Right now the qcom-ufs exports a bunch of APIs that are used by the host controller to initialize the phy. With this patch series, we populate the phy_init() which was a no-op earlier. The host controller then calls the phy_init() at the designated place rather than doing it invariably in ufs_hcd_init(). As part of this series, we introduce phy modes for ufs phy. The M-PHY has two data rates defined for each generations (Gears) - Rate A and Rate B. These can serve as the two modes of ufs HS phy. Host controller can direct the phy to set the respective configurations based on the phy modes. The patch-series has been tested with necessary dt patches on db820c.
