mmc: sdhci: split up sdhci.h for sdhci-pltfm users
Some platforms based on sdhci-pltfm need to set their own quirks. Previously to this patch, the quirks were in drivers/mmc/host/sdhci.h. This patch splits drivers/mmc/host/sdhci.h into two parts: * drivers/mmc/host/sdhci.h includes the HC registers and I/O accessors. * include/linux/mmc/sdhci.h includes the sdhci structure and quirks. Instead of including drivers/mmc/host/sdhci.h, -pltfm drivers should now include include/linux/mmc/sdhci.h and include/linux/sdhci-pltfm.h. This patch avoids adding/changing the calls/flags in the sdhci_pltfm_data structure. It has been tested on STM platforms (e.g. STx7106, STx7108, STx5206) where the driver is configured and used as shown in the example below: [snip] static int mmc_pad_resources(struct sdhci_host *sdhci) { if (!devm_stm_pad_claim(sdhci->mmc->parent, &stx7108_mmc_pad_config, dev_name(sdhci->mmc->parent))) return -ENODEV; return 0; } static struct sdhci_pltfm_data stx7108_mmc_platform_data = { .init = mmc_pad_resources, .quirks = SDHCI_QUIRK_NO_ENDATTR_IN_NOPDESC, }; static struct platform_device stx7108_mmc_device = { .name = "sdhci", [snip] Note: drivers/mmc/host/sdhci.h now also includes linux/mmc/sdhci.h, and no modifications should be needed on other sdhci-<XXX> drivers.
