Sorry about this, but I would like to keep devm_ioremap_nocache() here,
because this Renesas R-Car PHY address has strange mapping.
Some registers of this PHY address are mapped to crevice of USB EHCI/OHCI register area.
like this
0xAAAA0000 ===========
EHCI
----------
0xAAAA0094 PHY
0xAAAA009C PHY
----------
EHCI
0xAAAA0400 ==========
...
0xAAAA0800 ----------
PHY
0xAAAA0900 ----------
This driver couldn't probe if it used "request_mem_region()"
Best regards
