One is the physical host(PH) that the same as conventaional UFSHCI, and the other is the virtual host(VH) that support data transfer function only. In this structure, the virtual host does not support UIC command. To support this, we add the quirk and return 0 when the UIC command send function is called. Cc: Alim Akhtar Cc: James E.J.

One is the physical host(PH) that the same as conventaional UFSHCI, and the other is the virtual host(VH) that support data transfer function only. In this structure, the virtual host does not support like device management. This patch skips the physical host interface configuration part that cannot be performed in the virtual host.

This requires control UFS IP sharability register via syscon and regmap. The offset of the register can be different according to the ufs instance and SoC specific offset value. So, we need to get the offset value from DT property. Unlike exynos7, it has different m-phy setting so it can be configured by exynosauto_ufs_pre_link.

In general, we're using para-virtualized driver to support a block device by several virtual machines. However, it should be relayed by backend driver. Multi-host functionality extends the host controller by providing register interfaces that can be used by each VM's ufs drivers respectively. By this, we can provide direct access to the UFS device for multiple VMs. It's similar with SR-IOV of PCIe. We divide this M-HCI as PH(Physical Host) and VHs(Virtual Host). The PH supports all UFSHCI functions(all SAPs) same as conventional UFSHCI but the VH only supports data transfer function. Thus, except UTP_CMD_SAP and UTP_TMPSAP, the PH should handle all the physical features. This patch provides an initial implementation of PH part. M-HCI can support up to four interfaces but this patch initially supports only 1 PH and 1 VH. For this, we uses TASK_TAG[7:5] field so TASK_TAG[4:0] for 32 doorbel will be supported. After the PH is initiated, this will send a ready message to VHs through a mailbox register. The message handler is not fully implemented yet such as supporting reset / abort cases.

VH(Virtual Host) only supports data transfer functions. So, most of physical features are broken. So, we need to set below quirks. - UFSHCD_QUIRK_BROKEN_UIC_CMD - UFSHCD_QUIRK_SKIP_PH_CONFIGURATION Before initialization, the VH is necessary to wait until PH is ready. It's implemented as polling at the moment.
