2020-01-20mmc: sdhci-milbeaut: Remove redundant platform_get_irq error messageYueHaibing1-3/+1
platform_get_irq() will call dev_err() itself on failure, so there is no need for the driver to also do this. This is detected by coccinelle.

2020-01-20mmc: sdhci: fix minimum clock rate for v3 controllerMichał Mirosław1-4/+6
For SDHCIv3+ with programmable clock mode, minimal clock frequency is still base clock / max(divider). Minimal programmable clock frequency is always greater than minimal divided clock frequency. Without this patch, SDHCI uses out-of-spec initial frequency when multiplier is big enough: mmc1: mmc_rescan_try_freq: trying to init card at 468750 Hz [for 480 MHz source clock divided by 1024] The code in sdhci_calc_clk() already chooses a correct SDCLK clock mode.

2020-01-20mmc: sdhci: add support for using external DMA devicesChunyan Zhang3-2/+237
Some standard SD host controllers can support both external dma controllers as well as ADMA/SDMA in which the SD host controller acts as DMA master. TI's omap controller is the case as an example. Currently the generic SDHCI code supports ADMA/SDMA integrated in the host controller but does not have any support for external DMA controllers implemented using dmaengine, meaning that custom code is needed for any systems that use an external DMA controller with SDHCI. Fixes by Faiz Abbas <[email protected]>: 1. Map scatterlists before dmaengine_prep_slave_sg() 2. Use dma_async() functions inside of the send_command() path and call terminate_sync() in non-atomic context in case of an error.

2019-12-18mmc: mmci: Support any block sizes for ux500v2 and qcom variantLinus Walleij2-5/+37
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.
