[PATCH 0/2] Add Exynos5515 USB PHY support

[Aiden Isik via B4 Relay]

Hi there,

This patchset adds support for the Exynos5515 USB PHY.

The PHY supports High-Speed (UTMI+), and also appears to support
Super-Speed (PIPE3) USB according to Samsung's own code to drive this PHY.
However, none of the Exynos5515 hardware which I am aware of actually
supports Super-Speed, therefore I am unable to test that part, hence PIPE3
support being omitted.

This patchset was tested on a Samsung Galaxy Watch FE using the USB serial
gadget.

This patchset also depends on [1], due to using an
exynos5_usbdrd_phy_drvdata member (.n_phy_cfg) which was introduced to fix
an out-of-bounds access bug.

It also depends on [2] and [3] in that they are the clock and pinctrl
drivers for Exynos5515, and without them this driver cannot talk to the
PHY. It does however build without them. [2] should be close to being
merged into Torvalds' tree, and [3] was just submitted by myself a few
days ago.
