2025-06-24mmc: sdhci_f_sdh30: Drop the use of sdhci_pltfm_free()Binbin Zhou
Since the devm_mmc_alloc_host() helper is already in use, sdhci_pltfm_free() is no longer needed.

2024-10-14mmc: Switch back to struct platform_driver::remove()Uwe Kleine-König
After commit 0edb555a65d1 ("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.

2023-08-15mmc: f-sdh30: Convert to platform remove callback returning voidYangtao Li
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.

2023-07-14mmc: sdhci-f-sdh30: Replace with sdhci_pltfmKunihiko Hayashi
Even if sdhci_pltfm_pmops is specified for PM, this driver doesn't apply sdhci_pltfm, so the structure is not correctly referenced in PM functions. This applies sdhci_pltfm to this driver to fix this issue. - Call sdhci_pltfm_init() instead of sdhci_alloc_host() and other functions that covered by sdhci_pltfm. - Move ops and quirks to sdhci_pltfm_data - Replace sdhci_priv() with own private function sdhci_f_sdh30_priv().

2019-11-13mmc: sdhci-milbeaut: add Milbeaut SD controller driverTakao Orito
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.

2018-01-11mmc: sdhci_f_sdh30: add ACPI supportArd Biesheuvel
The Fujitsu SDH30 SDHCI controller may be described as a SCX0002 ACPI device on ACPI platforms incorporating the Socionext SynQuacer SoC. Given that mmc_of_parse() has already been made ACPI/DT agnostic, making the SDH30 driver ACPI capable is actually rather simple: all we need to do is make the call to sdhci_get_of_property() [which does not set any properties we care about] and the clock handling dependent on whether we are dealing with a DT device, and exposing the ACPI id via the platform_driver struct and the module metadata.
