The majority of PHY drivers are PHY providers (obviously).

Some are providers *and* consumers (phy-meson-axg-mipi-dphy,
phy-meson-axg-pcie). These are the Amlogic AXG SoCs, which split the
physical layer into two chained PHYs: the digital layer and the analog
layer. The DSI or PCIe controller interacts only with the digital PHY,
presumably for simplicity.

The rest of PHY drivers which include <linux/phy/phy.h> do so because
they call phy_set_bus_width(), a consumer function.

Conflicts in drivers/phy/canaan/phy-k230-usb.c with commit 8787fa1da603
("phy: usb: Add driver for Canaan K230 USB 2.0 PHY").
Conflicts in drivers/phy/eswin/phy-eic7700-sata.c with commit
67ee9ccaa34a ("phy: eswin: Create eswin directory and add EIC7700 SATA
PHY driver")

Both drivers are newly added in linux-phy/next and not present in
v7.0-rc1. The recommendation is to drop the changes in this patch and
readd them when merging into linux-phy/next.

v2->v3: add conflict resolution details
v1->v2: split in two parts to pass through linux-phy mailing list
