2: - Fix incorrect order of NULL/0 parameters to of_write_prob() in fixup_qcom_dwc3() - Move fixup_usb_nodes() to a separate file in preparation for future additions. - Add missing break to switch case in sdm845_clk_enable() - Remove rogue return statement in msm_gpio_set_flags() - Rebase on Volodymyrs power domain patches. - Link to v1: https://lore.kernel.org/r/20240131-b4-qcom-livetree-v1-0-4071c0787db0@linaro...
