Yes, most of this data can be removed, such as caps, caps2, base_clk.
However ocr_avail and signal_default_voltage are useful for us.
We can't fetch ocr_avail from external regulator via
mmc_regulator_get_supply,
because our regulator driver can't supply mmc_regulator_get_ocrmask()
interface for MMC driver.

Sorry for the noise but... IMO, your need to quirk your regulator driver
stuffs rather than mmc.

Thank you, Shawn. I'll do it.

And sometimes our external regulator can not supply 3.0v or 1.8v default

signal voltage that we expect. So this 3.0v or 1.8v default signal
voltage are
mandatory.
