[PATCH v2 4/8] phy: move phy-qcom-snps-eusb2 out of its vendor sub-directory

Ivaylo Ivanov
2025-02-23T12:22:37Z

As Samsung is using the same Synopsys eUSB2 IP in Exynos2200, albeit
with a different register layout, it only makes sense to implement
support for that in the existing eUSB2 driver.

To make room for new non-qcom SoCs, do the following:
1. Move phy-qcom-snps-eusb2.c to phy-snps-eusb2.c
2. Rename all qcom_snps_eusb2 functions and structs to snps_eusb2_phy
3. Add a prefix to the qcom-specific register offset definitions
4. Make a generic phy_ops init that sets up power before the SoC-specific
eUSB2 IP init
5. Introduce a driver data structure with init function and clocks
