The patches series is to fix the unexpected large
DC output voltage of Max98357a to burn the speakers 
on rockchip platform when BCLK and SD_MODE are ON but LRCLK is OFF.

Changes Since V2:
    -- Add documents of i2s pinctrl-names.
    -- Fix dtsi syntax error.
    -- Include the dtsi change and the driver change in the same series.
    -- Ensure that driver gets both bclk_on and bclk_off states before using them.
