I accidentally used an older shortlog and diffstat in that cover mail;
here are the correct ones.

All the SHDIs can operate with either 3.3V or 1.8V signals, depending
on negotiation with the card.
Implement the {get,set}_low_voltage operations and set the low-voltage
capability flag for the associated pins.

The pfc in the R8A7790 (and probably others in the R-Car gen 2 family)
supports switching SDHI signals between 3.3V and 1.8V voltage, and the
SD driver should do that when selecting a higher-speed mode.
Add a flag for pins that support low voltage mode and SoC operations to
get and set it. Implem
This series adds support for UHS-I in sh_mobile_sdhi, partly implemented
in tmio_mmc. This does not yet include tuning for SDR-104, but SDR-50 now
works on the R8A7790 Lager board and another development board.
The pfc block needs to be reconfigured from 3.3V to 1.8V signalling on

Based on work by Shinobu Uehara and Ben Dooks. This adds the voltage
switch operation needed for all UHS-I modes, but not the tuning needed
for SDR-104 which will come later.
The card_busy implementation is a bit of a guess, but works for me on
an R8A7790 chip.

Ensure SDCC is working with maximum clock otherwise card
detection could be extremely slow, up to 7 seconds.

As i know, when there is no card detection scheme, BROKEN_CARD_DETECTION quirks
is set.
If it can use CD_GPIO, doesn't it need to se

Controller could have both NO_CARD_NO_RESET and BROKEN_CARD_DETECTION
quirks set. Use sdhci_do_get_cd() when applying NO_CARD_NO_RESET, which
properly check for BROKEN_CARD_DETECTION quirk.

There is no reason to use polling for card detection state change when
drivers are using dedicated GPIO for this. Don't poll in this case.
