Hi, Some quick comments 2014-12-05 13:52 GMT+01:00 Yunzhi Li <lyz@xxxxxxxxxxxxxx>: > This patche to add a generic PHY driver for ROCKCHIP usb PHYs, > currently this driver can support RK3288.

I think that PHY_ROCKCHIP_USB would be enough. > +#include <linux/regmap.h> > +#include <linux/mfd/syscon.h> > + > +#define ROCKCHIP_RK3288_UOC(n) (0x320 + n * 0x14) > + > +#define SIDDQ_MSK (1 << (13 + 16)) > +#define SIDDQ_ON (1 << 13) You could probably use BIT(13) and BIT(13+16) here.
