dbbbdeabf6 mmc: sdhci-milbeaut: Drop the use of sdhci_free_host()
Since the devm_mmc_alloc_host() helper is already in use,
sdhci_free_host() is no longer needed.

078e548af9 mmc: Switch back to struct platform_driver::remove()
After commit 0edb555a65 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.

Convert all platform drivers below drivers/mmc to use .remove(), with
the eventual goal to drop struct platform_driver::remove_new(). As
.remove() and .remove_new() have the same prototypes, conversion is done
by just changing the structure member name in the driver initializer.

9479a63131 mmc: sdhci: milbeaut: Convert to platform remove callback returning void
The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is (mostly) ignored
and this typically results in resource leaks. To improve here there is a
quest to make the remove callback return void. In the first step of this
quest all drivers are converted to .remove_new() which already returns
void.

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

8069a60a05 mmc: sdhci: milbeaut: remove redundant of_match_ptr()
The driver depends on CONFIG_OF, so it is not necessary to use
of_match_ptr() here. We remove of_match_ptr() here.

31ae403513 mmc: Set PROBE_PREFER_ASYNCHRONOUS for drivers that are newer than 5.4
This is like commit 3d3451124f3d ("mmc: sdhci-msm: Prefer asynchronous
probe") but applied to a whole pile of drivers.  This batch converts
the drivers that appeared to have been added after kernel 5.4.

d2abc6e2b5 mmc: sdhci: milbeaut: Use sdhci_set_power_and_voltage()
The sdhci core provides a helper function with the same functionality as
this controller's set_power() callback. Use it instead.

557c03157c mmc: sdhci-milbeaut: Remove redundant platform_get_irq error message
platform_get_irq() will call dev_err() itself on failure,
so there is no need for the driver to also do this.
This is detected by coccinelle.

dd79b7e367 mmc: sdhci-milbeaut: add Milbeaut SD controller driver
SD Host controller on Milbeaut consists of two controller parts.
One is core controller F_SDH30, this is similar to sdhci-fujitsu
controller.
Another is bridge controller.
This bridge controller is not compatible with sdhci-fujitsu controller.
This is special for Milbeaut series. This has some functions.
For example, reset control, clock enable/select for SDR50/25/12, set
property of SD physical pins, retuning control, set capabilityies.

This bridge controller requires special procedures at reset or clock
enablement or change for further tuning of clock.
