2024-10-22mmc: block: attach partitions fwnode if found in mmc-cardChristian Marangi
Attach partitions fwnode if found in mmc-card and register disk with it. This permits block partition to reference the node and register a partition table defined in DT for the special case for embedded device that doesn't have a partition table flashed but have an hardcoded partition table passed from the system. JEDEC BOOT partition boot0/boot1 are supported but in DT we refer with the JEDEC name of boot1 and boot2 to better adhere to documentation. Also JEDEC GP partition gp0/1/2/3 are supported but in DT we refer with the JEDEC name of gp1/2/3/4 to better adhere to documentration.

2024-10-14mmc: core: Extend support for mmc regulators with a vqmmc2Ulf Hansson
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().

2024-10-14mmc: core: Announce successful insertion of an SD UHS-II cardUlf Hansson
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.

2024-10-14mmc: core: Prepare to support SD UHS-II cardsUlf Hansson
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.

2024-10-14mmc: core: Adjust ACMD22 to SDUCAvri Altman
ACMD22 is used to verify the previously write operation. Normally, it returns the number of written sectors as u32. SDUC, however, returns it as u64. This is not a superfluous requirement, because SDUC writes may exceeds 2TB. For Linux mmc however, the previously write operation could not be more than the block layer limits, thus we make room for a u64 and cast the returning value to u32.

The SDUC spec expects CMD22 to get squeezed between CMD23 and the read/write command, e.g. CMD23->CMD22->CMD18 and CMD23->CMD22->CMD25.

SDUC memory addressing spans beyond 2TB and up to 128TB. Therefore, 38 bits are required to access the entire memory space of all sectors. Those extra 6 bits are to be carried by CMD22 prior of sending read/write/erase commands: CMD17, CMD18, CMD24, CMD25, CMD32, and CMD33. CMD22 will carry the higher order 6 bits, and must precedes any of the above commands even if it targets sector < 2TB.

2024-10-14mmc: sd: SDUC Support RecognitionAvri Altman
Ultra Capacity SD cards (SDUC) was already introduced in SD7.0. Those cards support capacity larger than 2TB and up to including 128TB. ACMD41 was extended to support the host-card handshake during initialization. The card expects that the HCS & HO2T bits to be set in the command argument, and sets the applicable bits in the R3 returned response. On the contrary, if a SDUC card is inserted to a non-supporting host, it will never respond to this ACMD41 until eventually, the host will timed out and give up. Also, add SD CSD version 3.0 - designated for SDUC, and properly parse the csd register as the c_size field got expanded to 28 bits. Do not enable SDUC for now - leave it to the last patch in the series.

After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return void") .remove() is (again) the right callback to implement for platform drivers.

2024-10-14mmc: core: Add SD card quirk for broken poweroff notificationKeita Aihara
GIGASTONE Gaming Plus microSD cards manufactured on 02/2022 report that they support poweroff notification and cache, but they are not working correctly. Flush Cache bit never gets cleared in sd_flush_cache() and Poweroff Notification Ready bit also never gets set to 1 within 1 second from the end of busy of CMD49 in sd_poweroff_notify(). This leads to I/O error and runtime PM error state. I observed that the same card manufactured on 01/2024 works as expected. This problem seems similar to the Kingston cards fixed with commit c467c8f08185 ("mmc: Add MMC_QUIRK_BROKEN_SD_CACHE for Kingston Canvas Go Plus from 11/2019") and should be handled using quirks. CID for the problematic card is here. 12345641535443002000000145016200 Manufacturer ID is 0x12 and defined as CID_MANFID_GIGASTONE as of now, but would like comments on what naming is appropriate because MID list is not public and not sure it's right.

This reached across all bus types, and there are some fix-ups for some not-common bus types that linux-next and 0-day testing shook out.

2024-07-03driver core: have match() callback in struct bus_type take a const *Greg Kroah-Hartman
In the match() callback, the struct device_driver * should not be changed, so change the function callback to be a const *. This is one step of many towards making the driver core safe to have struct device_driver in read-only memory. Because the match() callback is in all busses, all busses are modified to handle this properly. This does entail switching some container_of() calls to container_of_const() to properly handle the constant *. For some busses, like PCI and USB and HV, the const * is cast away in the match callback as those busses do want to modify those structures at this point in time (they have a local lock in the driver structure.) That will have to be changed in the future if they wish to have their struct device * in read-only-memory. Cc: Rafael J.

Move the nonrot flag into the queue_limits feature field so that it can be set atomically with the queue frozen. Use the chance to switch to defaulting to non-rotational and require the driver to opt into rotational, which matches the polarity of the sysfs interface. For the z2ram, ps3vram, 2x memstick, ubiblock and dcssblk the new rotational flag is not set as they clearly are not rotational despite this being a behavior change. There are some other drivers that unconditionally set the rotational flag to keep the existing behavior as they arguably can be used on rotational devices even if that is probably not their main use today (e.g. virtio_blk and drbd). The flag is automatically inherited in blk_stack_limits matching the existing behavior in dm and md.

2024-06-19block: move cache control settings out of queue->flagsChristoph Hellwig
Move the cache control settings into the queue_limits so that the flags can be set atomically with the device queue frozen. Add new features and flags field for the driver set flags, and internal (usually sysfs-controlled) flags in the block layer. Note that we'll eventually remove enough field from queue_limits to bring it back to the previous size. The disable flag is inverted compared to the previous meaning, which means it now survives a rescan, similar to the max_sectors and max_discard_sectors user limits. The FLUSH and FUA flags are now inherited by blk_stack_limits, which simplified the code in dm a lot, but also causes a slight behavior change in that dm-switch and dm-unstripe now advertise a write cache despite setting num_flush_bios to 0. The I/O path will handle this gracefully, but as far as I can tell the lack of num_flush_bios and thus flush support is a pre-existing data integrity bug in those targets that really needs fixing, after which a non-zero num_flush_bios should be required in dm for targets that map to underlying devices.

2024-04-26mmc: core: Add mmc_gpiod_set_cd_config() functionHans de Goede
Some mmc host drivers may need to fixup a card-detection GPIO's config to e.g. enable the GPIO controllers builtin pull-up resistor on devices where the firmware description of the GPIO is broken (e.g. GpioInt with PullNone instead of PullUp in ACPI DSDT). Since this is the exception rather then the rule adding a config parameter to mmc_gpiod_request_cd() seems undesirable, so instead add a new mmc_gpiod_set_cd_config() function. This is simply a wrapper to call gpiod_set_config() on the card-detect GPIO acquired through mmc_gpiod_request_cd().

2024-04-02mmc: sdio: store owner from modules with sdio_register_driver()Krzysztof Kozlowski
Modules registering driver with sdio_register_driver() might forget to set .owner field. The field is used by some of other kernel parts for reference counting (try_module_get()), so it is expected that drivers will set it. Solve the problem by moving this task away from the drivers to the core code, just like we did for platform_driver in commit 9447057eaff8 ("platform_device: use a macro instead of platform_driver_register"). Since many drivers forget to set the .owner, this effectively will fix them. Examples of fixed drivers are: ath6kl, b43, btsdio.c, ks7010, libertas, MediaTek WiFi drivers, Realtek WiFi drivers, rsi, siano, wilc1000, wl1251 and more.
