mmc: core: Add definitions for SD UHS-II cards

2024-10-14T10:40:10Z

Add UHS-II specific data structures for commands and defines for registers, as described in Part 1 UHS-II Addendum Version 1.01. UHS-II related definitions are listed below: 1. UHS-II card capability: sd_uhs2_caps{} 2. UHS-II configuration: sd_uhs2_config{} 3. UHS-II register I/O address and register field definitions: sd_uhs2.h Signed-off-by: Jason Lai Signed-off-by: Victor Shih Link: https://lore.kernel.org/r/20240913102836.6144-6-victorshihgli@gmail.com Signed-off-by: Ulf Hansson

mmc: core: Extend support for mmc regulators with a vqmmc2

2024-10-14T10:40:10Z

To allow an additional external regulator to be controlled by an mmc host driver, let's add support for a vqmmc2 regulator to the mmc core. For an SD UHS-II interface the vqmmc2 regulator may correspond to the so called vdd2 supply, as described by the SD spec. Initially, only 1.8V is needed, hence limit the new helper function, mmc_regulator_set_vqmmc2() to this too. Note that, to allow for flexibility mmc host drivers need to manage the enable/disable of the vqmmc2 regulator themselves, while the regulator is looked up through the common mmc_regulator_get_supply().

mmc: core: Announce successful insertion of an SD UHS-II card

2024-10-14T10:40:10Z

To inform the users about SD UHS-II cards, let's extend the print at card insertion with a "UHS-II" substring. Within this change, it seems reasonable to convert from using "ultra high speed" into "UHS-I speed", for the UHS-I type, as it should makes it more clear. Note that, the new print for UHS-II cards doesn't include the actual selected speed mode. Instead, this is going to be added from subsequent change.

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.

fault-inject: improve build for CONFIG_FAULT_INJECTION=n

2024-09-02T03:43:33Z

The fault-inject.h users across the kernel need to add a lot of #ifdef CONFIG_FAULT_INJECTION to cater for shortcomings in the header. Make fault-inject.h self-contained for CONFIG_FAULT_INJECTION=n, and add stubs for DECLARE_FAULT_ATTR(), setup_fault_attr(), should_fail_ex(), and should_fail() to allow removal of conditional compilation.
