From: Faiz Abbas <faiz_ab...@ti.com> Add support for the controller present on the AM64x SoC.
There are two instances: sdhci0: 8bit bus width, max 400 MBps sdhci1: 4bit bus width, max 100 MBps Signed-off-by: Faiz Abbas <faiz_ab...@ti.com> Signed-off-by: Vignesh Raghavendra <vigne...@ti.com> Signed-off-by: Kishon Vijay Abraham I <kis...@ti.com> Signed-off-by: Aswath Govindraju <a-govindr...@ti.com> --- This patch is dependent on, https://lore.kernel.org/patchwork/patch/1361560/ drivers/mmc/host/sdhci_am654.c | 28 ++++++++++++++++++++++++++++ 1 file changed, 28 insertions(+) diff --git a/drivers/mmc/host/sdhci_am654.c b/drivers/mmc/host/sdhci_am654.c index a64ea143d185..7a34649b0754 100644 --- a/drivers/mmc/host/sdhci_am654.c +++ b/drivers/mmc/host/sdhci_am654.c @@ -514,6 +514,26 @@ static const struct sdhci_am654_driver_data sdhci_j721e_4bit_drvdata = { .flags = IOMUX_PRESENT, }; +static const struct sdhci_pltfm_data sdhci_am64_8bit_pdata = { + .ops = &sdhci_j721e_8bit_ops, + .quirks2 = SDHCI_QUIRK2_PRESET_VALUE_BROKEN, +}; + +static const struct sdhci_am654_driver_data sdhci_am64_8bit_drvdata = { + .pdata = &sdhci_am64_8bit_pdata, + .flags = DLL_PRESENT | DLL_CALIB, +}; + +static const struct sdhci_pltfm_data sdhci_am64_4bit_pdata = { + .ops = &sdhci_j721e_4bit_ops, + .quirks2 = SDHCI_QUIRK2_PRESET_VALUE_BROKEN, +}; + +static const struct sdhci_am654_driver_data sdhci_am64_4bit_drvdata = { + .pdata = &sdhci_am64_4bit_pdata, + .flags = IOMUX_PRESENT, +}; + static const struct soc_device_attribute sdhci_am654_devices[] = { { .family = "AM65X", .revision = "SR1.0", @@ -737,6 +757,14 @@ static const struct of_device_id sdhci_am654_of_match[] = { .compatible = "ti,j721e-sdhci-4bit", .data = &sdhci_j721e_4bit_drvdata, }, + { + .compatible = "ti,am64-sdhci-8bit", + .data = &sdhci_am64_8bit_drvdata, + }, + { + .compatible = "ti,am64-sdhci-4bit", + .data = &sdhci_am64_4bit_drvdata, + }, { /* sentinel */ } }; MODULE_DEVICE_TABLE(of, sdhci_am654_of_match); -- 2.17.1
