2023-08-25mmc: atmel-mci: Move card detect gpio polarity quirk to gpiolibBalamanikandan Gunasundar1-18/+15
The polarity of the card detection gpio is handled by the "cd-inverted" property in the device tree. Move this inversion logic to gpiolib to avoid reading the gpio raw value.

Replace the legacy GPIO APIs with gpio descriptor consumer interface. To maintain backward compatibility, we rely on the "cd-inverted" property to manage the invertion flag instead of GPIO property.

2023-08-25mmc: sdhci-sprd: Add SD HS mode online tuningWenchao Chen1-0/+149
First of all, Unisoc's IC provides cmd delay and read delay to ensure that the host can get the correct data. However, according to SD Spec, there is no need to do tuning in high speed mode, but with the development of chip processes, it is more and more difficult to find a suitable delay to cover all the chips. Therefore, we need SD high speed mode online tuning. In addition, we added mmc_sd_switch() and mmc_send_status() to the header file to allow it to be usable by the driver.

2023-08-25mmc: core: Add host specific tuning support for SD HS modeWenchao Chen4-3/+15
To support the need for host specific tuning for SD high-speed mode, let's add two new optional callbacks, ->prepare|execute_sd_hs_tuning() and let's call them when switching into the SD high-speed mode. Note that, during the tuning process it's also needed for host drivers to send commands to the SD card to verify that the tuning process succeeds. Therefore, let's also share the corresponding functions from the core to allow this.

Errata ERR010450 only shows up if voltage is 1.8V, but if the device is supplied by 3v3 the errata can be ignored. So let's check for if quirk SDHCI_QUIRK2_NO_1_8_V is defined or not before limiting the frequency.

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.
