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.
