dma_request_slave_channel() is a wrapper on top of dma_request_chan() eating up the error code. By using dma_request_chan() directly the driver can support deferred probing against DMA. Signed-off-by:

The erratum A-009204 workaround patch was reverted because of incorrect implementation. 8b6dc6b2 mmc: sdhci-of-esdhc: Revert "mmc: sdhci-of-esdhc: add erratum A-009204 support" This patch is to re-implement the workaround (add a 5 ms delay before setting SYSCTL[RSTD] to make sure all the DMA transfers are finished).

For the ux500v2 variant of the PL18x block, any block sizes are supported. This is necessary to support some SDIO transfers. This also affects the QCOM MMCI variant and the ST micro variant. For Ux500 an additional quirk only allowing DMA on blocks that are a power of two is needed. This might be a bug in the DMA engine (DMA40) or the MMCI or in the interconnect, but the most likely is the MMCI, as transfers of these sizes work fine for other devices using the same DMA engine. DMA works fine also with SDIO as long as the blocksize is a power of 2. This patch has proven necessary for enabling SDIO for WLAN on PostmarketOS-based Ux500 platforms. What we managed to test in practice is Broadcom WiFi over SDIO on the Ux500 based Samsung GT-I8190 and GT-S7710. This WiFi chip, BCM4334 works fine after the patch. Before this patch: brcmfmac: brcmf_fw_alloc_request: using brcm/brcmfmac4334-sdio for chip BCM4334/3 mmci-pl18x 80118000.sdi1_per2: unsupported block size (60 bytes) brcmfmac: brcmf_sdiod_ramrw: membytes transfer failed brcmfmac: brcmf_sdio_download_code_file: error -22 on writing 434236 membytes at 0x00000000 brcmfmac: brcmf_sdio_download_firmware: dongle image file download failed After this patch: brcmfmac: brcmf_c_preinit_dcmds: Firmware: BCM4334/3 wl0: Nov 21 2012 00:21:28 version 6.10.58.813 (B2) FWID 01-0 Bringing up networks, discovering networks with "iw dev wlan0 scan" and connecting works fine from this point. This patch is inspired by Ulf Hansson's patch http://www.spinics.net/lists/linux-mmc/msg12160.html As the DMA engines on these platforms may now get block sizes they were not used to before, make sure to also respect if the DMA engine says "no" to a transfer. Make a drive-by fix for datactrl_blocksz, misspelled.

platform_get_resource(pdev, IORESOURCE_IRQ) is not recommended for requesting IRQ's resources, as they can be not ready yet. Using platform_get_irq() instead is preferred for getting IRQ even if it was not retrieved earlier. Signed-off-by:

Command queuing has been reported broken on some systems based on Intel GLK. A separate patch disables command queuing in some cases. This patch adds a quirk for broken command queuing, which enables users with problems to disable command queuing using sdhci module parameters for quirks.

Two previous patches introduced below quirks for P2020 platforms. - SDHCI_QUIRK_RESET_AFTER_REQUEST - SDHCI_QUIRK_BROKEN_TIMEOUT_VAL The patches made a mistake to add them in quirks2 of sdhci_host structure, while they were defined for quirks. host->quirks2 |= SDHCI_QUIRK_RESET_AFTER_REQUEST; host->quirks2 |= SDHCI_QUIRK_BROKEN_TIMEOUT_VAL; This patch is to fix them. host->quirks |= SDHCI_QUIRK_RESET_AFTER_REQUEST; host->quirks |= SDHCI_QUIRK_BROKEN_TIMEOUT_VAL; Fixes: 05cb6b2a ("mmc: sdhci-of-esdhc: add erratum eSDHC-A001 and A-008358 support") Fixes: a46e4271 ("mmc: sdhci-of-esdhc: add erratum eSDHC5 support") Signed-off-by:

The stm32_sdmmc variant has build-in support for datatimeout for R1B requests. If a corresponding IRQ is raised, this triggers the DPSM to stay busy and remains in a non-functional state. Only a reset can bring it back to a functional state. Because a reset must be issued from non-atomic context, let's defer this to be managed from a threaded IRQ handler. Besides the reset, the threaded handler also calls mmc_request_done(), to finally complete the request. Signed-off-by:

There are a few places around the code that invert inverted and possibly inverted CD line. That's really confusing. Squash them all into one place in mmc_gpiod_request_cd(). MMC_CAP2_CD_ACTIVE_HIGH is used analogously to WP line: in GPIO mode it is used only at probe time to switch polarity, for native mode it is left as is. Signed-off-by:

Use MMC_CAP2_RO_ACTIVE_HIGH flag as indicator if GPIO line is to be inverted compared to DT/platform-specified polarity. The flag is not used after init in GPIO mode anyway. No functional changes intended. Signed-off-by:

Add possibility to toggle active-low flag of a gpio descriptor. This is useful for compatibility code, where defaults are inverted vs DT gpio flags or the active-low flag is taken from elsewhere. Acked-by:
