The TUSB1211 is a ULPI PHY. Linux has a built-in driver for ULPI PHYs.

Recently, a driver for the TI TUSB1210 ULPI PHY was posted:

TUSB1210 ULPI PHY has vendor specific register for eye diagram tuning. On some platforms the system firmware has set optimized value to it. In order to not loose the optimized value, the driver stores it during probe and restores it every time the PHY is powered back on.

It is not yet part of the mainline kernel, and you probably do not need it.

Thank you for your comment.
I understood Linux has a built-in driver for ULPI PHYs.

How about Android driver for TUSB1211?

Android uses the Linux kernel, but you have to check whether your Android version uses kernel 3.15 or later.

If not, you might need to backport the patch that adds the TUSB1210 product ID, or the entire ULPI driver.
(I don't know if the TUSB1211 uses the same product ID as the TUSB1210; the datasheet does not tell.)

Then no standard kernel will work out-of-the-box; you need to add an entry for that ID.
