Since commit 1599069a62c6 ("phy: core: Warn when phy_power_on is called before phy_init"), below warning has been reported. phy_power_on was called before phy_init To address this, we need to remove phy_power_on from exynos_ufs_phy_init. The first patch is for changing phy clocks manipulation from controlling each symbol/ref clocks to clk_bulk APIs. The second patch is for making power on/off sequences between pmu isolation and clk control. Finally, the third patch changes the phy on/off and init sequences from ufs-exynos host driver.
