In sdhci_esdhc_imx_remove() the SDHCI_INT_STATUS in read. Under some circumstances, this may be done while the device is runtime suspended, triggering the below splat. Fix the problem by adding a pm_runtime_get_sync(), before reading the register, which will turn on clocks etc making the device accessible again.

2021-02-12mmc: mmc_test: use erase_arg for mmc_erase commandYann Gautier
Since [1], the erase argument for mmc_erase() function is saved in erase_arg field of card structure. It is preferable to use it instead of hard-coded MMC_SECURE_ERASE_ARG, which from eMMC 4.51 spec is not recommended: "6.6.16 Secure Erase NOTE Secure Erase is included for backwards compatibility. New system level implementations (based on v4.51 devices and beyond) should use Erase combined with Sanitize instead of secure erase." On STM32MP157C-EV1 board, embedding a THGBMDG5D1LBAIL eMMC, using MMC_ERASE command with MMC_SECURE_ERASE_ARG may stuck the STM32 SDMMC IP, if test 37 or test 38 are launched just after a write test, e.g. test 36. Using the default MMC_ERASE argument from framework with erase_arg, which default in our case to MMC_DISCARD_ARG does no more trig the issue.

2021-02-02amba: Make the remove callback return voidUwe Kleine-König
All amba drivers return 0 in their remove callback. Together with the driver core ignoring the return value anyhow, it doesn't make sense to return a value here. Change the remove prototype to return void, which makes it explicit that returning an error value doesn't work as expected. This simplifies changing the core remove callback to return void, too.

2021-02-01mmc: mmci: Add support for probing bus voltage level translatorMarek Vasut
Add support for testing whether bus voltage level translator is present and operational. This is useful on systems where the bus voltage level translator is optional, as the translator can be auto-detected by the driver and the feedback clock functionality can be disabled if it is not present. This requires additional pinmux state, "init", where the CMD, CK, CKIN lines are not configured, so they can be claimed as GPIOs early on in probe(). The translator test sets CMD high to avoid interfering with a card, and then verifies whether signal set on CK is detected on CKIN. If the signal is detected, translator is present, otherwise the CKIN feedback clock are disabled.

2021-02-01mmc: sdhci-msm: add Inline Crypto Engine supportEric Biggers
Add support for Qualcomm Inline Crypto Engine (ICE) to sdhci-msm. The standard-compliant parts, such as querying the crypto capabilities and enabling crypto for individual MMC requests, are already handled by cqhci-crypto.c, which itself is wired into the blk-crypto framework. However, ICE requires vendor-specific init, enable, and resume logic, and it requires that keys be programmed and evicted by vendor-specific SMC calls. Make the sdhci-msm driver handle these details. This is heavily inspired by the similar changes made for UFS, since the UFS and eMMC ICE instances are very similar. See commit df4ec2fa7a4d ("scsi: ufs-qcom: Add Inline Crypto Engine support"). I tested this on a Sony Xperia 10, which uses the Snapdragon 630 SoC, which has basic upstream support. Mainly, I used android-xfstests (https://github.com/tytso/xfstests-bld/blob/master/Documentation/android-xfstests.md) to run the ext4 and f2fs encryption tests in a Debian chroot: android-xfstests -c ext4,f2fs -g encrypt -m inlinecrypt These tests included tests which verify that the on-disk ciphertext is identical to that produced by a software implementation. I also verified that ICE was actually being used.

2021-02-01mmc: cqhci: add cqhci_host_ops::program_keyEric Biggers
On Snapdragon SoCs, the Linux kernel isn't permitted to directly access the standard CQHCI crypto configuration registers. Instead, programming and evicting keys must be done through vendor-specific SMC calls. To support this hardware, add a ->program_key() method to 'struct cqhci_host_ops'. This allows overriding the standard CQHCI crypto key programming / eviction procedure. This is inspired by the corresponding UFS crypto support, which uses these same SMC calls. See commit 1bc726e26ef3 ("scsi: ufs: Add program_key() variant op").

2021-02-01mmc: cqhci: add support for inline encryptionEric Biggers
Add support for eMMC inline encryption using the blk-crypto framework (Documentation/block/inline-encryption.rst). eMMC inline encryption support is specified by the upcoming JEDEC eMMC v5.2 specification. It is only specified for the CQ interface, not the non-CQ interface. Although the eMMC v5.2 specification hasn't been officially released yet, the crypto support was already agreed on several years ago, and it was already implemented by at least two major hardware vendors. Lots of hardware in the field already supports and uses it, e.g. Snapdragon 630 to give one example. eMMC inline encryption support is very similar to the UFS inline encryption support which was standardized in the UFS v2.1 specification and was already upstreamed. The only major difference is that eMMC limits data unit numbers to 32 bits, unlike UFS's 64 bits. Like we did with UFS, make the crypto support opt-in by individual drivers; don't enable it automatically whenever the hardware declares crypto support. This is necessary because in every case we've seen, some extra vendor-specific logic is needed to use the crypto support.

Move the task descriptor initialization into cqhci_prep_task_desc(). In addition, make it explicitly initialize all 128 bits of the task descriptor if the host controller is using 128-bit task descriptors, rather than relying on the implicit zeroing from dmam_alloc_coherent(). This is needed to prepare for CQHCI inline encryption support, which requires 128-bit task descriptors and uses the upper 64 bits.

2021-02-01mmc: core: Add basic support for inline encryptionEric Biggers
In preparation for adding CQHCI crypto engine (inline encryption) support, add the code required to make mmc_core and mmc_block aware of inline encryption. Specifically: - Add a capability flag MMC_CAP2_CRYPTO to struct mmc_host. Drivers will set this if the host and driver support inline encryption. - Embed a blk_keyslot_manager in struct mmc_host. Drivers will initialize this (as a device-managed resource) if the host and driver support inline encryption. mmc_block registers this keyslot manager with the request_queue of any MMC card attached to the host. - Make mmc_block copy the crypto keyslot and crypto data unit number from struct request to struct mmc_request, so that drivers will have access to them. - If the MMC host is reset, reprogram all the keyslots to ensure that the software state stays in sync with the hardware state.

The RPi4 has an Arasan controller it carries over from the RPi3 and a newer eMMC2 controller. Because of a couple of quirks, it seems wiser to bind these controllers to the same driver that DT is using on this platform rather than the generic sdhci_acpi driver with PNP0D40. So, BCM2847 describes the older Arasan and BRCME88C describes the newer eMMC2. The older Arasan is reusing an existing ACPI _HID used by other OSes booting these tables on the RPi. With this change, Linux is capable of utilizing the SD card slot, and the Wi-Fi when booted with UEFI+ACPI on the RPi4.

The hardware supports independent configuration for both bus directions on a per-slot basis. The timing delay per element encoded in the driver was experimentally determined by scope measurements. The phase controls for both slots are grouped together in a single register of the global register block of the SD/MMC controller(s), which drives the use of a locking scheme between the SDHCIs and the global register set.
