| * phy: qcom-ufs: Don't return error if fail to get optional resourceAxel Lin2015-04-031-20/+3
| | | | | | | | | | | | | | | | | | | | | | "dev_ref_clk_ctrl_mem" is optional resource, so don't return error if fail to get the resource. Since it's an optional resource, don't emit error if fail to get dev_ref_clk_ctrl_mem. Also remove redundant test for res, it's done by devm_ioremap_resource().

| | | | | | | | | | | | | | | | | | Current code does NULL test against return value of ufs_qcom_phy_generic_probe. However, in the case of devm_phy_create() failure, ufs_qcom_phy_generic_probe does not return NULL. Fix it.

* phy: qcom-ufs: add support for QUALCOMM Technologies UFS PHY driversYaniv Gardi2015-01-201-0/+745
This change adds a generic and common API support for ufs phy QUALCOMM Technologies. This support provides common code and also points to specific phy callbacks to differentiate between different behaviors of frequent use-cases (like power on, power off, phy calibration etc).
