mmc: rename mmc_can_trim() to mmc_card_can_trim()

2025-05-14T14:59:17Z

mmc_can_* functions sometimes relate to the card and sometimes to the host. Make it obvious by renaming this function to include 'card'. Also, convert to proper bool type while we are here.

mmc: core: Prepare to support SD UHS-II cards

2024-10-14T10:40:10Z

The SD UHS-II interface was introduced to the SD spec v4.00 several years ago. The interface is fundamentally different from an electrical and a protocol point of view, comparing to the legacy SD interface. However, the legacy SD protocol is supported through a specific transport layer (SD-TRAN) defined in the UHS-II addendum of the spec. This allows the SD card to be managed in a very similar way as a legacy SD card, hence a lot of code can be re-used to support these new types of cards through the mmc subsystem. Moreover, an SD card that supports the UHS-II interface shall also be backwards compatible with the legacy SD interface, which allows a UHS-II card to be inserted into a legacy slot. As a matter of fact, this is already supported by mmc subsystem as of today. To prepare to add support for UHS-II, this change puts the basic foundation in the mmc core in place, allowing it to be more easily reviewed before subsequent changes implements the actual support. Basically, the approach here adds a new UHS-II bus_ops type and adds a separate initialization path for the UHS-II card. The intent is to avoid us from sprinkling the legacy initialization path, but also to simplify implementation of the UHS-II specific bits. At this point, there is only one new host ops added to manage the various ios settings needed for UHS-II. Additional host ops that are needed, are being added from subsequent changes.

mmc: core: Disable card detect during shutdown

2021-12-20T10:09:15Z

It's seems prone to problems by allowing card detect and its corresponding mmc_rescan() work to run, during platform shutdown. For example, we may end up turning off the power while initializing a card, which potentially could damage it. To avoid this scenario, let's add ->shutdown_pre() callback for the mmc host class device and then turn of the card detect from there.

mmc: block: Support alternative_gpt_sector() operation

2021-08-24T16:09:06Z

Support generic alternative_gpt_sector() block device operation. It calculates location of GPT entry for eMMC of NVIDIA Tegra Android devices. Add new MMC_CAP2_ALT_GPT_TEGRA flag that enables scanning of alternative GPT sector and add raw_boot_mult field to mmc_ext_csd which allows to get size of the boot partitions that is needed for the calculation.
