While mmc0 enter suspend state, we need halt CQE to send legacy cmd(flush cache) and disable cqe, for resume back, we enable CQE and not clear HALT state. In this case MediaTek mmc host controller will keep the value for HALT state after CQE disable/enable flow, so the next CQE transfer after resume will be timeout due to CQE is in HALT state, the log as below: <4>.(4)[318:kworker/4:1H]mmc0: cqhci: timeout for tag 2 <4>.(4)[318:kworker/4:1H]mmc0: cqhci: ============ CQHCI REGISTER DUMP =========== <4>.(4)[318:kworker/4:1H]mmc0: cqhci: Caps: 0x100020b6 | Version: 0x00000510 <4>.(4)[318:kworker/4:1H]mmc0: cqhci: Config: 0x00001103 | Control: 0x00000001 <4>.(4)[318:kworker/4:1H]mmc0: cqhci: Int stat: 0x00000000 | Int enab: 0x00000006 <4>.(4)[318:kworker/4:1H]mmc0: cqhci: Int sig: 0x00000006 | Int Coal: 0x00000000 <4>.(4)[318:kworker/4:1H]mmc0: cqhci: TDL base: 0xfd05f000 | TDL up32: 0x00000000 <4>.(4)[318:kworker/4:1H]mmc0: cqhci: Doorbell: 0x8000203c | TCN: 0x00000000 <4>.(4)[318:kworker/4:1H]mmc0: cqhci: Dev queue: 0x00000000 | Dev Pend: 0x00000000 <4>.(4)[318:kworker/4:1H]mmc0: cqhci: Task clr: 0x00000000 | SSC1: 0x00001000 <4>.(4)[318:kworker/4:1H]mmc0: cqhci: SSC2: 0x00000001 | DCMD rsp: 0x00000000 <4>.(4)[318:kworker/4:1H]mmc0: cqhci: RED mask: 0xfdf9a080 | TERRI: 0x00000000 <4>.(4)[318:kworker/4:1H]mmc0: cqhci: Resp idx: 0x00000000 | Resp arg: 0x00000000 <4>.(4)[318:kworker/4:1H]mmc0: cqhci: CRNQP: 0x00000000 | CRNQDUN: 0x00000000 <4>.(4)[318:kworker/4:1H]mmc0: cqhci: CRNQIS: 0x00000000 | CRNQIE: 0x00000000 This change check HALT state after CQE enable, if CQE is in HALT state, we will clear it.

For dw_mmc, the ->init_card() callback is being used to turn on/off automatic internal clock gating for powersave, which is needed to properly support SDIO irqs on DAT1. However, using the ->init_card() comes with a drawback in this case, as it means that the powersave feature becomes disabled, no matter whether the SDIO irqs becomes turned on or not. To improve the behaviour, let's change into using the ->enable_sdio_irq() callback instead. This works fine, because dw_mmc uses sdio_signal_irq() to signal the irqs, thus the ->enable_sdio_irq() is never executed from within atomic context. Signed-off-by:

Commit f433e8aa ("mmc: sdhci-omap: Implement PM runtime functions") combined the use of runtime PM and system suspend functions but left the ifdef CONFIG_PM_SLEEP in place causing undeclared identifier error for sdhci_omap_runtime_suspend if CONFIG_PM_SLEEP is not enabled. Let's fix the error by removing ifdef CONFIG_PM_SLEEP and tagging the reset of the PM related functions with __maybe_unused. Let's also remove the forward declaration for sdhci_omap_context_save(), that was accidentally left from an earlier version and is no longer used. Reported-by:

The omap specific registers are at offset 0x100 from base for omap4 and later, and for omap3 and earlier they are at offset 0. Let's handle also the earlier SoCs by adding omap_offset.

In order to start deprecating the custom omap_hsmmc.c in favor of the generic sdhci-omap driver, we need to add support for voltages for earlier SoCs. The PBIAS regulator on omap4 and earlier only supports nominal values of 1.8V and 3.0V, while omap5 and later support nominal values of 1.8V and 3.3V IO voltage. This gets omap4/5 working with sdhci-omap driver. Signed-off-by:

Let's add compatible values for the legacy SoCs so we can continue deprecating omap_hsmmc in favor of sdhci-omap driver. For omap5, we want to have a separate compatible from omap4 for the additional features available on omap5. AFAIK ti81 can just use the omap4 compatible. Cc: devicetree@vger.kernel.org Acked-by:

To reset standard tuning circuit completely, after clear ESDHC_MIX_CTRL_EXE_TUNE, also need to clear bit buffer_read_ready, this operation will finally clear the USDHC IP internal logic flag execute_tuning_with_clr_buf, make sure the following normal data transfer will not be impacted by standard tuning logic used before. Find this issue when do quick SD card insert/remove stress test. During standard tuning prodedure, if remove SD card, USDHC standard tuning logic can't clear the internal flag execute_tuning_with_clr_buf. Next time when insert SD card, all data related commands can't get any data related interrupts, include data transfer complete interrupt, data timeout interrupt, data CRC interrupt, data end bit interrupt. Always trigger software timeout issue. Even reset the USDHC through bits in register SYS_CTRL (0x2C, bit28 reset tuning, bit26 reset data, bit 25 reset command, bit 24 reset all) can't recover this. From the user's point of view, USDHC stuck, SD can't be recognized any more. Fixes: d9370424 ("mmc: sdhci-esdhc-imx: reset tuning circuit when power on mmc card") Signed-off-by:

Intel Merrifield platform had been converted to use ACPI enumeration. However, the driver missed an update to retrieve card detect GPIO. Fix it here. Unfortunately we can't rely on CD GPIO state because there are two different PCB designs in the wild that are using the opposite card detection sense and there is no way to distinguish those platforms, that's why ignore CD GPIO completely and use it only as an event.

The "msh" pointer is device managed, meaning that memstick_alloc_host() calls device_initialize() on it. That means that it can't be free using kfree() but must instead be freed with memstick_free_host(). Otherwise it leads to a tiny memory leak of device resources.

The issue happens in several error handling paths on two refcounted object related to the object "host" (dma_chan_rx, dma_chan_tx). In these paths, the function forgets to decrement one or both objects' reference count increased earlier by dma_request_chan(), causing reference count leaks. Fix it by balancing the refcounts of both objects in some error handling paths. In correspondence with the changes in moxart_probe(), IS_ERR() is replaced with IS_ERR_OR_NULL() in moxart_remove() as well. Signed-off-by:
