mmc: core: Cleanup BKOPS support
It's been ~6 years ago since we introduced the BKOPS support for eMMC cards. The current code is a bit messy and primarily that's because it prepares to support running BKOPS in an asynchronous mode. However, that mode has never been fully implemented/enabled. Instead BKOPS is always executed in synchronously, when the card has reported an urgent BKOPS level. For these reasons, let's make the code more readable by dropping the unused parts. Let's also rename mmc_start_bkops() to mmc_run_bkops(), as to make it more descriptive.

mmc: core: Drop redundant check in mmc_send_hpi_cmd()
There is no point checking if HPI is supported in mmc_send_hpi_cmd() as mmc_interrupt_hpi(), which is the only caller, already checks if HPI has been enabled. Therefore, let's drop the check and the corresponding error path. Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org> |

mmc: core: Use a minimum 1600ms timeout when enabling CACHE ctrl
Some eMMCs from Micron have been reported to need ~800 ms timeout, while enabling the CACHE ctrl after running sudden power failure tests. The needed timeout is greater than what the card specifies as its generic CMD6 timeout, through the EXT_CSD register, hence the problem. Normally we would introduce a card quirk to extend the timeout for these specific Micron cards. However, due to the rather complicated debug process needed to find out the error, let's simply use a minimum timeout of 1600ms, the double of what has been reported, for all cards when enabling CACHE ctrl.

mmc: core: Reset HPI enabled state during re-init and in case of errors
During a re-initialization of the eMMC card, we may fail to re-enable HPI.
In these cases, that isn't properly reflected in the card->ext_csd.hpi_en
bit, as it keeps being set. This may cause following attempts to use HPI,
even if's not enabled. Let's fix this!

mmc: core: Introduce MMC_CAP_SYNC_RUNTIME_PM
To allow mmc host drivers to inform the mmc core about rather using pm_runtime_put_sync_suspend() instead of pm_runtime_put_autosuspend(), let's introduce MMC_CAP_SYNC_RUNTIME_PM. This is especially useful for those mmc host drivers that don't benefit from using the runtime PM autosuspend feature. Typically this is those that relies on parent devices to power the card via runtime PM, like some USB host drivers for example.

mmc: core: use mrq->sbc when sending CMD23 for RPMB
When sending out CMD23 in the blk preparation, the comment there rightfully says: * However, it is not sufficient to just send CMD23, * and avoid the final CMD12, as on an error condition * CMD12 (stop) needs to be sent anyway. This, coupled * with Auto-CMD23 enhancements provided by some * hosts, means that the complexity of dealing * with this is best left to the host. If CMD23 is * supported by card and host, we'll fill sbc in and let * the host deal with handling it correctly. Let's do this behaviour for RPMB as well, and not send CMD23 independently. Otherwise IP cores (like Renesas SDHI) may timeout because of automatic CMD23/CMD12 handling.

This is the bulk of GPIO changes for the v4.20 series:
Core changes: - A patch series from Hans Verkuil to make it possible to enable/disable IRQs on a GPIO line at runtime and drive GPIO lines as output without having to put/get them from scratch. The irqchip callbacks have been improved so that they can use only the fastpatch callbacks to enable/disable irqs like any normal irqchip, especially the gpiod_lock_as_irq() has been improved to be callable in fastpath context. A bunch of rework had to be done to achieve this but it is a big win since I never liked to restrict this to slowpath. The only call requireing slowpath was try_module_get() and this is kept at the .request_resources() slowpath callback. In the GPIO CEC driver this is a big win sine a single line is used for both outgoing and incoming traffic, and this needs to use IRQs for incoming traffic while actively driving the line for outgoing traffic. - Janusz Krzysztofik improved the GPIO array API to pass a "cookie" (struct gpio_array) and a bitmap for setting or getting multiple GPIO lines at once. This improvement orginated in a specific need to speed up an OMAP1 driver and has led to a much better API and real performance gains when the state of the array can be used to bypass a lot of checks and code when we want things to go really fast. The previous code would minimize the number of calls down to the driver callbacks assuming the CPU speed was orders of magnitude faster than the I/O latency, but this assumption was wrong on several platforms: what we needed to do was to profile and improve the speed on the hot path of the array functions and this change is now completed. - Clean out the painful and hard to grasp BNF experiments from the device tree bindings. Future approaches are looking into using JSON schema for this purpose. (Rob Herring is floating a patch series.) New drivers: - The RCAR driver now supports r8a774a1 (RZ/G2M). - Synopsys GPIO via CREGs driver. Major improvements: - Modernization of the EP93xx driver to use irqdomain and other contemporary concepts. - The ingenic driver has been merged into the Ingenic pin control driver and removed from the GPIO subsystem. - Debounce support in the ftgpio010 driver. -----BEGIN PGP SIGNATURE----- iQIcBAABAgAGBQJbzdyOAAoJEEEQszewGV1zfYcP/0HBEAOPhHD/i5OQxfKs1msh mFT/t/IbTmRpCgbEv4CDx4Kc/InE0sUnQr1TL/1WvU6uObM6Ncxq5Z90MvyrgzYu BqQHq2k2tORvkVSNRxcfD/BAAoo1EerXts1kDhutvdKfepfS6DxpENwzvsFgkVlq 2jj1cdZztjv8A+9cspHDpQP+jDvl1VSc10nR5fRu1TttSpUwzRJaB30NBNXJmMJc 5KUr67lEbsQRPsBvFErU11bydPqhfT+pXmODcfIwS0EtATQ8WC5mkSb/Ooei0fvT oZ7uR3Os8tMf7isOKssEyFabKwhnfOEt6TBt9em0TfUtInOo0Dc7r8TfBcn57fyZ xg2R9DQEVRfac8bjhF/BI5KHuN9IMGDDvj6XApumQVliZbISRjMnh3jte6RpcV0A Ejqz8FeDY13qvEdOnW1EPpwmXdDVWiEAq0ebGLStKNls+/4gB2HmyxGUOzJf+og5 hujsxcJzGQqjCe0moeY/1d7vsy0ZjbHoS+p5fy79U212y2O7onEzFU92AX89bxKC rx2eCNmiZxCUy1nqu8edO62VnH6QdnqG3o+a4DJfCSHPvFM/E/NX9zHemZubQQ4I rYXNy4bL4tEG9cqWMfBxWrpiDZw7H6l8kXwdZG8IMyRU9BcKu96amgZ+jBXwzoaB JZelAAUWB9APghJYFr7o =YosT -----END PGP SIGNATURE----- Merge tag 'gpio-v4.20-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio Pull GPIO updates from Linus Walleij: "This is the bulk of GPIO changes for the v4.20 series: Core changes: - A patch series from Hans Verkuil to make it possible to enable/disable IRQs on a GPIO line at runtime and drive GPIO lines as output without having to put/get them from scratch.

gpiolib: Pass array info to get/set array functions

gpiolib: Pass bitmaps, not integer arrays, to get/set array
Most users of get/set array functions iterate consecutive bits of data, usually a single integer, while processing array of results obtained from, or building an array of values to be passed to those functions. Save time wasted on those iterations by changing the functions' API to accept bitmaps. All current users are updated as well. More benefits from the change are expected as soon as planned support for accepting/passing those bitmaps directly from/to respective GPIO chip callbacks if applicable is implemented.

mmc: block: Fix unsupported parallel dispatch of requests
The mmc block driver does not support parallel dispatch of requests. In
normal circumstances, all requests are anyway funneled through a single
work item, so parallel dispatch never happens. However it can happen if
there is no elevator.
Fix that by detecting if a dispatch is in progress and returning busy
(BLK_STS_RESOURCE) in that case

mmc: core: more fine-grained hooks for HS400 tuning
This adds two new HS400 tuning operations: * hs400_downgrade * hs400_complete These supplement the existing HS400 operation: * prepare_hs400_tuning This is motivated by a requirement of Renesas SDHI for the following: 1. Disabling SCC before selecting to HS if selection of HS400 has occurred. This can be done in an implementation of prepare_hs400_tuning_downgrade 2. Updating registers after switching to HS400 This can be done in an implementation of complete_hs400_tuning If hs400_downgrade or hs400_complete are not implemented then they are not called. Thus means there should be no affect for existing drivers as none implemt these ops. Signed-off-by: Simon Horman <horms+renesas@verge.net.au> Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org> |

mmc: core: Adjust and reuse the macro of R1_STATUS(x)
R1_STATUS(x) now is only used by ioctl_rpmb_card_status_poll(), which checks all bits as possible. But according to the spec, bit 17 and bit 18 should be ignored, as well bit 14 which is reserved(must be set to 0) quoting from the spec and these rule apply to all places checking the device status. So change its checking from 0xFFFFE000 to 0xFFF9A000. As a bonus, we reuse it for mmc_do_erase() as well as mmc_switch_status_error(). (1) Currently mmc_switch_status_error() doesn't check bit 25, but it means device is locked but not unlocked by CMD42 prior to any operations which need check busy, which is also not allowed. (2) mmc_do_erase() also forgot to to check bit 15, WP_ERASE_SKIP. The spec says "Only partial address space was erased due to existing write protected blocks.", which obviously means we should fail this I/O. Otherwise, the partial erased data stored in nonvalatile flash violates the data integrity from the view of I/O owner, which probably confuse it when further used. So reusing R1_STATUS for them not only improve the readability but also slove real problems. Signed-off-by: Shawn Lin <shawn.lin@rock-chips.com> Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org> |

mmc: Throttle calls to MMC_SEND_STATUS during mmc_do_erase()
This drastically reduces the rate at which the MMC_SEND_STATUS cmd polls for completion of the MMC Erase operation. The patch does this by adding a backoff sleep that starts by sleeping for short intervals (128-256us), and ramps up to sleeping for 32-64ms. Even on very quickly completing erase operations, the loop iterates a few times, so not too much extra latency is added to these commands. For long running discard operarations, like a full-device secure discard, this change drops the interrupt rates on my single-core NXP I.MX6UL from 45000/s to about 20/s, and greatly improves system responsiveness.

mmc: Allow non-sleeping GPIO cd
This change uses the appropriate _cansleep or non-sleeping API for reading GPIO card detect state. This allows users with GPIOs that never sleep to avoid a warning when certain quirks are present. The sdhci controller has an SDHCI_QUIRK_NO_CARD_NO_RESET, which indicates that a controller will not reset properly if no card is inserted. With this quirk enabled, mmc_get_cd_gpio is called in several places with a spinlock held and interrupts disabled. gpiod_get_raw_value_cansleep is not happy with this situation, and throws out a warning. For boards that a) use controllers that have this quirk, and b) wire card detect up to a GPIO that doesn't sleep, this is a spurious warning. This change silences that warning, at the cost of pushing this problem down to users that have sleeping GPIOs and controllers with this quirk.

mmc: block: Don't switch to the same partition type in mmc_blk_remove()
It's pointless to switch and trace partition type if the current selected device partition is the same with that one. Moreover, cycled claiming host associated with mmc_blk_part_switch() could make mmc_blk_remove() end up waiting for grabbing the context if it's occupied, which lead requests could still hit the low-level drivers, if an asynchronous unbind for host drivers happened, as the card hasn't been set removed in the remove path. So a simple dd in background: dd if=/dev/mmcblk0 of=/dev/null bs=512k count=100000 & and doing unbind then: echo fe320000.dwmmc > /sys/bus/platform/drivers/dwmmc_rockchip/unbind could make the console stuck for quite a while depending on the numbers of requests.
