[PATCH RESEND v7 0/2] Add SDHCI support for APM X-Gene SoC using ARASAN SDHCI controller.

This patch adds the SDHCI support for APM X-Gene SoC using ARASAN SDHCI controller. v1 change: * Use the CONFIG_ARM64_DMA_HAS_IOMMU for dma-mapping. v2 change: * Drop the IOMMU support and switching to PIO mode for arasan. controller integrated inside APM X-Gene SoC. v3 change: * Change t

[PATCH v3 1/2] mmc: sdhci: fix abort due to missing runtime PM

When using i.MX ESDHC driver, while entering suspend while the device is in runtime PM, the sdhci_(suspend|resume)_host function are called with disabled clocks. Since this functions access the SDHC host registers, this leads to an external abort on Vybrid SoC: [ 37.772967] Unhandled fault: impr
