[PATCH v5 0/3] ASoC: rockchip: i2s: switch BCLK to GPIO

[Judy Hsiao]

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

Changes Since V5:
    -- Check i2s->pinctrl is valid before using pinctrl_lookup_state.
Changes Since V4:
    -- Fix indentation in the driver. (Align parameters with the parenthesis
       placement.)
    -- Fix incorrect return type of rockchip_snd_rxctrl.
Changes Since V3:
    -- Fix indentation in the documentation.
    -- Put pinctrl-1 right after pinctrl-0 in dtsi.
    -- Fix indentation in the driver.
    -- Remove unnecessary dev_dbg() in the driver.
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.
