Probably, the author of the driver can comment on this. I have cc'ed
all of them.

But looking at the driver it looks like, except onkey and regulator all
other devices need per-initialization. For example,

in case of clock,

static int device_clk_init(struct pm80x_chip *chip)
{
         if (chip->type == CHIP_PM800)
                 clk_devs[0].name = "88pm800-clk";
         else if (chip->type == CHIP_PM860)
                 clk_devs[0].name = "88pm860-clk";

         return mfd_add_devices(chip->dev, 0, &clk_devs[0],
                               ARRAY_SIZE(clk_devs), NULL, 0, NULL);
}

Ok, I will.
