v2: - Grab dpio_lock mutex in vlv_enable_dsi_pll(). - Add and call vlv_disable_dsi_pll(). v3: Mostly based on Ville's review comments. - Only pipe A has DSI PLL lock bit. - Add more of CCK REG bit definitions for DSI PLL. - Make tables static. - Move clock gating out of the clock calculation functions. - DSI PLL LDO power gating. - Put alternative MNP from table calc behind #ifdef. v4: s/CKK/CLK/ in the CCK REG bit definitions (Ville).
